How to check the fit
Match all wetted materials
Check the fluid, concentration, temperature and solids against the fluid section, diaphragm and ball/check-valve materials. Matching port size alone does not establish chemical compatibility.
Match connections and operating duty
Confirm the thread or flange standard, required flow at discharge pressure, air supply and suction conditions. Maximum catalog flow is not the delivered flow at every operating point.
