Selection Guidelines
When selecting a PSNO Valve, the following recommended flow ranges should be considered to ensure proper sizing and performance.
It is recommended not to oversize the PSNO Valve. In relation to the specfic flow (GPM), an oversized valve will require the diaphragm to be almost closed in the sustaining mode which can create high velocity, unstable regulation and potential cavitation.
Ordering Example
Pipeline: 6”
Required Flow Rate: 500 GPM
With a flow rate higher than 400 GPM, but lower than 600 GPM, a 4” valve is recommended. In this example, even though the pipeline is 6”, a 6” valve is not recommended.
