❉maximum working pressure up to 20000psig(1379 bar)
❉working temperature from -110℉ to 1200℉(-79 ℃to 649℃)
❉tubing sizes available from 1/4" to 1 " in
❉o-ring check valves cracking pressure from 14 to 26 psig (0.966 bar to 1.794 bar)
❉o-ring check valves provide unindirectional flow and tight shut-off for liquids and gases with high reliability
When differential drops below cracking pressure ,valve shuts off(not for use as relief valve)
❉o-ring check valves provide resilient o-ring seat design for noise-free closing and zero leakage
❉ball check valves prevent reverse flow where leak-tight shut-off is not mandatory (not for use as relief valve)
❉ball check valve is an integral design of ball and poppet to assure positive ,in-line seating without “chatter"
poppet is designed essentially for axial flow with minimum pressure drop
❉ ball check valve has optional wetted materials of cover gland and ball poppet for longer life.
