two“The most effective Bulk MaterialsHandling Valve in the World”The seal automatically deflatesduring opening and closing,thereby avoiding contact withthe dome and eliminatingunnecessary wear.The seal automaticallyinflates only when thedome is fully closed.The Spheri Valve has a world-widereputation for reliability. This results fromits simple robust design and only onemoving part. The same, simple designphilosophy also eases the task of routinepreventative maintenance and makes anyparts replacement a quick and simple task.

Always in ControlthreeThis highly innovative and well proven product from ClydeMaterials Handling is probably the most effective, fast closing, bulkmaterials handling valve in the world.It was developed by Clyde Materials Handling in 1974 for use within thecompany's own advanced range of pneumatic conveying systems.Soon afterwards the valve's much broader application capabilities wererealized and it was offered as a stand-alone product.To date, more than 10,000 Spheri Valves have been sold world-wide, forapplications across a range of industries including:- minerals, power, iron,steel, food, pharmaceuticals, chemicals, and plastics.Vane Actuated Spheri ValveUser Benefits• Full bore unobstructed material flow.• No components in material flow to wear.• Simple, fully proven design.• Can cut through moving or static columns of material.• Wide range of valve sizes: 2” (50mm) to 20” (500mm).• Forms pressure tight seal when closed.• Can cope with pressures up to 435 psi (30 bar).• Can handle material temperatures from-4°F to 900°F (-20°C to +480°C).• Long operating life.• Up to 1,000,000 cycles between major overhaulswith most materials.Spheri Valve Switch Valve• Low maintenance.• Ready availability of spare parts.Full Bore Material FlowTotally unrestricted full bore material flow is assured through the uniquedesign of the ‘dome’ assembly. A mere quarter turn is sufficient to movefrom the fully closed to the fully open position. This action positions thedome completely clear of the material flow path.Materials Handled• Abrasive • Toxic • Hazardous• Friable • Cohesive • Detergents• Minerals • Ores • Chemicals• Ash • Granules • Powders Cylinder Actuated Spheri Valve

fourSpheri Valve Succeeds Where Others Fail at LafargeAt Lafarge’s Westbury Works in the UK, a complex arrangement of divertervalves is used to route highly abrasive cement powder to any of 10storage silos. The life of the original valves was between 3 and 6 months.A 12 month trial conducted by Lafarge indicated that Clyde‘Spheri Valves’ would last for approximately 2 years - in fact, the valveswere still operating after four years - dramatically exceeding even themost optimistic of forecasts.Spheri Valves have now been installed at other Lafarge plants aroundthe world.From Fine Abrasive Powders to Cohesive MaterialsDifferent raw materials can be specified for the dome and a choice ofsurface coatings is also available. The dome is usually produced from CastIron, S G Iron or Stainless Steel, but other materials and designs will beconsidered on application.Surface coating options for thedome include:1. Chrome - For sticky and abrasive materials2. ENP or Tungsten Carbide - For abrasive materials3. Epoxy Resin - For corrosive materials4. Reinforced PTFE - For food, sticky or wet materialsThese coatings can also be extended to the internal surfaces of the valvebody and the adaptors.

Customized Solutionsfive1From Foodstuffs to High Temperature AshSeveral inflatable seals are available, depending upon the application.The choice includes a white food quality seal as well as those speciallyformulated for high temperature or other hostile applications.34Moving and Static Column Cut OffAll Spheri Valves are capable of handling fine grain materials and hardabrasive products.Vane Actuator models can cut through static columns of material up to1/8” particle size. They can also cut through moving columns ofpowders, pastes and granular products similar to coal above 1/8”.Cylinder Actuator models have the added capability of being able to cutthrough static columns of material above 1/8”.THIS CHART IS FOR GUIDANCE ONLY232 3/4 2 1/4Vane ActuatorModels1.

Other Bulk Materials Handling ValvesDump Valves and Terminal BoxesThese form the termination of the pneumatic conveying transfer pipeand secure entry of the material into the chosen reception hopper.Dump Valves are used where a number of hoppers positioned in seriesrequire selective feeding. They have two operating conditions, ‘straightthrough’ and ‘dump.’ In the straight through condition, a self-inflatingeasily replaceable seal closes off the respective hopper inlet, allowingthe material to be conveyed ‘straight through’ to the next availablereception point.Terminal Boxes are used at the end of a series of Dump Valves or wherethere is only a single reception point within the pneumatic conveying system.Their deflector plate, which deflects the conveyed material through 90°,is readily accessible for inspection or replacement.A common mounting arrangement enables Dump Valves and TerminalBoxes to be easily interchanged and both are available to suit a rangeof pipe diameters from 2”-14”.Plate & Tube ValvesPlate and Tube Valves are used to divert the material flow from a singlesource to either of two different destinations. A number of these valvesplaced in series within the transfer pipe can be used to direct the flowto many different destinations. In all cases, valve operation can beindependent or form part of an automated PLC controlled routing system.Both valve types are suitable for use with a wide range offree-flowing materials typically found within minerals and otherprocess industries.Clyde Materials Handling Inc, 1002 Ford Circle, Unit A, Milford, OH 45150, USATel: +1 (513) 576-9200 Fax: +1 (513) 576-9300 Toll-Free: +1 (888) 422-5933Email: gcooper@clydematerials.com Website: www.clydematerials.comClyde Materials Handling Ltd, Shaw Lane Industrial Estate, Doncaster, South Yorkshire, DN2 4SE, EnglandTel: +44 (0)1302 321313 Fax: +44 (0)1302 554400Email: solutions@clydematerials.co.ukClyde Materials Handling Technology (Beijing) Co.
