Parker CV-1-2266 Inline Check Valve 3/8 Inch Ptfe

Product Description

The PARKER CV-1-2266 is a 3/8 inch inline check valve constructed with a polytetrafluoroethylene (PTFE) body and PTFE spring. It is rated for 120 WOG (Water, Oil, Gas) service and allows flow in one direction only, preventing backflow in fluid and gas lines. The valve connects via PARGRIP fittings on both ends, making installation straightforward in systems where push-to-connect style connections are used. With a crack pressure range of 0.25 to 0.75 psi and a Cv rating of 0.980, this valve is suited for low-pressure applications where minimal resistance and reliable backflow prevention are required. Licensed plumbers, HVAC technicians, and industrial piping installers are the typical trades working with this component.

This valve is designed for inline installation in fluid handling, pneumatic, and light gas distribution systems. The PTFE construction makes it chemically resistant and appropriate for use in systems carrying corrosive media, deionized water, or other fluids incompatible with metal-bodied valves. It operates across a temperature range of -32 degrees F to 130 degrees F, covering most residential and light commercial mechanical system environments. The 3/8 inch pipe size and PARGRIP x PARGRIP end connections position it for use in tubing runs where secure push-to-connect fittings are already part of the system design.

Key Features

• PTFE body and spring for excellent chemical resistance in corrosive or high-purity fluid applications
• Crack pressure of 0.25 to 0.75 psi enables reliable one-way flow with minimal upstream pressure required
• Cv rating of 0.980 supports low-restriction flow through the valve body
• PARGRIP x PARGRIP end connections for push-to-connect installation without additional fittings
• 120 WOG pressure rating suitable for water, oil, and gas service
• Operating temperature range of -32 degrees F to 130 degrees F covers most mechanical system conditions

Compatibility

Designed as an OEM-style inline check valve for 3/8 inch pipe systems using PARGRIP push-to-connect fittings in fluid, pneumatic, or light gas service applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician familiar with the system media and applicable codes. Shut off and depressurize the line completely before removing any existing fittings or inserting this valve. Verify the flow direction arrow on the valve body is oriented correctly with system flow before seating the PARGRIP connections. PTFE components should not be exposed to temperatures, pressures, or chemical media outside the rated limits.
