instructions

Self operated pressure (differential pressure) regulating valve, composed of valve body, valve seat, valve core components and other parts, is an energy-saving product that directly relies on the pressure changes of the regulated medium to automatically regulate the pressure without the need for external energy. It can be used in pressure devices for non corrosive (up to 350 degrees Celsius) liquids, gases, steam and other media. Widely used in industrial sectors such as petroleum, chemical, metallurgical, and light industry, as well as urban heating and heating systems.

Product Features

Self operated pressure regulating valves do not require external energy and can work in places without electricity or gas, which is both convenient and energy-saving.
The pressure segmentation range is fine and intersecting with each other, with high adjustment accuracy.
The pressure setting value can be continuously set during operation.
For regulating the pressure after the valve, the ratio of the pressure before the valve to the pressure after the valve can be 10:1-10:8.
Rubber diaphragm type detection, with high precision and sensitive action of the actuator.
Adopting a pressure balance mechanism to make the regulating valve responsive and precise in control.
