Product description:

Direct acting self-acting pressure (differential pressure) control valve, the valve body, seat, valve components and other components, is a kind of without external energy and only rely on the pressure of the media to be adjusted automatically adjust the pressure of energy savings Type products, can be used for non-corrosive (maximum temperature of 350 ℃) liquid, gas and steam and other media pressure control device. Widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors and urban heating, heating systems.
