Diffrential Pressure Control Valve

"The differential pressure controller is a straight-version proportional controller and works without auxiliary energy. The required nominal differential pressure can be continuously adjusted from 50 to 300 mbar. The adjusted set point can be read, locked and sealed. The nominal set point is factory preset at minimum. The required set point is adjusted by means of a hand wheel and secured against turning by the block ring. The impulse line (1000 mm) is included with the valve and is connected to a circuit regulating valve in the flow."
