Applications & Industries
Thanks to its highly modular design, our products can be adapted for virtually all types of product characteristics and applications:
- Metering device
- Airlock, explosion containment, flame barrier and system isolation
- Suitable for gravity, positive pressure and vacuum conveying systems
- Powders, granules, pellets, grain, feed and chips
The RotaVal products are used in many different industries, such as dairy, food, pharmaceutical, minerals, plastics, power plants and others.
Rotary Valves - Heavy Duty HDM
The HDM is our general purpose rotary valve line, able to cover many standard applications.
The HDM rotary valve has been designed using finite element analysis to make the housing even more robust.
Rotary Valves - Heavy Duty Cleanable HDMC
The HDMC rotary valve is a cost effective solution based on the HDM valves for occasional cleaning of the valve internal.
The non-drive end cover can be quickly removed to gain access for cleaning which can be carried out by plant operators without the need for special tools.
Various standards of finish are available to suit most hygienic applications.
Rotary Valves - Heavy Duty Fast Clean HDMF
The USDA Dairy Accepted HDMF rotary valve is based on the HDM valve and provides users with increased productivity through a design that realises minimal down time for frequent cleaning of valve internals.
The non-drive end cover incorporates the new Rota-lign™ bearing assembly. This is a self-centralising rotor design to aid dismantling and re-assembly. So cleaning can be carried out by plant operators without special tools.
Should full access be required there is also an option for drive end cover removal.
A robust construction makes this fast clean range suitable for use in nearly all types of industry and with no special tools needed to gain access to the valve internal, it's very operator and process friendly.
Rotary Valves - Extra Heavy Duty EHDM
The RotaVal EHD units have been well-proven over many years and are widely used in discharging under adverse pressure conditions, materials such as cement, PFA, granite dust, silica sand, mineral powders etc.
- Replaceable internal components allow for on-site refurbishment.
- Standard valves manufactured in cast iron / SG iron / carbon steel construction with round flange. To further enhance durability replaceable body liner can be hard chromed or ceramic coated.
- Rotor shaft sealing options include various types of gland packing, mechanical seals, air or grease purge.
NOTE: Service life of these valves will vary according to the service conditions prevailing. Selection must be undertaken with care and system conditions where possible adopted to ensure maximum service life.
Your advantages (depending on version)
- Highly configurable to suit virtually all applications
- Once extracted from the housing, the rotor can be rotated for cleaning whilst still attached to the end cover
- Tapered bore and guide rails provide scratch free rotor extraction and insertion
- Parallel rail design with a support tray to rest motor on in hard to access places
- Valve housings are individually pressure test for 10bar(g) explosion and flame containment requirements
- Unique replaceable parts for wear including rotor shaft, line, blades, end discs and sleeves
- USDA dairy accepted (HDMF)
