are used in any situation where a low cost, reliable actuated valve
is required. Whether you need a valve firing open and closed
all day or a simple remote actuation solution these are hard to
The linear movement of the gate of a Knife
Gate Valve makes it very easy to actuate with a simple
pneumatic cylinder (sometimes called a pneumatic ram). Apply
air to one cylinder port and the valve opens, apply it to the other
and it closes - Simple. Even easier if you take it pre-fitted

All VG Pneumatic Knife Gate
Valves are fitted with a cylinder sized, designed and
built specifically for the VG valve - no separate adaption plates,
no separate clevis. The base of the cylinder is a single
aluminium casting bolted directly to the valve support plates, the
piston rod is stainless.
Every valve is pre-drilled and tapped for Guards, End
of Travel Switches and Solenoid Valve. This is true even for
manually operated valves so converting from manual to pneumatic
couldn't be easier.
