The series of self operated micro pressure control valve produced by TangoValve Group is an energy-saving product without external energy. The pressure change and signal of the medium in the process pipeline are compared to make the force of the regulated medium and the output force of the actuator balance, so as to achieve stable pressure and differential pressure.
Owing to its adoption of seated valve and random adjustment of set value in service, this serial self-operated micro pressure control valve is applicable to combustion systems of various industrial furnaces, control of mixed specifc discharges of two kinds of fuel gas, sealed oil system for hydrogen-cooled generator set, petroleum products, and micro pressure automatic regulation of protective gas and heat treating protectivegas in oil storage tanks. In addition, it is suitable for automatic control of pressure reducing, stabilization and relief of all industrial gases.
