Hydraulically-operated valve 750-67

floatlevel controlin-line

Product overview
Hydraulically operated control valve that controls reservoir filling and reservoir level. Reservoir filling is governed by a hydraulically controlled modulating vertical float that maintains a constant water level regardless of fluctuating demand. Suitable for intake or outtake configurations depending on the application.
