ZZVP self force micro pressure regulating valve

Self force differential / micro pressure regulating valve is a kind of energy-saving pressure regulating valve without external energy, but only rely on the pressure change of the medium itself to achieve automatic adjustment and stable pressure difference as a constant value. He can use the industrial combustion furnace to control the good material, such as the flow ratio of gas and air, to achieve the ideal combustion. It is used in the seal oil system of the hydrogen cooled generator set to control the pressure difference between the seal surface and the hydrogen to ensure the reliable seal. The low pressure end of the differential pressure valve is the micro pressure valve.
