Tecofi » Knife Valves » Chainwheel - DN 50 to DN 1200

Chainwheel Knife Valves are used where a manually operated valve is required but, generally, where the valve itself is located too high above an operator floor for a handwheel to be reached. 

The chain (similar to those used on roller shutter doors) is wrapped around the outside of the chainwheel and then welded into a continuous loop.  Pull one side of the chain loop and the chainwheel screws the spindle and gate up into the open position, pull the other side of the loop and the chainwheel forces the gate closed.

Our VG Chainwheel Knife Gate Valves share the same parts as our solidly designed rising spindle handwheel operated valve but with the handwheel replaced by a cast iron chainwheel.
Because the operator can be remote from the valve these are often fitted with end of travel switches to indicate the position.  All VG Knife Valves are supplied with the supports pre-drilled to accept our ranges of indicator switches.
