All-Stainless Steel Union Bonnet Check Valves
CL Series 
CL Series Metal-Seated Lift Check Valves feature a rugged, all-stainless steel construction with a metal-to-metal seal. These valves are free of spring or elastomers, and their union bonnet design adds safety. The lift poppet is gravity-dependent, with a reverse flow coefficient of less than 0.1% of the forward flow coefficient. These valves prevent reverse flow up to 6000 psig (413 bar) and 900°F (482°C).
Features
- Working pressure up to: 6000 psig (414 bar)
- Working temperature: -65°F to 900°F (-53°C to 482°C)
- Rugged, all-stainless steel construction
- Union bonnet design, horizontal installation with bonnet nut on top
- Reverse flow coefficient less than 0.1% of forward flow coefficient
Cleaning and Packaging:
FC-01: Standard cleaning and packaging for general industrial procedures.
FC-02: Special cleaning and packaging for wetted system components to ensure compliance with product cleanliness requirement of ASTM G93 Level C
Cracking Pressure and Resealing Pressure
Cracking pressure – the upstream pressure at which the first indication of flow occurs.
Reseal pressure – the pressure at which there is no indication of flow.
