Pressure Safety Valves

It can also be advantageously used for most other applications on gases vapours, liquids and saturated steam systems involving small discharge capacities. The SRV12 Series valves are specially designed for steam but can be used on, liquids and gas as well. The valves are designed as per API 526 and meet the requirements of ASME Sec VIII-Division. SRV12 Valves are offered with IBR Certification Form III-C. The valves have a solid nozzle screwed into the valve body and is fully guided at the upper section of the valve body, increasing the strength of the valve assembly. Specially designed disc holder ensures full lift within 5% increase of pressure above the set pressure value. i.e. Over-pressure of maximum 5%. Blowdown of a maximum of 5% is achieved in this design. Superior lapping of the seat area ensures a high level of leak tightness at seat. Disc lifts above 14 of nozzle diameter which ensures that the certified flow of the safety valve is discharged. The Spring is selected and assembled with great care so that the valve operates precisely and a good leak tightness is achieved.
