Imported Self-Regulating Pressure Reducing Valve
Section 1: Imported Self-Regulating Low-Pressure Control Valve Product Overview
Germany's VorwerkWODEAn imported self-contained low-pressure regulating valve is an energy-saving product that requires no external energy. It compares the pressure changes of the medium in the process pipeline with signals to balance the force of the regulated medium with the output force of the actuator, achieving stable pressure and differential pressure values. It employs a balanced single-seat valve, offering pressure stability, high precision, and good sealing, suitable for controlling small differential pressures.
Self-contained low-pressure regulating valves are suitable for controlling the mixture ratio flow of two fuel gases in various industrial furnace combustion systems or for use in the sealing oil system of hydrogen-cooled power generating sets. Additionally, they can be used for automatic control of pressure reduction, stabilization, or relief for various industrial gases. They allow for adjustment of set values during operation. Therefore, they are applicable in various scenarios, such as automatic micro-pressure regulation for fuel gases in industrial furnace combustion systems, intermediate products of petroleum, or protective gases in oil storage tanks, as well as for protective gases in heat treatment processes.
