NWS Technologies contaminated steam test stands have the capability to test pressure relief valves up to 2800 psig at saturated temperature. Our boiler provides steam rated at greater than 98% steam quality. The two test stands have equivalent capabilities for all size valves up to 20” inlet and 24” exhaust. We have developed a proprietary test software for recording valve lift parameters on the steam test stand. This data includes valve set-pressure, lift profile, temperature profile, and other valve-specific data, as necessary.
NWS Technologies has the capability to test liquid, oil, air, gas, and nitrogen pressure relief valves. We have multiple test stands for a wide range of pressures and valve sizes.
Our test program is designed in accordance with ASME Operation and Maintenance of Nuclear Power Plants, Mandatory Appendix I (OM-I), and ASME Performance Test Code PTC 25, Pressure Relief Devices.
