High Capacity

Model HC

Our Model HC (High Capacity) Rotary Valve is a drop-thru airlock feeder valve with the lowest air or gas leakage in the industry. Not to mention a significantly larger throughput capacity when compared to other rotary valves. As a result, the Young Industries Model HC provides superior performance and reliability in a wide range of bulk materials handling applications. All of this adds up to complete peace of mind and low cost of ownership.

The Model HC Rotary Valve is engineered with a larger diameter rotor and unrestricted inlet and outlet. This full size opening design results in “straight through” rotor pocket filling and discharging. With this design, you get more reliable product feeding, especially when handling materials with poor flow characteristics.

Features & Options

When your process demands precise control, the HC Rotary Valve delivers. The Model HC Rotary Valve is used to prevent air or gas loss between two different pressure zones while allowing dry solids material to pass from one pressure zone to the other. We’ve packed it with features designed to meet the most demanding applications, from pressure and temperature extremes to handling a wide range of bulk materials. Every detail is engineered to keep your process running smoothly, reliably, and cost-effectively.

Standard drive and accessories include a parallel shaft gearmotor, sprockets, and drive chain enclosed in an OSHA compliant guard.
