Overview of Imported Self-Regulating Pressure Differential Valve

Germany's VorwerkWODESelf-contained differential pressure regulators are mainly composed of a control valve, an actuator, and a spring set at a specific pressure. They come in two forms: differential pressure rising valve closed and differential pressure rising valve open. They operate without external power, utilizing the pressure changes of the medium in the process pipeline for comparison with the signal. This ensures that the force of the regulated medium is balanced with the output force of the actuator, thereby stabilizing the pressure and differential pressure values. Self-contained differential pressure regulators are suitable for non-corrosive liquids, gases, and steam, and can be used in various oil products, chemicals, and gas seals for liquid storage tanks.

Features of the imported self-contained differential pressure regulating valve:

Self-contained differential pressure regulating valves require no external energy, utilizing the pipeline's own pressure for adjustment, saving energy, and featuring a simple system with low costs. They are suitable for environments without electricity or gas, eliminating the risk of external energy sources. Operation is straightforward, involving simply turning the adjusting nut for setting. They offer the advantages of pressure balance and high sensitivity. Through component combinations, they can be used for various control configurations!

Operation Principle of Imported Self-Regulating Pressure Differential Valve:

Self-contained (pressure rise valve closed) control valve, consisting of a self-regulating valve, actuator, and a spring set at a specific pressure. Suitable for non-corrosive liquids, gases, and steam, for pressure differential control within system piping. The control valve closes when the pressure differential increases.
