Dual Valve
Technical Data
The Dual's operates on the discharge side of the pump. As the flow through the pipeline starts or stops, the ball automatically rises or falls, opening or closing the valve. The handwheel is there to lock the ball in position. The handwheel can be used to isolate, but with back pressure. The Dual valve can work in the horizontal and vertical position.
Actuators
All types of actuators can be fitted, electric, gearbox,
hydraulic, pneumatic and handwheel.
Fully Automatic Operation
Fully open position
With the handwheel wound up the ball lifts completely out of the flow.
Closed, or reflux position
As the flow reduces and the pressure drops the ball falls and positively locates in the seat.
