POWER AT YOUR CONTROL
The ELECTRIC ON-OFF model of the 800 Series Control Valve is a hydraulically operated sleeve type valve with an electric solenoid control.
The flow through the valve is controlled by a rubber sleeve which is actuated by hydraulic pressure. The valve is either in the fully opened or the closed (shut off) position when operated electrically. When the selector is pointed to the “AUTO” position then the electric solenoid is used to automatically open or close the valve. The 3-way electric solenoid must be energized to open the valve and de-energized to close the valve. Pointing the manual selector handle to “OPEN” or “CLOSE” will override the “AUTO” control. The manual selector can be used to hold the valve partly open by opening the valve part way and then pointing the selector handle midway between “OPEN” and “CLOSE”.
