Britton Procol standard fabricated rotary valves are designed for use with low density products such as wood shavings, wood dust and textile fibres. They provide an economic solution for applications which require high feed rates of low density products.
The valve body is fabricated from sheet steel and fitted with a 6 blade rotor having replaceable polyurethane or insertion rubber blades. Drive is by a worm geared motor flange mounted from the valve endplate and direct coupled to the rotor drive shaft. Capacities for standard fabricated rotary valves are identical to the equivalent cast Rotary Valve.
Special valves are available for use with moderately aggressive products such as fibreglass strands or filled WC granules. For these applications drive is by a worm geared motor the valve body is fabricated from flange mounted from the valve abrasion resistant steel and the rotor endplate and direct coupled to the has special rubber blades. Fabricated rotary valves are available in standard sizes as shown in the data sheet and also in none standard sizes up to a maximum rotor size of 1000mm x 2500mm long.
