The easy-slide rotor support is an optional accessory for all sizes of de-mountable convey and drop-through rotary valves for hygienic and sanitary applications. It safely supports the rotor and non-drive end-plate when they are removed from the valve bore, and keeps them precisely aligned for reassembly.

Rotor and end-plate are mounted to a hinged, slide-rod carriage assembly supported by precision linear bearings. End-plate only, or complete rotor and end-plate assembly can be removed in one operation, without tools, and turned to one side for full access to all product-contact surfaces.

Design speeds and simplifies inspection, cleaning and maintenance. It's ideal for applications where the valve requires frequent dis-assembly or is not easily accessible.
 
Reduces risk of damage to precision-machined rotor and body bore for optimum valve performance. 

• Eliminates need to "man-handle" heavy components. Reduces risk of operator injury
• Assures precise rotor alignment in body bore for reassembly
• Can be retrofitted to standard de-mountable rotary valves
• Heavy-duty construction features hard-chrome slide rods and precision linear bearings to maintain critical tolerances
• Maintenance-free design with permanently lubricated sealed bearings and wear-resistant components
• Available in left or right-hand configurations and a variety of materials and surface finishes to match rotary valve specifications
• ATEX rated valves are available for use in hazardous zones

The all new large inlet rotary valve series has been developed for typical cyclone or dryer applications where the inlet performance is critical to the process. In such applications, the product must flow freely into the valve where the convey through (CV) system can transfer the product away.

The new valves are available in a range of sizes from 200mm to 300mm (CV500) and 300mm to 350mm (CV750). The Generation 3 Rotor Detection System is also available on all models in the series.

Specifications include:

Size:

• 14” (350mm) ANSI flange inlet
• 2.5” – 5” process connection ports
• 2 sizes available; 12L per revolution (500 model), or 23L per revolution (750 model)

Rotary airlock valves (also known as rotary feeders or rotary valves) are widely used in various industries for controlled feeding and discharge of bulk materials while maintaining an airlock between different pressure zones. Here are the main applications of rotary airlock valves:

Here’s a detailed technical overview and specification sheet for your 8-inch Rotary Airlock Valve made of SS304 with round flange, geared with a Bonfiglioli W63 gearbox and powered by a 0.75 kW Hindustan IE2 motor. This design is built for rugged use, suitable for materials with high bulk density (1600 kg/m³), and aligned with ANSI standard drilling.
General Function:

• Maintain pressure differentials between two environments (e.g., a high-pressure vessel and a low-pressure conveyor).

• Regulate and meter the flow of dry powders, granules, or pellets.

• Prevent air or gas leakage during material transfer.
