DK-LOK VH36 Series High Pressure Check Valve, 6,000 psig, 1/4" Tube OD Connections, SS316, VH36A-D-4T-3-S
Technical overview
DK-LOK VH36A high pressure check valve (VH36A-D-4T-3-S) is designed for backflow prevention in high-pressure service. This SS316 check valve is rated up to 6,000 psig and uses a fixed nominal cracking pressure of 3 psig to open and allow forward flow while closing automatically when pressure reverses. The valve is suitable for compact panel or inline installation where reliable sealing, repeatable opening pressure, and corrosion resistance are required.
