Self-reliance type pressure control valve

Automatic type regulator is USES the energy of medium to realize automatic adjustment of control valve, can be adjusted for pressure, temperature, flow, liquid level, can work in no electricity, no gas, to simplify equipment, save energy. Applied to petroleum, petrochemical, power, metallurgy, food, machinery, buildings. Automatic control of all kinds of gases, liquids and vapor pressure, stabilization (used before or after valve).
