Product Description
FREE-VALVE’s spring type low lift closed safety valve(flange type) is based on the change of the media pressure at the inlet port and the spring pretension force to automatically open and close the valve disc.When the lifting force of the medium pressure (internal pressure) is higher than the spring pretension force, The valve disc overcomes the spring pretension force to open automatically, and the safety valve internal pressure drops after discharging excess media,and due to the action of spring force, when the internal pressure of safety valve drops to a safety value, the valve disc automatically closes,discharge stop, which does not need to manually reset.
Features
1,simple structure, good sealing performance, accurate opening pressure, re-seating pressure difference is small, easy adjustment,etc.
2, The seat is a Valenozzle-type , the speed of sound is reached when steam flows through the seat outlet, discharge coefficient is large.The seat sealing surface weld tungsten carbide alloy, wear resistance, long life.
3, The sealing surface of valve disc is hardened to improve wear resistance and anti-flush resistance.
4, Adjusting the adjustment nut, adjust the spring compression, the valve can be very convenient, very quickly to obtain accurate adjustment pressure.
