M Series Chainwheel

M Series Hammer Blow Impact Actuator

The M Series is designed for situations where a manually operated valve (MOV) is difficult to open / close due to weather conditions or infrequent use, or where the valve is too large to easily operate with a standard chainwheel.  It is particularly suitable for overhead valves.

The M Series operates by delivering a controlled hammer blow, and can be used without fear of damage to the valve.

There are two styles available: the handwheel style for ground level operation, and the chain style for above ground operation.  Both styles have the option to be either clamp on or direct mount.  The direct mount style comes with an adapter plate to replace the existing handwheel.
