DEMO: RNHC Rotary Valve
High Capacity - Pellet Metering
Model RNHC
When your application demands precise pellet metering, Young Industries Model RNHC Rotary Valve delivers. The eight-vane rotor, ensures a constant two-blade seal for minimal air or gas leakage. And the precision-machined housing guarantees a tight fit, making it ideal for applications requiring pressure or vacuum sealing.
The Model RNHC Rotary Valve is your solution for the high-capacity metering of pellets and prills (1/16" to 1/4"). Its unique vertical drop-through design feature a pellet-flow inlet throat and rotor that virtually eliminates pellet clipping for a smoother, more consistent flow and reduced downtime.
Features & Options
The RNHC Rotary Valve delivers the control you need for variable speed and rate applications, ensuring accurate metering even in challenging environments. Our innovative inlet throat deflector guides pellets smoothly into a secondary set of rotor pockets, preventing shearing and jamming.
We offer a range of customizable features and options, allowing you to tailor the RNHC Valve to your exact needs. Whether you require high-pressure capabilities, specific materials of construction, or specialized coatings, we've got you covered.
And like all our rotary valves, we can customize the RNHC for high pressure, high temperature, or low leakage rate conditions. Because at Young Industries, special is our standard.
