DK-LOK VH36 Series High Pressure Check Valve, 4,400 psig, 1" Female NPT Connections, SS316, VH36C-F-16N-3-S
Technical overview
DK-LOK VH36C high pressure check valve (VH36C-F-16N-3-S) is designed for backflow prevention in high-pressure service. This SS316 check valve is rated up to 4,400 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.
