Spring-and-Poppet Check Valves—C, CA, CH, CP, and CPA Series
 
Swagelok® spring-and-poppet check valves are available with nominal cracking pressures ranging from 1/3 to 600 psi (0.03 to 41.4 bar) in 316 stainless steel and brass and with end connections 1/8 to 1 in. and 6 to 25 mm in size.

Lift Check Valves—50 Series

Swagelok® lift check valves limit reverse flow under pressures up to 6000 psig (413 bar) and temperatures up to 900°F (482°C). Forward flow lifts the poppet, opening the valve. Reverse flow seats the poppet against the orifice, closing the valve. The Swagelok lift check valve is gravity assisted and must be mounted horizontally, with bonnet nut on top.
 
All-Welded, High-Purity Check Valves—CW Series
 
With all-welded 316L stainless steel body and springless design, the Swagelok® CW series high-purity check valve is designed for clean operation and reliable fluid containment.
 
Swagelok® UHP Check Valves, O-Ring–Free Fluoropolymer—CHP Series
 
CHP series UHP fluoropolymer check valves provide low cracking and reseal pressure and contain wetted components that meet SEMI Standard F57-0301 for ultrahigh-purity system components.
