Abstract
A valve for a pneumatic dispenser, the dispenser comprising a handle with an actuation arrangement for selectively applying pressure to a respective one of the front and rear chambers on either side of a piston coupled to a rod for applying a dispensing force, thereby controlling movement of the rod. The valve is provided with a body and first and second moveable members moveable relative to the body. The valve can be arranged as a space saving five port valve instead of two three port valves for use in the disclosed dispenser and can be arranged to provide a fail safe mechanism if both valve members are actuated concurrently. A dispenser comprising a stock portion and a cylinder secured to the stock portion is disclosed. Pressure is supplied to the rear chamber of the cylinder from the stock portion through its front chamber and the piston moveable inside the cylinder.
