Self-operated Micro Pressure Control Valve

Description

This serial self-operated micro pressure control valve is applicable to combustion systems of various industrial furnaces, due to its adoption of a balance single-seated valve and random adjustment of set value in service. Control of mixed specific discharges of two kinds of fule gas, sealed oil system for hydrogen-cooled generator set, petroleum products, and micro pressure automatic regulation of protective gas and heat-treating protective gas in oil storage tanks. In addition, it is suitable for automatic control of pressure reducing, stabilization, and relief of all industrial gases.

The Features of Self-operated Micro Pressure Control Valve

  1. The pressure setpoint can be adjusted on-site within the pressure adjustment range;
    2. The spring can be replaced according to the changes of requirements on-site so that the pressure adjustment range can be quickly changed within a certain range;
    3. Self-operated single-seat micro pressure control valve generally adopts rubber diaphragm as the pressure balance component. The change of upstream pressure does not affect the force of the valve plug, greatly speeding up the response speed of the valve, thus improving the control precision of the valve;
    4. The valve stem seal adopts a non-packing design, which greatly reduces the friction and the upper seal is absolutely reliable;
    5.The self-operated double-seat micro pressure regulator adopts a self-balancing double-sealed double-seat valve plug as the throttle piece, which is suitable for occasions with large valve diameter;
    6. The actuator adopts rubber diaphragm as the detecting component, which has a small resistance, quick response, high adjustment precision, and very micro pressure changes will be sensed through the diaphragm amplification;
    7.When the upstream pressure is >0.1 MPa, or the medium is corrosive to rubber, or it is a high-temperature medium, the pressure balance element and the actuator detection element can use metal bellows.
