avk safety valve testing brands
relief valve industry. This vast knowledge, coupled with continuous customer input, allows AVK to provide the first in-line pressure relief valve testing devices designed specifically with you in
with your specific application, and make the testing of pressure relief valves a cost effective way of ensuring plant safety with the utmost in flexibility.
A very critical aspect of inline testing is the accuracy of effective seat areas that are used in calculating set point, our products have been proven by comparative live testing and empirical
analysis through many years. Our Nuclear software has passed V & V certification. Our products have been independently verified for accuracy by major valve manufacturers and
operator hears the valve open he releases the hydraulic line pressure and the computer records all data and calculates set pressure. Unit includes computer, 2 batteries, power supply/charger,
Safety valves are used in a variety of industrial applications to include air/gas, vapor, steam, and liquid service, among many more. These pressure relief valves are critical to the safe operation of our customer’s equipment and provide—as their name implies—a safety measure that can reduce the number of risks that can threaten both your personnel and facilities.
Millennium Power Services’ safety valve technicians will get your valves tested, repaired, and quickly set to the exact specifications. We serve as your knowledge partner and will also evaluate the repair condition of every valve and make recommendations as needed to help you make the best decisions.
Using the data acquired through system transducers, the AVK consistently and accurately verifies valve set pressure. The portable device includes a small actuator assembly that is mounted to the valve. A custom-designed adapter with sensor applies force to the valve spindle to determine set pressure. The test results can then be printed or downloaded to other applications.

Valsource provides 24/7 repair and testing services in our shop or in the field. Our valve program allows our technicians to repair, remove, install and test your pressure relief and safety relief valves on-site. Using our AVK Electronic Test Vessel Package, our technicians are able to accurately test safety relief valves on-site without removing them from line. The primary function is to verify the set pressure in-line without having to shut down a system or unit. This service is a sure way to guarantee minimal downtime and peak valve performance. If you are preparing to service your boiler, Valsource technicians will come to your site and test each main steam safety valve to determine which valves require service. We will perform the repairs in-house or on-site using our 53’ field machining trailer, install and re-test back to calibrated set points.
If you need the best in valve repair and remanufacturing, Valsource can deliver the right options for your company. We offer rapid response times and emergency repair services available to resolve unplanned outages quickly. Our experienced technicians look forward to working with you to determine the most effective solutions for your valve repair needs.
ABBEY ROGERS offers a lift assist device that allows for the testing of safety relief valves while still in line, and operational. The AVK is an electro-hydraulic computerized testing unit that when connected to the valve records the pressure at which the valve lifts. The AVK connects to the stem of the safety valve and measures the vertical forces exerted by the spring and load train of the valve. These tests are preformed while your system is under pressure, therefore no loss of production due to removing safety relief valves. The documentation provided will satisfy ASME & Insurance inspectors.
Valve requirements for the AVK are the following: pressure under the valve, must be flanged, must be at least a 21" clearance above the valve, service must be non-liquid, and non-hazardous vapors. The AVK is ideal for testing valves in place which will determine which valves need to be pulled out of service for repair, and which can remain inline through another cycle. The AVK will reduce manpower and downtime expenses.
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.

AVK International A/S, a family-owned group of companies based near Aarhus, has been producing natural gas network valves for many years. As the transition to green energy becomes increasingly more important in supplying energy for the future, AVK is highly conscious of the significance of Power-to-X and green energy sources for its future portfolio of products.
"We want to be at the forefront of developments in transporting hydrogen through the natural gas network," explains Simon Slumstrup, a product manager at AVK International A/S. "That"s why we want to know if our valves can withstand long-term exposure to hydrogen."
One of the challenges with hydrogen is that it can diffuse into metals over time, such as the metal components of a valve. If this happens, it can cause the metal to become brittle and prone to developing cracks. Leaks and hydrogen-tightness are also focal points, given the small size of hydrogen molecules. In the worst-case scenario, an explosion could occur within a gas pipeline or in a Power-to-X system.
"We needed to have a test developed in order to determine whether our valves could withstand long-term exposure to hydrogen. We can"t conduct these kinds of tests ourselves because they require extensive safety measures. Hydrogen is extremely flammable, and our valves have to be tested under pressure," says Slumstrup.
AVK and FORCE Technology collaborated to develop specialised, comprehensive tests based on FORCE Technology"s knowledge of the field. These specialised tests fulfilled AVK"s needs for a way to test the long-term impact of hydrogen on its valves under simulated operating conditions.
Two tests were developed: a functional test, which simulates a valve"s entire lifetime; and a burst test, which exposes a valve to increasingly high (and eventually unrealistic) pressures until it fails. A tested valve can then be compared to a control valve that underwent a lifetime test in an inert gas to determine whether the hydrogen damaged the tested valve.
