Chemical Injection Application
The valve is installed at the discharge-side injection point of a chemical metering system. Its one-way check mechanism helps resist process backflow while permitting metered chemical delivery into the process stream.
FPP Housing and Hypalon Seat
The FPP housing and CSPE/Hypalon seat identify the material configuration used in this valve. Verify the suitability of these materials for the actual chemical concentration and operating temperature.
PTFE Check Ball
J41773 uses a PTFE check ball rather than ceramic or stainless steel. The check-ball material should match the original pump specification to preserve the intended liquid-end configuration.
PHT3 Wet-End Compatibility
Distributor documentation lists J41773 for PHT3 wet ends with 1/2-inch OD tubing. The related J41772 assembly uses 3/8-inch OD tubing and is listed for PHT1 wet ends. Confirm the complete pump model before selecting a replacement.
Connection and Installation
Match the 1/2-inch OD discharge tubing and 1/2-inch male NPT injection fitting. Secure the tubing coupling according to the manufacturer instructions and avoid overtightening plastic components.
Maintenance and Inspection
Inspect the check valve for chemical buildup, leaks, damaged fittings and contamination. Isolate and depressurize the chemical feed system before removal or replacement.
