The 746 Safety Relief Valve incorporates a freely pivoting disc, which ensures correct alignment with the nozzle. The combination of top guiding, unobstructed seat bore, and full lift capability ensures the highest possible discharge rate, thus maximum plant protection.
The ‘conventional’ arrangement is suitable for applications where the built-up pressure will not exceed 5%. The conventional valve can also be used in systems where the superimposed back pressure is at a constant level (up to 80%).
We will set and test the valve to your requirements, and provide a pressure test certificate confirming this, prior to despatch.
