evt safety valve testing factory

The Electronic Valve Tester, (EVT), is a digital computerized, hydraulic assisted device, designed to test and set safety/relief valves while in service. The EVT is portable and can be used under normal operating conditions without over pressuring the system.

Our Factory and National Board certified technicians, provide total safety/relief valve evaluation utilizing EVT technologies... at your convenience. The Electronic Valve Tester has been approved by the ASME for set point evaluation and or adjustment.

EVT service eliminates the need to overpressure the system for testing. Under normal operating conditions, we save test medium and unnecessary stress on the overall system.

Control Valve Testing is the best way to make sure your current system is performing to an optimal standard. If you’re curious about where your valves are falling short or how you can improve their performance, Pioneer has the solution to get your safety relief valves where they need to be. At Pioneer, we provide specialized equipment to help your pressure relief valves adhere to required standards and certifications. The EVT-Pro from GE offers cutting-edge testing, diagnostics, and reporting for your valves for comprehensive evaluation. The EVT-Pro works for all brands of pressure relief valves.

ValvKeep® IIis a state-of-the-art, fully customizable valve management database system designed to assist our customers with the storage, management and maintenance of their safety, safety relief, control and block/line valve historical information. With a variety of reporting methods, this program can greatly assist our customers in maintaining their equipment with day-to-day and outage maintenance needs required to comply with OSHA regulations.

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.

vpl has put you on the right track. The Trevitest Device is one brand of Lift Assist Device (others include KISS, EVT, PVT AVK, Hydroset, SPIVOT). SOme are manufactured by Pressure Relief Valve Companies, others by Valve Repair Shops and some are third party vendors with PRV background. A Pressure Relief Valve typically uses a spring (Force S) to hold a movable sealing member (disc) closed on a fixed sealing member (nozzle) until the system pressure (Force P) overcomes the Spring and opens the PRV to relieve an overpressure situation. The PRV works on the simple principle that IF Force S > Force P THEN the PRV remains closed (Static Force Balance Principle). However, IF Force P > Force S THEN the PRV is Open.

The problem is that most Steam Power Generating Stations, whether Fossil or Nuclear, are such high pressure and under so much demand for electricity that they do want to take the time or liability to overpressure their boilers to test Safety Valve Set Pressure. Use of the Lift Assist Device is permitted by ASME Code (both Sec. I, Power Boilers, & Sec. VIII, Pressure Vessels) to determine the Set Pressure of a PRV (Safety, Safety-Relief or Relief Valve).

The Equipment Required is a Calibrated System Pressure Gauge, a Lift Assist Device with an adapter to connect to the PRV Stem, a Calibrated Load Cell to measure the Force Applied to the PRV Stem, a calculator or PC with a program to determine the Set Pressure from the input data and most importantly, a Valve Technician who knows PRV Terminology, and is familiar with the Test Equipment.

Dynamic Engineering Design prepared a maintenance schedule for over 200 relief valves in accordance with the National Board recommendations and based on the service conditions of each valve. Services included compressed air, water, oil, nitrogen, argon, carbon dioxide, and steam.

Dynamic Engineering Design coordinated required outages and scheduled the maintenance actions which include replacing valves, in service testing of valves (EVT – electronic valve testing), and on-site bench testing by a certified valve repair (VR) corporation.

6 consolidated Valves - EVT*-Pro Valve Testing Device | 54 | GE EnergyHow EVT-Pro WorksNormally, with the Pressure Relief valve online, the much stron-ger force of its spring -- F1 -- is all that is required to prevent system inlet Pressure -- F2 -- from forcing the valve open. However, should F2 increase beyond the operational limit of the system, the valve will first simmer and then prevent the valve from discharging during the EVT-Pro test, the GE-trained service technician introduces just enough pull on the spindle F3 -- to balance the force of the spring. This causes the disc to only crack open or this point the GTC Technician can read the set Pressure from the graphic display of the EVT-Pro and determine if it is set Balance Analysis: F3 + F2 = F1F3 = Artificial pull on the spindle supplied by the hydraulic pumpF1 = Spring force pressing down on the discF2 = Inlet Pressure pushing upward against the discExclusively Available Through Your Local GTC*GE s GTC Network Consists of More Than 80 Facilities Located in More Than 30 Countries WorldwideGreen Tag Center NetworkMore than 125 Years of ExpertiseConsolidated Pressure and safety Relief Valves from GE Oil & Gas have been available for more than 125 years.
