brass threaded safety valve
1.Working Principle
The series of valve is used in bolier,pressure vessel and other pressure equipment that working temperature ductile cast iron ≤300℃,WCB ≤425℃ & applicable medium is steam,air,water and noncorrosive medium etc.as a overpressure safety equipment.
When the medium pressure goes up adjustable data automatically,then let them all ,so as to keep the pressure from going up,and when the pressure goes down another adjustable data,the valve will close automatically,so as to prevent the medium from leaking.
