Check Valves – Technical Datat

(Pipe) O-ring Check Valves
• Provide unidirectional flow and tight shut-off for liquids and gases with high reliability (Not for use as relief valve)
• Resilient O-ring seat design for noise-free closing and zero leakage
• Cracking pressure: 14 psig~26 psig (0.966 bar~1.794 bar)

(Pipe) Ball Check Valves
• Prevent reverse flow where leak-tight shut-off is not mandatory (Not for use as relief valve)
• An integral design of the ball and poppet to assure positive, in-line seating without “chatter”. Poppet designed essentially for axial flow with minimum pressure drop
