Injection Point Check-Valve Function
The valve connects the chemical discharge line to the process system. It provides a one-way check function that helps resist backflow into the metering pump tubing.
PTFE Ball and Hypalon Seat
The PTFE check ball and CSPE seat are defining characteristics of J41758. They distinguish it from Viton-sealed or ceramic-ball alternatives and should be matched to the original wet-end configuration.
Correct Tubing and Thread Selection
The valve uses 3/8-inch OD discharge tubing and a 1/2-inch male NPT injection connection. Confirm the tubing, coupling nut and process fitting before installation.
Installation and Maintenance
Follow the manufacturer instructions for attaching the tubing and securing the connection. Inspect the valve for deposits, damaged fittings and leakage, and depressurize the system before service.
