Self-operated differential pressure regulating valve-Control valve series-调节阀厂家-上海冠环阀门制造有限公司

Product overview

Self-operated differential (micro) pressure regulating valve is a kind of energy-saving product without external energy, using the process pipeline medium pressure change and signal to compare, so that the force of the regulated medium and the output force of the actuator balance, in order to achieve stable pressure, differential pressure value. In operation, the set value can be adjusted arbitrarily. Therefore, it is suitable for all kinds of industrial furnace combustion system fuel gas, petroleum products in process or oil storage tank protective gas and heat treatment protective gas micro-pressure automatic regulation and other occasions.

Product characteristics
1, the micro-pressure control valve does not need additional energy, the use of process pipeline medium pressure to adjust itself, both convenient and energy saving;
2, the pressure segment range is fine and cross each other, the adjustment accuracy is high, the pressure setting value can be set continuously during operation;
3, adjust the pressure behind the valve, the ratio between the pressure before the valve and the pressure after the valve is 10:1~10:8;
4, rubber diaphragm type detection, the actuator detection precision is high, sensitive action;
5, the use of pressure balance mechanism, so that the control valve responsive, accurate control.
