Two-way flap type diverter valve

two-way-flap-type-diverter-valve

Designed to meet the pneumatic conveying industry's requirement to route powder, pellets or granules from a product source to two receiving points with minimal pressure drop. The RD diverter valves find their application in the conveying of non abrasive, free-flowing products. RD type diverters are designed to suit simple two-way diversion in pneumatic conveying systems operating at pressures up to 1 bar.

Valve features
Compact design/construction
Small divert angle -22,5°
Low pressure drop – minimal transition effect
Smooth internals  - no lodgement points
Simple access and maintenance
Dust enclosures up to 1 bar
Wide selection of materials
Pneumatic and/or manual actuation
Available in 8 size ranging from 50 up to 300 mm

Diverter valves type RD 

Construction
The RD diverter valve is constructed so that the internal synthetic flap always seals against the bore of the housing. The flap components and actuating cylinder are connected to the drive shaft which in turn is integrated into the valve body.
The RD diverter consist of a robust body manufactured in two sections, split at a centre flange for ease of access to the internal sealing flap. Due to the cone transition at the inlet, the sealing area within the cone forms a complete parabola and therefore an efficient internal seal can be maintained without resorting to sealing ledges. With no lodgements point and a gradual transition from one line into the other it limits turbulence and pressure drops.


Execution
Choice of materials can cater for the majority of applications. Materials available are: cast iron, stainless steel, aluminium or chemically nickel plated. By coating the body and internal components mildly-abrasive products can be handled. Actuation can be handled manually or with pneumatic air cylinder (direct- or in-direct driven). All diverter valves can be executed with limit switches to indicate open/closed conditions. RD type diverter valves are available in 8 sizes ranging from 50 up to 300 mm with circular connection flanges.
