Pressure regulating valve for flow capacity

Description

Self-operated pressure regulating valves are divided into three series of self-operated pressure, differential pressure and flow regulating valves. The self-operated pressure regulating valve is divided into two categories: front and rear of the valve according to the position of the pressure point. When the pressure point is in front of the valve, it is used to regulate the constant pressure before the valve; when the pressure point is behind the valve, it is used to adjust the pressure behind the valve to be constant.

When the pressure downstream and upstreams is introduced into both sides of the air chamber of the actuator at the same time, the self-operated differential pressure regulating valve can adjust the pressure at both ends of the regulating valve to be constant, or the pressure difference at both ends of the orifice plate installed on the pipeline can be introduced into the membrane to perform the operation. On both sides of the air chamber of the mechanism, a self-operated flow regulating valve is formed, or a self-operated differential pressure regulating valve is used to realize the flow regulation after the flow is detected in other ways.


Features

1. Self-operated pressure control valve does not require additional energy, and can work in places without electricity and gas, which is convenient and saves energy
2. The pressure segment range is narrow and intersecting with each other, and the adjustment accuracy is high;
3. The pressure setting value can be continuously set during operation;
4. To adjust the pressure behind the valve, the ratio of the pressure before the valve to the pressure after the valve can be 10:1 ~ 10:8;
5. Rubber diaphragm type detection, the actuator has high measurement accuracy and sensitive action;
6. The pressure balance mechanism is adopted to make the control valve respond sensitively and control accurately.
