XGD Valve Launched at  Solids Exhibition 

Rota Val, Chippenham based manufacturer of rotary, diverter and slide valves, is launching three new products, including a totally new valve range, at the Easyfairs Solids 2006 Exhibition.

The new XGD rotary valve is aimed specifically at medium duty applications, offering significant cost savings compared to heavy duty valves but retaining many of their features and options, such as outboard bearings, robust construction, air purged glands and high temperature specifications.

XGD rotary valves are suitable for feeding lean phase conveying systems and, in common with Rota Val’s other valves, ATEX certified versions can be supplied.

Standard valve specifications will be available ex stock and whilst the XGD valves are offered at highly competitive prices, customers still benefit from the support and unrivalled applications experience for which Rota Val is well known.

Other features include composite round / square flanges and the option of chain or direct drive.

Steve Winton, Rota Val’s sales manager commented: “Rota Val has a depth of technical and applications knowledge and experience that is second to none. The Company is rightly renowned for technical excellence and an ability to develop valves specifically to suit a customer’s application.”

“By launching the XGD valve range, we can complement this with the volume production of relatively standard valves. These offer significant cost savings and excellent delivery times to customers who do not need heavy duty or special build valves.

“Of course, those same customers can also buy with the reassurance that the technical excellence is readily available should they need it, as we also continue to maintain focus on our special build business. We really can offer the best of both worlds.”

New Fast-Clean Blowing Seals 

Rota Val ‘Fast-Clean’ Blowing Seals (BSFCT) are designed to bring new standards of safety, ease of use and reliability to applications with high cleanliness needs.

The range offers users increased productivity through minimal down-time and greater reliability as a result of simple, safe disassembly procedures.

The fully ATEX explosion proof design ensures safe use with hazardous materials.

Bottom-mounted sliding rails permit accurate alignment of the rotor to housing when being removed or replaced.

They also allow a rotor support saddle to be used which eliminates the need for manual lifting or special equipment under primary cleaning operations, enabling users to meet safe handling legislation.

Rota Val ‘Fast-Clean’ Blowing Seals are particularly suited to any application requiring frequent cleaning of internal components, whether for cleanliness or hygienic purposes.

The new BSFCT valves will be of particular interest to the Dairy, Food and Pharmaceutical industries.

True “Blow Through” design eliminates an entrainment trough for maximum rotor pocket purging and provides superior handling of sticky or fragile products.

Features

Fully ATEX 94/9/EC certifiable as Equipment or Autonomous Protective System for Explosion Protection.

Every explosion containment valve is pressure tested and certified prior to release, this is unique to Rota Val.

“Investment cast” for superior finish and quality.

Smooth external profile for ease of cleaning and wash-down.

Economical to polish due to smooth profile, giving highly competitive prices.

Minimal internal cast surfaces for maximum hygiene and ease of polishing.

Bolt-on pipe connections can be supplied to match conveying line size.

Available with the RotaSafe RM valve protection system for protection against valve damage and product contamination.

Valve Protection System Announced

Rota Val’s new Valve Protection System is designed to detect any contact between the rotor and valve housing, instantly isolating power to the drive motor.

The RotaSafe RM Rotor Monitor will be primarily of interest to customers where product contamination is a significant issue.

Contact between the rotor and valve housing can result from excessive load on the rotor causing deflection, or product build-up (glazing) on contact surfaces..

Ingress of ‘tramp’ material in the working clearances, bearing failure, excessive temperature, incorrect assembly and lack of maintenance can also cause rotor contact with the housing.

RotaSafe RM offers significant benefits to users.  The system prevents valve material shedding into and therefore contaminating the product being handled and protects valve components from serious damage.

It also prevents valve start-up if assembled incorrectly.  Prevention of damage to the internals of ATEX Autonomous Protection valves is vitally important to avoid invalidation of ATEX certification through an increase in rotor clearances.

The detection circuit is Intrinsically Safe and ATEX Certified for all Zones. (The Control Module must be mounted in a Safe Area). 

The Control panel is programmed to eliminate ‘nuisance tripping’ from circuit detection due to partial conductivity through wash-down fluids or through the product being handled.

The RotaSafe RM is also suitable for retrofitting to existing rotary valves.

     HBST250 Blowing Seal 50mm conveying line

Rota Val announces an extension to their range of unique 'Hypergienic' Rotary valves in the form of new Blowing Seal version. The concept is primarily aimed at the Food and Pharmaceutical industries where a high degree of hygiene and ease of cleaning is paramount.

200mm 'Pipe Selector' Diverter Valve

Even with 10 different sizes (20 mm to 150 mm) within their existing highly successful Pipe Selector Diverter valve range; this was insufficient to meet the needs of a leading French Pharmaceutical company.

The valve illustrated although similar in design and incorporating the same basic features as the standard range of Diverter Valves was specially designed to incorporate a number of additional special features.

The extremely corrosive Pharmaceutical product being conveyed was suspended in a toxic gas and therefore it was essential that the possibility of escape to atmosphere was totally eliminated. A special reinforced gas tight housing with manifolds for Nitrogen purge was the solution. Further due to the nature of the product it was necessary to manufacture from a special stainless steel (254 SMO).

Other features: two sight glasses for inspecting the inside components and pharmaceutical standard pipe connections.

Full Quality Assurance validation procedures and documentation to include ATEX Zone 1 & Zone 21 (II 2GD 85°C) were provided.
