Description
The purpose of the single flap valve is to provide a sealed air lock where the discharge above the valve is in a state of vacuum. The flap valve forms a major component in the regulation of material flow. RULA manufactures three distinct type of Flap Valves: - Single Gravity Flap Valve - Single Pneumatic / positioning Flap Valve - Double Motorised Flap Valve Acts as a shut-off mechanism in under pressure situations and to prevent a back draft going upstreamTypes of actuation
Pneumatically and electrical motor actuatedDesign Features
- Flap can be removed for maintenance without removing the complete valve - Flap sensitivity is easily adjustable via flap adjustment bolt - Material flow can be increased or decreased by adjusting the weights on the gravity arm - Both the flap as well as the insert are of wear resistant materials - The wear protected shut off disk is spring loaded to ensure an optimum sealing surface - The primary seal plate is wear protected and ground to a very smooth finish ensuring smooth and even operation at all times - Inspection covers allow easy visual inspection of all the wear and tear parts of the valve - Ceramic lined outlet spouts can withstand extreme wear - Control and Measuring of the material flowSpecifications
