Air Cuff Shut Off Valve

AIR CUFF SHUT OFF VALVE

SAFELY STOP THE FLOW OF CONCRETE REMOTELY & REDUCE THE CHANCE OF HOSE WHIP

Air Cuff Hose Shut Off Valve manages spills and stops flow by collapsing the end hose from the outside using an inflatable bladder. This action also helps stop air from getting trapped inside the pipeline, which reduces the chance for hose whip. Controlled by either remote control or integration with the pump’s control circuit. For use on all boom trucks and placing booms.

WORKS IN TWO WAYS

AUTOMATIC: Connects to the concrete pumps control box to automatically stop the flow of concrete when the pump stops running. The Air Cuff automatically closes when pump is in OFF position and opens when the pump is in ON position or in reverse pumping mode for clean-out.

MANUAL: Operator has a remote control and can manually stop the flow of the concrete as needed.

QUICK TIP

One of the most common job site injuries relating to concrete pumping is hose whip. Hose whip happens when air becomes trapped, pressurized, & then violently releases at the outlet of a concrete pumping hose.

There are two common ways air gets trapped:

At the Hopper end, or inlet, of the concrete pump where air is inadvertently sucked in by the pump.
When the pump is turned off and, by the way of gravity, air is allowed to migrate its way into the pipeline.

Using the Air Cuff Shut Off Valve can prevent the latter of the two incidences regarding hose whip. By closing off the flow of concrete when the pump is turned off, the concrete in the later sections of the boom will not drain and allow air to be trapped inside the pipeline, therefore reducing the chance for hose whip.
