Rotary Valve or Air Lock Valve for Food & Pharmaceutical industries

Rotary Valve or Air Lock Valve

Rotary Valve or Air Lock Valve:

A rotary valve is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. The common stopcock is the simplest form of rotary valve.

Despite its simplicity it offers several functional uses:- 

* Control product flow rate to the required rate (fixed or variable) 

* Maintain a gas pressure differential between the inlet & outlet (airlock) 

* Act as an explosion barrier 

* Act as a Flame Barrier 

* Act as a process isolator / barrier 

Typical Design / Feature Considerations

1. Housing Body & End Covers

2. Body Design

3. Inline Inlets 

4. Offset Inlets 

5. Housing End Covers

6. Blowing Seals 

7. Entrainment Boxes

8. Rotors 

Replaceable Blades 

These are by nature adjustable on assembly but should not be considered as being supplied to be 

able to adjust for wear as wear is never even, neither is it confined to the blades. It is however an 

economic way of introducing alternative materials of construction that may be required to satisfy 

the duty. 

Common examples include 

• Hardened steel; or alloy steel; or hard faced: for abrasion resistance 

• Scraper: to control product build-up on the housing bore and end cover faces when 

necessary 

• Flexible: (usually polyurethane or natural rubber) for fibrous or products containing large 

non friable particles 

• Plastic: product compatible or non-stick 

• Bronze or bronze tipped: for ultra close clearances 

9. Shaft Sealing 

10. Bearings

11. Drive Arrangements

12. Accessories

Common additions to rotary valves include: 

• Positive Overload protection (shear pin or proprietary torque limiting devices) 

• Non Rotation detection 

• Speed monitors 

• Safety switches on Easy Clean valves 

• Variable speed controls 

• Pressure regulators and flow meters for air purge seals 

• Rotor pocket purging equipment 

Applications:

Food & Pharmaceutical 

We provide customized rotary valve as per requirement of customer.
