How to Better Control a Concrete Pour

Discover the advantages that an EQV valve offers while pumping.

The Putzmeister Pipe Technology EQV valve, also known in the industry as a Squeeze Valve, Hose Shut Off Valve, or Air Cuff, prevents concrete spillage contaminating the job site and helps ensure a safer, controlled pour by quickly stopping the flow of concrete.

If one does not have an EQV valve, the alternative would be to physically fold the hose or stop the flow of concrete with a mechanical device, both of which can be unsafe and unreliable. The EQV valve is robust and flexible and is designed without any metal parts, minimizing the risk of injuries.

The valve connects to the concrete pump’s control box and operates off the truck’s air supply system. It opens or closes in a matter of seconds, opening automatically when the pump is started and closing when it is stopped. This makes it easy to use and a reliable method of stopping concrete flow.

An EQV valve is a great option to have when pouring walls and columns, when precision is essential. It is also useful if a pour needs to be topped off with just a small amount of concrete.

The EQV valve can be used with all concrete pumps, and retro fit kits are available to integrate necessary functions into pumps already in service. The Putzmeister Pipe Technology EQV valve can be used with end hose sizes 4″ (100mm) – 5″ (125mm). The valve meets or exceeds Concrete Pump Manufacturer’s Association safety standards.
