End Seal Rotary Valve Reduces Leakage

Model “ES” Rotary Feeder Valve

Model ES Rotary Valve 1 End Seal Rotary Valve Reduces Leakage

Model ES Rotary Valve

The Model “ES” (End Seal) Rotary Valve reduces air or gas leakage through the valve by approximately 50%

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 with peripheral sealing rings that press against the rotor shroud to reduce leakage through the valve.

The Leakage is reduce approximately 50%. The peripheral rings are continuously adjusted by using compressed are operate cylinders to provide the proper force.

With this design, you will get a more reliable feeding of product especially when handling products having a low bulk density and flow characteristics.

Model “ES” Rotary Valve Application Information

The Model “ES” (End Seal) Rotary Valve use for handling bulk materials having a low bulk density or on bulk materials handling systems using expensive inert gas in the process.

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 reduce approximately 50%. The peripheral rings are continuously adjusted by using compressed are operate cylinders to provide the proper force.

With this design, you will get a more reliable feeding of product especially when handling products having a low bulk density and flow characteristics.

The Model “ES” Rotary Valves are available with different rotor designs and wide variety of features to handle a wide range of process requirements.
