Series 400 Pressure Relief Valves
The Series 400 modulating valve, with non-flowing pilot, incorporates an advanced design in pilot operated valves/400系列調節(jié)閥,帶非流量引導的,一體化的具有先進設計的可操作產品

The Series 400 modulating valve, with non-flowing pilot, incorporates an advanced design in pilot operated valves. Under process conditions, both pilot and main valve can be tight as high as 98 percent of set pressure. The main valve lifts proportionally, according to demand, restricting product loss to only that which must be relieved to prevent process pressure from exceeding the code allowance. The Series 400 is a no-flow, modulating action POPRV design suitable for gas, liquid and two-phase applications. The Series 400 represents the very best state of the art technology providing safety relief valve performance not possible from direct spring PRVs.
