Description: Pressure Relief Safety Valve opens to discharge the excess built up pressure on exceeding the set pressure. Once the excess pressure is released the valve automatically returns to the original position. The bronze internals (seat and plug) ensure that there is no leakage while in operation. The pressure range that is set could be changed by replacing the spring. It is available in 15NB, 20NB, 25NB, 40NB, 50NB sizes. The end connections are screwed BSPT type. The valve operates with maximum temperature required of 235?C and minimum blow off pressure of 17.5 kg/cm2.
