Servovalve, Hydraulic-Description. A hydraulic servovalve is a servo (see Servo, Hydraulic â Description) with a device (either flapper nozzle or jet pipe) used to position the servo. The term electrohydraulic servovalve is often used because servovalves are controlled through an electrical signal.
The function of a Cycle Stop Valve (CSV) is to: (1) To provide variable flow and constant pressure control more economically than VFD systems with a high degree of reliability. (2) To replace large pressure tanks and water towers. (3) Provide minimum flow required to cool the pump and/or motor.
