SV 20/400 PA
Some safety valves are designed in such a way that a high discharge capacity is achieved when the set pressure is reached. This is achieved by the space above the valve seat having a much larger volume than the inlet area. When the set pressure is reached in the valve inlet, the seat opens abruptly with maximum stroke and relieves the pressure in the valve inlet at high speed. This response is often accompanied by a strong pop noise, which is why this is also referred to as a popping test.
To simulate such a situation on a valve test bench, a corresponding gas volume and a sufficiently high flow velocity are required.
For this purpose, METRUS offers a Pop Action (PA) safety valve test stand series. A gas reservoir with a volume of 20 litres and a pipe cross-section of 2” to the test specimen provide sufficient flow energy to achieve exactly this effect during a test. For gas pressure tests up to 300 bar, the large storage volume ensures that the valve seat closes gently again on a gas cushion when the pressure drops and is not damaged by hard mechanical contact.
This test stand model is available in two versions: The SVM 20/200 PA has a working range up to DN 200 / 8”, and the SV 20/400 PA can even test valves up to DN 400 / 16”.
