SV 20/200 PA
SV 20/200 PA (Pop Action)
The SV 20/200 PA from the METRUS SV series is a safety valve test bench designed for safety valves up to DN 200 (8”) and has been specifically developed for dynamic testing and pop action simulations. It is suitable for pressure setting, seat leakage testing, and functional verification after repair.
Realistic simulation of safety valve opening behaviour requires controlled flow conditions and sufficient gas volume. The PA system is equipped with a 20-liter gas reservoir and a 2” flow line to the test specimen, enabling realistic pressure relief conditions and high flow energy.
When the set pressure is reached, the valve opens abruptly (“pop effect”) and releases pressure at high speed. The system ensures controlled pressure decay, allowing the valve disc to reseat smoothly on a gas cushion while reducing mechanical stress during closing.
Testing can be performed with compressed air or nitrogen up to 300 bar. Pressure regulation is controlled via METRUS precision needle valves, ensuring stable and repeatable testing conditions.
As part of the METRUS safety valve test bench series, this system is designed for demanding dynamic testing and realistic functional analysis applications.
For larger safety valves up to DN 400, the SV 20/400 PA is also available within the same platform.
