Description
The VS214 safety valve is a full nozzle, full lift type. It features a high discharge coefficient (K=0.95) and is suitable for both gases and liquids. These direct-acting safety valves protect the operating conditions of tanks against overpressure. They can be mounted directly on the tank using suitable adapters, on the gas side of the safety block (BC32V), or on the gas manifolds of accumulator stations.
Construction
The body and dome are made of castings. The valve has a flat, metal-to-metal sealing seat. The spring counteracts pressure and dynamic fluid forces and ensures the valve closes after discharge. The calibration system includes a screw with a hexagonal head that compresses the spring and is screwed into the top of the valve. After calibration, the position of the adjustment screw is secured with a lock nut and sealed to the valve body.
