Airslide Valve
Based on the Barrel Control valve, this comes complete with an integral airslide and vee-notch to control the vlow of cement between airslides.
The airslide material is a porous heavy duty polyester with a custom stainless steel protective mesh, designed to aerate the cement so if flows across the base of the valve.
Fine control is by using the vee notch shape in the barrel, which, coupled with the 4-20mA pneumatic actuator, allows the downstream airslide bed height to be adjusted.
