Threaded safety valves are pressure relief valves with screwed inlet or outlet connections, commonly used on compact pressure vessels, compressors, air receivers, water systems, small process skids, utility steam lines and equipment where threaded piping is specified. They are often requested as threaded pressure safety valves, threaded safety relief valves, NPT safety valves, BSP safety valves or 2-inch threaded safety valves.

Why threaded connection details matter

A threaded safety valve is not selected only by thread size. The connection form, thread standard, pressure rating, set pressure, required relieving capacity, medium, temperature, material and installation direction all affect whether the valve can protect the equipment correctly.
