DK-LOK V33C Series Poppet Check Valve, 3000 psi, 1/2" Tube OD Connections, SS316, V33C-D-8T-1/3-S
Technical overview
The DK-LOK V33C series poppet check valve is built to prevent reverse flow and support stable one-way operation in process tubing and instrumentation circuits. This fixed-cracking configuration uses DK-LOK tube fitting end connections and a spring-loaded poppet with FKM sealing for consistent shutoff. SS316 construction suits industrial fluids in chemical processing, power generation, and oil and gas applications where dependable backflow protection is required.
