Description

DK-LOK VH36B high pressure check valve (VH36B-F-12N-10K-3-S) is designed for backflow prevention in high-pressure service. This SS316 check valve is rated up to 10,000 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.

Applications

  • Instrumentation impulse lines and gauge isolation
  • Hydraulic power units and high-pressure test stands
  • Sampling systems and utility distribution manifolds
  • Backflow protection for pumps, regulators, and transmitters
