SAFETY AND RELIEF VALVE

Designed to relieve overpressure in a piping system containing compressible or incompressible fluids.
It is the preferred solution for automatically relieving overpressure in boilers, pressure vessels or other systems when the pressure and / or temperature exceeds the allowable limits.
Design in accordance with ASME PVC Section VIII Div. 1, as well as ASME B16.34 design requirements.
Conventional style steel safety and relief valves with bellows, soft seat and open hood classes: 150 x 150, 300 x 150, 600 x 150.
Portable steel safety and relief valve classes: 2000 and 5000.

In-plant calibration as per customer's requirements.
Carbon or stainless steel manufacture.
Design with a fixed secondary orifice and a ring that can be adjusted to reduce the forces raising the seal disc for full seal disc lift.
Manual lifting mechanisms are available for maintenance or system verification purposes.
Cast iron refurbishing qualified in accordance with ASME B16.34 radiographic requirements.
