Product Details

Product Overview
The direct acting self operated pressure regulating valve is composed of components such as the valve body, valve seat, and valve core. It is an energy-saving product that automatically adjusts the pressure without the need for external energy and only relies on the pressure changes of the regulated medium. It can be used as a pressure control device for non corrosive (temperature ≤ 350 ℃) liquids, gases, and steam. Widely applicable to industrial sectors such as petroleum, chemical, metallurgy, light industry, and urban heating and heating systems.
