Self-pressure regulating valve without additional energy, the use of the regulated medium's own energy as a power source introduced into the actuator to control the spool position, change the pressure difference between the two ends and the flow rate, so that the valve or the valve pressure stabilization. Self-pressure adjustment valve has the advantages of sensitive action, good sealing, pressure set point wave power is small, widely used in gases, liquids and media pressure stabilization or pressure relief stabilization of automatic control.
Self-pressure regulating valve does not need to add energy, the use of the regulated medium's own energy as a power source, the introduction of the actuator control valve spool position, change the pressure difference between the two ends and the flow rate, so that the pre-valve (or post-valve) pressure stabilization. With sensitive action, good sealing, pressure set fluctuations and other advantages, applied to gas, liquid and steam media pressure reduction and stabilization or pressure relief and stabilization of automatic control.
Self-operated pressure regulating valve does not require additional energy, can work in the place without electricity and gas, both convenient and energy saving, pressure segmentation range is fine and cross each other, high precision adjustment, pressure setting value can be set continuously during the operation of the valve pressure adjustment, the ratio of the pressure before the valve and the pressure after the valve pressure for The ratio of pre-valve pressure to post-valve pressure can be 10:1~10:8. With the rubber diaphragm type detection, the actuator has high measuring precision and sensitive action, and adopts the pressure balancing mechanism, which makes the regulating valve responsive and precise in control.
