Thread Pressure Relief Valve
The KOSEN Thread Pressure Relief Valves regulates the flow of the medium by controlling the opening and closing of the valve in the valve body, reduces the pressure of the medium, and adjusts the opening of the open and closed parts by the effect of the pressure after the valve, and keeps the pressure behind the valve in a certain range. The flow rate is selected for its path. When deciding the air pressure of valve, it should be greater than the maximum output pressure of 1.6MPa. The pressure relief valve is usually installed after the water separator, the oil mist device or the fixed value device before, and pay attention not to the inlet and outlet. When the valve is not used, the knob should be relaxed so that the diaphragm is often pressed and deformed to affect its performance.
