online safety valve testing in stock

Different to a safety valve test bench test an online safety valve test (or ISVT – In Situ Valve Test) is carried out on site with the safety valve remaining in its operational position and the plant remaining in operation. Whenever a safety valve “only” requires testing and no further maintenance or overhaul, a TESON online safety valve test is the most economic approach. Those who are new to the subject kindly refer to our Online Safety valve testing white paper.

Safety valves are used in a variety of applications, including air/gas, vapor, steam and liquid service.  Flotech has been approved by the National Board of Boiler and Pressure Vessel Inspectors to perform safety and relief valve testing, repair and certification.

Our valve experts will focus on getting your valves tested, repaired and quickly set to the exact specifications.  We evaluate the repair condition of every valve and will recommend the right solution to manage your maintenance program.

The old way of pressure relief valve testing could be summarized in one word: downtime. First, the plant went down, then valves were disassembled, and finally, the valves were transported offsite for testing. Time-consuming. Costly. High risk. But using the AccuTEST System, pressure relief valve testing comes to you, right where the valves actually operate. Time saver. Cheaper. Lower risk.

The AccuTEST System is a recognized leader in the valve service and repair industry. Why? Think fully automated one-touch testing for ease of use and repeatable results. It’s compact and portable to reduce the load of pressure relief valve technicians. Ongoing product enhancement based on technicians’ input. And we offer responsive technical support, anytime, directly from our engineers – not from a third-party representative.

Our repair service center is designed to keep your customer’s safety and relief valves at peak operating efficiency. And put extra profits in your pocket.

North American’s Service Center is equipped to handle any safety valve repair. NASVI has the specifications for nearly every safety valve ever made—allowing technicians to make repairs to exact specifications. The center has six lathes on site, so technicians can restore tolerances on existing parts in quick order. If a part cannot be restored, it can generally be replaced from our extensive parts inventory.

Once repairs are complete, valves are tested and then set at one of six, fully equipped test stations. The boiler is on every day for testing steam valves. It’s always ready, allowing us to set and ship your valves fast.

Over the years, our Service Center has proven popular with maintenance managers. It allows the plant to have their valves repaired, serviced and set quickly, which minimizes downtime. They also like the service because it saves them money.

Our repair service also includes updating the valve to the latest design standard when necessary. All valves serviced in our repair facility carry a one-year standard warranty. North American holds ASME’s V and UV stamps and National Board’s NB and VR stamps. The next time your customer has questions about repairing or upgrading their safety or relief valves, give one of our application engineers a call.

You don’t have to be an expert in the field of safety and relief valves to sell them. We are here to help. Our goal is to make it easy for you to profit from the sales of safety and relief valves. Our expertise comes from taking care of our customers for over 42 years. And our large inventory allows us to offer same day shipment from stock on every valve Kunkle makes.

The sole responsibility of our dedicated applications engineers is to take care of your requirements. We will help you with sales planning, product selection and after sale service when needed. We will even provide you with catalogs that have no reference to NASVI. Our valuable advice is free and as close as your phone. So the next time your customer calls and needs a safety or relief valve, call a NASVI Applications Engineer.

They’ll have a quick answer on price, availability and shipment. When it comes to selling safety valves, you don’t have to stock anything. Simply call 1-800-800-8882 or visit us on the web at www.nasvi.com. We’ll make it easy for you!

Our two-truck unit responds to customer requests anywhere, offering on-site repair and resetting of safety valves during scheduled maintenance shutdowns.

Step into the mobile repair unit and you’ll find all the equipment necessary to perform highest-caliber repairs: sand blaster, compressor, lathe, mill/drill press, lapping machine–-it’s all inside. There’s also a Consolidated® seat-resurfacing machine with all adapters for every orifice in the Maxi-Flow® boiler line. Completed valve work will carry the VR stamp.

The Field Service Unit also includes a state of-the-art computerized lift-assist testing unit that allows for testing set pressures and resetting high-pressure safety valves in the field. The testing unit makes testing valves that are welded in-line or stationary possible without removing the valves. Your customers won’t be required to pressure down or increase pressure to test for set pressure. The lift assist testing unit also allows for resetting valves after repairs have been made while the valves are on-line.

If you have prospects or customers that bought their replacement valves elsewhere because you haven’t been able to provide on-site service, you will want to get back with them and talk about this service. If you have questions about pricing and scheduling of our Field Service Unit, give us a call at (800) 800-8882.

Pressure safety valves are designed to protect process piping and equipment in case of an overpressure event. TEAM Valve Solutions inspects, tests, repairs and re-certifies safety valves at 17 service centers across three continents, and in our fleet of mobile facilities, all of which are audited under the jurisdiction of relevant governing bodies.

Our solutions cover all major safety valve brands and support our customers through an inventory of spare parts and loose-assembled valves. In addition, our facilities are audited and governed by the National Board of Boiler and Pressure Vessel Inspectors. Testing, repair, and assembly are performed under license and guidelines of NBIC, and ASME Section I and VIII.

