Series CSCheck ValvesManatrol Series CS Check Valves permit free flowin one direction, and total shutoff automatically inthe reverse direction.
Stainless steel poppets, not balls, are standard onall Series CS Check Valves. Poppets eliminatechatter and, minimize wear.
Operating pressures: 3000 PSI (210 Bar) max.
Cracking Pressures, nominal: 5 PSI (0.3 Bar)
Standard Options: 20 PSI (1.3 Bar)65 PSI (4.5 Bar)
(Other cracking pressures may be available onrequest)
Poppet Style: Solid metal poppet
