Rota Val is a leading designer and manufacturer of Rotary Valves and Diverter Valves and associated equipment for bulk industries throughout the World. The company's wide range of rotary valves includes innovative yet competitively-priced standard rotary valves for applications in food, pharmaceutical, chemical, mining and many other process sectors. More unusual or demanding needs are met by Rota Val's bespoke design, development and manufacturing service for special rotary valves based upon its vast experience in handling all types of solids from fine dusts and abrasive materials to fragile products such as pasta and breakfast cereals . Whatever your rotary valve needs, a full complement of in-house resources ensures that customers receive very high standards of service before, during and after installation. Accredited to ISO 9001 : 2000,
Rota Val Rotary Valves are ATEX 94/9/EC certified and available with EC type Examination Certificates for 'Autonomous Safety Systems' for explosion and flame containment for Class S2 Dusts.
Rota Val is a leading designer and manufacturer of Rotary Valves and Diverter Valves and associated equipment for bulk industries throughout the World. Rota Val produces a wide range of diverter valves from a compact and robust general purpose Diverter Valve for lean phase conveying, through to versatile Heavy-Duty single channel Plug Diverter Valve with constant bore section suitable for all types of conveying systems up to 5 barg, and includes ATEX certified valve options.
Also Rota Val has a patented 2 and 3 way Diverter Valve, constructed to USDA guidelines with FDA approved materials making particularly suitable for food and pharmaceutical applications. The patented diverter valve design eliminates the need for onboard controls and provides for hygienic conditions where easy cleaning is an advantage.
An extension of the basic rotary valve the blowing seal rotary valve has integral pipe connections for feeding a wide range of powdered solids direct into a pneumatic conveying line. The design offers low headroom requirements, effective purging of the rotor pockets and lower conveying velocities.
The high overall efficiency of these rotary valves makes them particularly suitable for handling low density powders which are easily fluidised. Close vane tolerances ensure high sealing and feeding efficiency with maximum durability. The prevision of alternative components and design features available enable the valve to be matched to the requirements of almost any application. Standard valves are available in Cast Iron, Stainless Steel or Aluminium, with other materials available on request.
A lightweight purpose-built Blowing Seal Rotary valve designed for chassis mounting on bulk road vehicles having an integral Blower.
The BSV valve is fitted with a hydraulic motor, which is powered by the vehicle’s hydraulic system. Designed to provide for discharging a wide range of products at around 20 tonnes/hr. Electrically powered versions are also available for static installations.
Detection systems are required to stop a rotary valve instantly if it detects rotor to housing contact, avoiding valve damage and consequent product contamination. Also, internal damage almost certainly invalidates ATEX certification for flame containment requirements. The Rota Val RotaSafe RM2 detection circuit is Intrinsically Safe and therefore suitable for all Zones.
The RM2 features innovative control electronics, effectively eliminating the incidence of false contact signals which have been a feature of other contact systems due to their inability to deal with electrical noise from unavoidable sources. The new system accurately measures contact resistance, providing a new level of detection which effectively distinguishes differences between genuine signals and product or CIP fluid conductivity
For fast and simple rotor removal, the new HR rotary valve comes with a wide range of specification options with easy manual handling functionality, achieved with sturdy linear rail configuration and conical rotor geometry.
The HR has been value engineered and includes a patented adjustment arrangement which enables precision and secure rotor adjustment. The new rotary valve enables safe manual handling in an easy, flexible and economic solution. The rotor takes advantage of Rota Val’s proven tapered design, with the rotor shaft having been tailored to suit purpose-made seals which ensure reliable extraction and insertion. Just one spanner is required for simple rotor removal.
The basic specification of the HR rotary valve is suited for most production processes. For special needs, the valve can easily be configured with several options:
- Direct or chain drive
- Drop or blow through options
- Sizes 125mm to 300mm
- ATEX option
- Polished internal option
- FDA approved materials option
- Detection sensing with RotaSafeTM for fast stop due to rotor tohousing contact
