Check-Valve Function
The valve provides a one-way flow path at the chemical injection connection. Its check mechanism helps resist reverse flow of process liquid toward the pump discharge tubing.
FPP and Viton Construction
The FPP housing and Viton seat distinguish this valve from PVC-bodied or PTFE-sealed alternatives. The ceramic ball forms part of the internal check mechanism. Verify all wetted materials against the chemical service conditions.
Importance of Tubing Dimensions
The manufacturer parts table identifies both tubing inside and outside diameters. The 1/2-inch OD dimension is important for connection selection; verify the existing tubing before ordering a replacement.
Installation and Maintenance
Inspect the injection connection for leaks, deposits and damaged fittings. Isolate the chemical system and relieve pressure before servicing the valve. Follow the original pump installation instructions.
