Reducing Check Valves

Engineered for reliability, these check valves provide precise, one-way flow control to protect sensitive equipment and ensure system integrity. By preventing backflow with a dependable seal, these valves are an essential component for any fluid or gas handling system where unidirectional flow is required. The check valves are offered in multiple housing and diaphragm materials to meet specific chemical compatibility and application needs. See the material spec sheet for more detailed information on each housing material.

Polypropylene, nylon, polycarbonate, gamma stable polycarbonate, or Kynar® PVDF housing
Viton™ FKM or silicone diaphragm
Pressure rating: 0.5 psi forward flow (crack); 1.9 psi secure back-pressure seal
