A small internal pressure sensor monitors the output pressure and a digital or analog controller adjusts the timing of the servo valves to maintain the set point. Servo electronic pressure regulators eprs work by using a push valve and a vent valve to maintain the outlet pressure at the desired set point.

Type 3210 and type 3220 analog enclosure regulators from marsh bellofram corporation.
Servo pressure regulator. A pressure regulator is a control valve that reduces the input pressure of a fluid or gases to a desired value at its output. The 959 regulator is a high pressure tied diaphragm regulator that is designed to provide shut off of corrosive or hazardous gases if a leak occurs and is capable of controlling a broad range of gases and liquids with process proven field reliability. Youre looking for a pressure regulator to do this. Airline equipment pressure regulators. The prg200 series is a high precision multi stage regulator which provides the highest level of regulation accuracy and repeatability availablea stainless steel measuring capsule is used as a sensing element to activate the high gain servo balanced control mechanism in which the. Its the same idea as your valve connected to a servo scenario but regulators have a spring loaded ball inside them to control the pressure whereas a valve just opens an orifice. How electronic pressure regulators work. Regulators are used for gases and liquids and can be an integral device with an output pressure setting a restrictor and a sensor all in the one body or consist of a separate pressure sensor controller and flow valve. An electromechanical actuator operated pressure regulator for supplying control pressure for a diaphragm operated gas control valve the actuator also operating an on off control valve for the gas valve. Pressure regulators from smc have been updated to the new urban white base color for a clean modern look. A passageway including a pressure adjusting device for supplying a minimum gas valve output pressure extends from the downstream side of the on off valve to the gas valve outlet. 05000 to 120 psi. The tr servo pneumatic pressure control system is an all in one electronic pressure regulator ep ip that converts a voltage or current input into a precise proportional pressure output. Type 3210 single loop and type 3220 double loop electro pneumatic servo pressure controllers incorporate two solenoid valves and an internal pressure sensor for increased sensitivity and accuracy housed within a. A servo valves is a device that meters the flow of oil in response to an electrical input signal or command to control position velocity pressure or force in some type of machine or device.
Any home improvement store should have them for under 10. The pressure drop across the regulator has been reduced to create a more efficient unit with a maximum set pressure of 100 psi.
