Safety Relief Valve Tester & Testing System, Relief Valve Test Bench, Safety Valve Testing Machine
Safety Valve Test Machine, Pressure Relief Valve Test Bench, Valve Test Bench, Pressure Test Machine for Safety Valve, Pressure Relief Valve Test Machine, Computer Control Safety Valve Test Machine, Automatic Control Safety Valve Test Bench
Safety Valve Test Machine, Pressure Relief Valve Test Bench Equipment is used for comprehensive performance testing of safety valves, including design performance tests of gas safety valve flow rate, cracking pressure, cracking pressure difference, and cracking height. The equipment has advanced design principles, and adopts the Simint data acquisition system, which can store and retain the safety valve measurement data for a long time, query and generate hard copies and archives, and can directly generate verification reports with computer database storage.
Safety valve test bench uses high-pressure air as the medium to do testing for the sealing performance, and uses Shineeast high pressure pump as the power source to realize activated pressure testing and reseating pressure testing of the safety valve.
Features of Safety Valve Test Bench
Spring safety valves, pressure relief valves, and spring stem exposed threads are widely used.
The instrument has a USB interface that can transmit the measurement data to the microcomputer to realize the scientific system management of data storage, query and display safety valve.
Equipped with an independent low pressure detection system, which can be adjusted steplessly according to the low pressure, it is more convenient to detect the low pressure safety valve and protect the precision pressure gauge from damage.

What’s Pressure Safety Valve (PSV)
Pressure Safety Valve (PSV) is a type of Pressure Relieving Device (PRD) also is a failsafe used to protect people, that is used to release gases or liquids, and thus relieve pressure, in the case that the pressure in a vessel reaches a pre-determined setpoint. Pressure safety valve are essential to the protection of lives and equipment, The purpose of a safety valve is to be the last line of defense in protecting equipment, the environment, and most importantly personnel. particularly in the oil & gas, power generation, water/wastewater, aerospace/aviation, steel manufacturing, and chemical/plastics industries.
Because of the importance of a PSV, the valve must be able to operate at any time in any condition. They are purely mechanical so they’re capable of operating at all times and are considered the last resort in preventing catastrophic failure in systems under over pressure conditions. Pressure safety valve should be used as a final measure to prevent accidents, rather than consistently maintaining pressure. Because of this, pressure safety valves are heavily regulated and must meet ASME Code requirements.
The Importance of PSV Testing
A Pressure Safety Valve (PSV) is a final link in the safety chain and these must work properly to safeguard the system. To ensure that the PSV will work smoothly and open when the need arises, safety valves need frequent testing to ensure they’re in good operating condition and functioning properly. The mechanical parts can stick closed, wear over time and exposure to contaminants and corrosion can affect the resealing or closing of the valve seat after release that could result in a leak. Depending on the industry in which they’re being used, it’s recommended that they’re tested at least every 1-3 years, or more frequently depending on previous inspection history.
