INTRO: Rotary Valves - Model ES - End Seal
End Seal
Model ES
The Young Industries Model ES (End Seal) Rotary Valve is your solution for dramatically reducing differential pressure leakage. Available in our popular HC (High Capacity), LH (Low Headroom), or SE (Side Entry) models, the ES Valve cuts leakage by approximately 50%, ensuring optimal process efficiency and control.
How does it work? The ES Valve utilizes peripheral rings that seal against the rotor shroud, eliminating axial leakage. These rings are continuously adjusted with pneumatic cylinders to maintain the perfect sealing force.
Features & Options
The Model ES Rotary Valve isn't just about reducing leakage—it's about optimizing your entire process. We've packed it with features designed to handle even the most demanding applications, from extreme temperatures to abrasive materials.
The Model ES Rotary Valve virtually eliminates air leakage between the rotor edges and the end plates. This translates to improved process control, reduced energy waste, and increased productivity.
Whether you're handling low-bulk-density materials or products with challenging flow characteristics, the ES Valve provides reliable feeding and superior performance.
