Chemical Injection and Back-Pressure Function
Injection back-pressure valves are installed at chemical feed connections to support the intended discharge conditions of a metering pump. The internal check mechanism helps resist reverse flow from the process line toward the chemical feed system.
10 PSI Valve Designation
The part number suffix and distributor listings identify this assembly as a 10 PSI configuration. This designation should not be interpreted as the maximum allowable pressure of the complete chemical feed installation. Confirm the applicable pressure and installation requirements from the manufacturer.
PVC, PTFE and Ceramic Construction
The PVC housing, PTFE seat and ceramic ball distinguish this assembly from valves using Viton, Hypalon or stainless steel check components. All wetted materials must be compatible with the actual process chemical.
Connection and Compatibility
Verify the original 1/2-inch NPT fitting and complete pump configuration. Similar injection valves can have different pressure designations, connection types or internal materials.
Maintenance and Inspection
Inspect the valve for chemical deposits, leakage, damaged threads and contamination of the check ball and seat. Isolate and depressurize the chemical feed system before servicing.
