  • Ordering Process

V230D/V231D self-acting pressure (differential pressure) regulating valve is composed of membrane (piston) actuator, valve body, valve seat, valve core, balance spring and other components. It is a kind of valve which can automatically adjust the pressure without external energy and only rely on the change of the pressure of the regulated medium itself. It is produced by introducing the controlled medium into the actuator according to the mechanical principle. The energy-saving products with constant or reduced pressure in front or behind the valve are suitable for the pressure control of non-corrosive liquids, gases, steam and other media. They are widely used in petroleum, chemical, metallurgical, light industry and urban heating and heating systems.


Product characteristics of self operated pressure (differential pressure) regulating valve


The greatest characteristic of self-operated pressure (differential pressure) regulating valve is that it can work in the place without electricity and gas, and the pressure setting value can be adjusted at will during operation.


This product has nominal pressure PN1.6, 2.5, 4.0; nominal diameter range 20 300 mm; service temperature 300 Various varieties available.
