Injection-Point Backflow Protection
The valve provides a one-way chemical injection path at the receiving process line. Its check mechanism helps resist reverse flow toward the metering pump discharge tubing.
Viton Seat and Stainless Steel Ball
The Viton seat and 316 stainless steel ball are distinguishing specifications. They should match the original liquid-end materials and be suitable for the process chemical.
3/8-Inch OD Tubing
The tubing connection is designed for 3/8-inch outside-diameter tubing. Confirm the matching coupling and 1/2-inch male NPT process connection before ordering.
Material Compatibility
Neither FPP nor Viton nor 316 stainless steel is universally compatible with all chemical solutions. Consult the manufacturer chemical resistance guidance for the intended service.
Maintenance Checklist
- Confirm the original valve part number.
