A direct acting Safety Relief Valve intended for gas, vapour, and liquid service. The Valve opens in gas or vapour service as full-lift Safety Valve. In liquid service the Valv3e will open in proportion to the rise in over pressure and will require a high over pressure to open fully. Depending on construction. HPLOCK Safety Relief Valves are referred to as Conventional or Balanced Safety Relief Valves. |
