Self-operated pressure control valve

When the pressure in the valve before and after the introduction of the implementing agencies on both sides of the gas chamber, the self-pressure control valve can control a constant differential pressure across the control valve can also be installed in the pipe on the pressure differential across the orifice plate introduction of pneumatic diaphragm actuators on both sides of the gas chamber, composed operated flow control, or otherwise self-differential pressure control valve flow control flow detection.shut off solenoid valve
Self-operated pressure control valve. In the figure, the flow rate setting adjustment is used to adjust the flow resistance. Setting adjustment is used to change the initial spring preload adjust the differential pressure set value. The differential pressure is the comparison of the two membrane actuator output thrust, only with a diaphragm actuator. When the pressure measuring point signal is derived from the same pipe is installed on both sides of the orifice plate can be used to control the flow.mini solenoid valve
