Rotary Valves | Extensive Range

Supplier: Bulk Materials Handling

These units are made to the same exacting standards as the extra heavy but are manufactured for dust collection and silo discharge to atmospheric conditions and lighter duties.

These units are signified by the “0” being replaced by a "1" i.e. BMH RV 201.

Currently under development we have a 301 & 40 Valve capacities-Chart to calculate valve size, however please refer to BMH for confirmation.

Extra Heavy Duty Rotary Valve

Casing - Grey  260 MPa. Cast Iron, stress relieved and diamond bored to close tolerances. Casing inlet has a 3 degree offset to give a scissors action to the valve. Casing wall drilled and tapped for vent connection.
  
End Plates - Grey 260 MPa. Cast Iron, castings stress relieved and having bearings mounted in outriggers.
   
Bearings - Deep groove, self aligning ball bearings with double seals are mounted outboard of the gland packing. The gap separates the bearing from any gland leakage and enables the packing to be easily changed.

The bearings have spigoted housings allowing us to set fine clearances between the rotor and the bore. The spigot also allows a bearing to be removed and replaced without the need to reset the rotor tip clearances.
    
End Plate Seals - Compression gland type with three square section packing rings and a lantern ring. The end plates are drilled and tapped for grease and/or compressed air injection to the glands.
   
Rotor - Shaft manufactured from carbon steel, with a step down at the seals then stepped down again at the bearings. The rotor blades are jig welded to the shaft and machined with a fine clearance to the housing.
   
Rotor Tips - Machined all over, bolted on and adjustable for wear, tips have a machined chamfer to provide a cutting edge against the cast housing. Rotor tips are supplied in mild steel as standard. Alternative materials are hardened and ground tool steel, stainless steel, brass and a special oil filled nylon.
   
Cutter Blades - When tool steel rotor tips are used, hardened blades are bolted to the inlet and outlet of the valve body. These, together with a larger gearmotor, enable the valve to handle stringy and fibrous materials, such as paper and woodchip.
