Pressure Relief Cast Steel Safety Valves

Our Pressure Relief Safety Valve is designed as a Pop-Up type valve. On exceeding the set pressure, the valve opens to discharge the excess built-up pressure. After relieving the excess pressure, the valve automatically returns to its original position. The stainless steel internals (Seat & Plug) ensure that there is no leakage while the valve is in operation. By replacing only the spring, it is possible to change the set pressure range.
