What is the maximum working pressure of the 17PCV check and 17PFV foot valves?
The PVC poppet type check valves (17PCV series) and PVC foot valves (17PFV series) are rated at a maximum working pressure of 150 PSI at 73 °F (1034 kPa at 22 °C). They are designed for cold water applications. For hot water applications, special high temperature valves must be used, and the manufacturing factory should be contacted.
PVC pressure ratings must be reduced as operating temperatures increase. For pressure derating factors see the article at the link below.
