Air Rams
The piston type air operated ram can be used in place of
the standard diaphragm air ram used on Liquip foot valves.
The plunger is pushed forward by a piston when air is supplied to the air inlet. The air in the cylinder is expelled through the exhaust port. The air ram assembly also has a sequential port the can be connected to other air rams in series.
A jacking screw is provided to allow manual opening of the valve in the event of air pressure loss (note that this does not fully open the valve).
