Ozone Compatible Check Valves

CVLP - Low Pressure Check Valve CVHP - High Pressure Check Valve CVSS - Stainless Steel Check Valve
Low pressure check valve for low pressure (less than 25 PSI) High pressure check valve for high pressures (up to 200 PSI) High pressure check valve for high pressures (up to 200 PSI)
Free floating diaphragm will seal with very small pressure differentials Stainless steel spring and ball provide positive, tight seal Stainless steel spring and ball provide positive, tight seal
Very low crack pressure < 0.25 PSI Crack pressure of ~2 PSI - (crack pressure may vary between valves) Standard valve uses 0.5 PSI crack pressure, other crack pressures are available upon request
Free floating diaphragm will not provide a positive seal every time, expect some water leakage through seal Crack pressure of ~2 PSI - (crack pressure may vary between valves) Open design offers very high flow, and very little flow restriction
Barbed fittings make this an easy check valve to install Male NPT connections require threaded connections to this valve Female NPT connections require threaded connections to this valve
Kynar construction and Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal Kynar construction and Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal Viton, or PTFE seal designs are available on stainless steel valves
    PTFE seal will be most ozone resistant and longest lasting seal available.
    Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal.
    Viton is very pliable and will offer the most reliable seal.
    PTFE is very rigid, small particulates will keep this material from offering a positive seal.
