Abstract:
A pressure regulator is configured for better accuracy and response times at higher inlet pressures. These configurations may integrate two-path control with a pressure-balanced plug. The two-path control may leverage a pair of pilot valves, one with a fixed differential pressure and the other with a variable differential pressure. In one implementation, the device is plumbed so that downstream pressure is sensed at both the actuator and the variable differential pressure pilot valve.