To ensure accurate in-line setpoint verification, TEAM Valve Solutions utilizes Trevitest, the pioneering system for validating safety valve performance in Conventional and Nuclear Power plants, as well as in other industrial process facilities.

Dismounting safety valves from their operational location can be time-consuming and expensive. The Seetru Tru-test® provides the capability to test safety and relief valves in-situ, eliminating the need to remove the valve from the system or shut the system down. In-situ testing of this form is part of a carefully planned and monitored test and maintenance regime, which also includes periodic strip down, inspection & overhaul, and a highly cost effective means of managing safety valve and relief valve inventories.

The Seetru Tru-test® system offers the capacity to test in real operating conditions. This provides added con dence in the protection afforded by the safety valve. It also supports the optimisation/ minimisation of maintenance downtime through Seetru operated condition monitoring of safety valves in service.

Tests can be “hot”, i.e. in-situ with medium pressure acting on the safety valve, or “cold”, i.e. on or off site and in-situ with no medium pressure acting on the safety valve.

Pre-programmed safety limits are sensed and managed automatically during the test cycle in order to prevent damage and to provide fail-safe operation.

Lift limitation is pre-established and provided to minimise the risk of valve damage or a full lift safety valve popping open during test. The computer controlled pre-programmed test eliminates the chance that the inherent vagaries of a human operator manually controlling the lift might result in the safety valve lifting.

The Seetru safety valve test method using the Tru-Test® system is widely approved, for instance, by Lloyds Register of Shipping and the Insurance Industry.

With an ever-increasing focus on reducing maintenance expenditure, there is a need for safety critical equipment to function reliably. With preventative maintenance on pressure safety valves (PSVs) being one of the more significant integrity costs, increasing efficiencies in this area is important, with potential for time savings and performance improvement.

The Pressure Safety Valve Manager digital tool is client-accessible and contains all the information used in the RBI, including the (pre-pop) results. Detailed tabs contain the PSV performance history for the asset(s). The tool may also communicate with the operator’s computerized maintenance management system (CMMS) to accurately relay, not only the performance history of each PSV, but also information useful for maintenance planning, such as shutdown requirements, online testing capabilities etc.

The EVT-Pro device simultaneously examines two critical variables of the relief device — the upward force applied to the spindle and the actual system pressure. Using sophisticated sensors, including an acoustic device, EVT-Pro testing accurately determines the pressure relief valve’s set pressure. It can also immediately sense and automatically close a relief device should it remain open during a test – a unique safety feature built into the software and hardware.

Testing the safety relief valve is extremely important to the overall safety of your boiler system. In this post, we’ll be talking about what goes into testing a steam relief valve, but safety valve repairs should only be performed by a company holding a current Certificate of Authorization (VR) from the National Board of Pressure Vessel Inspectors.

Using certified and calibrated gauges is essential to accurate testing. WARE’s own Rick Walker recommends using two gauges, for maximum accuracy and in case one isn’t properly functioning.

Relief valves need to open and close at very specific pressures, and also need to open smoothly. A smooth opening contains a clean “pop” sound, and not a simmering or chattering sound. Responding to the appropriate pressures and opening and closing cleanly are both important signs a professional maintenance provider will look for in a safety valve.

Safety valves contain a compression screw, which puts pressure on a spring and causes the valve to function. The compression screw is where a maintenance provider will try to dial in your valve’s functionality and make set-pressure adjustments. It’s important to note if a valve is cold it might test higher, but as the valve gets hotter its metal will expand and its innerspring will slightly decompress.

Once the valve is warm and has stabilized, it’s best to give it more than one test (Rick does three) to make sure the valve is consistent and within ASME code.

ASME defines a safety valve as properly functioning at 150 psi if it tests within 3% of the set pressure. If your valve tests within 3% of the set pressure three times in a row on properly calibrated gauges, you’re likely good to go.

Because of their importance, checking or calibrating valves is critical, but creating a consistent test result is difficult, as two technicians may interpret the analog test gauge differently.

Companies use pressure relief or safety valves to protect equipment from pressure spikes. Because of their importance, checking or calibrating these valves is critical, but creating a consistent test result is difficult, as two technicians may interpret the analog test gauge differently.

Crystal has a solution with its XP2i Digital Pressure Gauge. The XP2i features a special PSV mode designed to test pressure safety and relief valves. Once the valve opens, the XP2i detects the pressure drop and displays the maximum pressure that the gauge ever reached before the drop. This value remains on the display until the technician clears it. Rather than two technicians possibly reporting different values when the analog gauge spikes, with the XP2i both technicians would write the same value, even to a thousandth of a psi.

The XP2i Digital Pressure Gauge features three accuracy levels to choose from, 0.1% of reading, 0.05% of full scale, or 0.02% of full scale. They are available in ranges from vacuum to 15,000 psi and are fully temperature compensated from –10 to 50 C. All versions are ATEX, IECEx, and CSA intrinsically safe, making them ideal for the oil & gas industry and others requiring intrinsic safety. An optional datalogging upgrade allows the XP2i to collect and store up to 32,000 data points and easily download the results to a spreadsheet or protected pdf file.
