Model C220A Cartridge Check Valve

Description

Circle Seal Controls Model C220A Cartridge Check Valve

Catalog literature: Check Valves Catalog.pdf

The Circle Seal Controls model C220A Cartridge Check Valve is constructed in Aluminum with a Teflon seal and is available for installation in bore diameters ranging from 3/4″ to 1-5/8″.

Features and benefits:

• Positive sealing at any differential pressure: absolute bubble-tight in leakage tests
• Quick opening / positive closing: even at extremely low pressure differential; opening pressures can be supplied as low as a few inches of water; the poppet closes at zero flow before the return flow starts
• Maintenance-free dependability: the streamlined poppet and full ports offer minimum restriction to flow; the spring retainer has ample ports to allow full flow even where surge pressure forces the poppet against the stop
• No “chatter” or “hammer”: the pulsating action of shock waves and hammer is absorbed by minor expansion and contraction of the o-ring; the use of the resilient o-ring seal, together with the careful poppet design, insures cushioned, quiet closing
• Satisfactory performance under adverse conditions: foreign particles in the fluid stream do not prevent proper sealing; temperature variations do not affect proper functioning of the valves; can be supplied to withstand temperatures from -100 to +400F
• Adaptable to most fluids: metallic and non-metallic parts can be supplied to withstand the action of most commonly used industrial fluids; no special wear resisting materials are required, eliminating the problems of differential expansion and electrolytic action from dissimilar metals
• Compact, easily installed: efficient, straight-line design reduces weight and size; designed to be installed in cavities machines into the manifold or cylinder, eliminating bulky, complicated mazes of conventional valves and piping
• Simplifies, streamlines product design: permits complete sequences of automatic operations in a small space; cuts material and component costs; reduces assembly work and speeds up production

Technical Data:

• Operating pressure: 0 to 5,000 psig
• Body material: Aluminum
• Seal material: Teflon
• Temp range: -100 to +400F
• Durometer: N/A
• Cracking pressure: 8 PSIG max.

Notes:

• Cracking pressure is defined at which flow is 5 cc/min except for C220 series valves (with PTFE seal) for which flow is approximately 0.02 cfm.
• Standard cracking pressure is noted above. Special cracking pressures may be available upon special request, contact Sales for assistance (min cracking pressure available = 0.1 psi; max cracking pressure available = 25 psi).
• Proper filtration is recommended to prevent damage to sealing surfaces.
• Valves are furnished complete with o-ring and backup ring.
