Chemical Injection Back-Pressure Function

The injection valve is designed for the discharge-side chemical injection arrangement. It helps provide the intended back-pressure condition while resisting reverse flow from the process system into the chemical feed line.

10 PSI Configuration

The part number suffix identifies a 10 PSI valve configuration. This designation should not be interpreted as the maximum allowable operating pressure of the complete chemical metering system. Verify all system pressure limits separately.

PVC and PTFE Construction

The PVC body and PTFE seat distinguish this valve from FPP-bodied or elastomer-seated injection assemblies. Material compatibility must be checked against the chemical concentration, operating temperature and service conditions.

Stainless Steel Check Component

The manufacturer parts listing uses the material designation PVC/TFE/S. It confirms a stainless steel check component but does not specify the steel grade. Confirm the exact material before use with chemicals that may attack stainless steel.

Connection and Replacement Selection

The published connection designation is 1/2-inch NPT. Confirm the original mating fitting, complete pump configuration and required pressure designation before ordering.

Installation and Maintenance

Inspect the valve for deposits, leakage and damaged threads. Follow the manufacturer installation procedure and relieve system pressure before servicing the injection assembly.
