Description
The Young Industries, Inc. Model “ES” (End Seal) Rotary Valve is a Drop-Thru-Airlock Feeder Valve, either a “HC” (High Capacity) or “LH” (Low Headroom) or “SE” (Side Entry) model designed to reduce differential pressure leakage. Applications utilizing this valve see leakage reduced by approximately 50%.
The Model “ES” Rotary Valve works by using peripheral rings to seal against the rotor shroud and eliminate axial leakage. These peripheral rings are continuously adjusted with pneumatic cylinders to provide the proper force needed to reduce leakage.
Specifications
The Young Industries, Inc. Model “ES” (End Seal) Rotary Valve reduces air or gas leakage through the valve by approximately 50%. The Model “ES” basically eliminates the air leakage which occurs between the rotor edges and the end plates. Peripheral rings seal against the rotor shroud.
The Model “ES” Valve is a Drop-Thru-Airlock Feeder Valve, furnished as either a “HC” (High Capacity) or “LH” (Low Headroom) or “SE” (Side Entry) model with peripheral sealing rings that press against the rotor shroud to reduce leakage through the valve.
The Leakage is reduced by approximately 50%. The peripheral rings are continuously adjusted using pneumatic air cylinders to provide constant force on the ring.
With this design, you will get a more reliable feeding of product especially when handling products having a low bulk density and flow characteristics.
