CLYDE DOME VALVES


DO YOU HAVE PROBLEM VALVES COSTING YOU DOWN TIME AND MONEY?

The Dome Valve - The operating efficiency of all Clyde Materials Handling Systems relies upon the original and world's best Dome Valve, currently installated in over 10,000 applications worldwide.  Simple in design and low in maintenance, this high performance valve is used thoughout a wide range of industries.  In action the Clyde Dome Valve is a pressure tight compressed air operated valve, capable of returning over one million maintenance-free cycles, even in abrasive, hazardous or toxic applications.  ATEX compliant - the fast-closing cut-off valve incorporates a unique inflatable sealing mechanism, this provides the pressure tight seal, against the dome surface when in the closed position.

..Benefits of the Dome Valve

Full Bore Material Flow
Totally unrestricted full bore material flow is assured through the unique design of the 'dome' assembly.
A mere quarter turn is sufficient  to move from the fully closed to the fully open position.  This action
positions the dome completely clear of the material flow path.

From Fine Abrasive Powders to Cohesive Materials
User options extend to the choice of 'Dome', both in terms of raw material and any surface coatings required.  The Dome is usually produced from Cast Iron, S G Iron or Stainless Steel, but other materials and designs will be considered on application.

From Foodstuffs to High Temperature Ash
Several inflatable seals are available, depending upon the application.  The choice includes a white food quality seal as well as those specially formulated for high temperature or other hostile applications

Moving and Static Column Cut Off
All Dome Valves are capable of handling fine grain materials and hard abrasive products.  Vane Actuator Models can cut through static columns of material up to 2mm particle size.  They can also cut through moving columns of powders, pastes and granular products similar to coal above 2mm.  Cylinder Actuator models have the added capability of being able to cut through static columns of material above 2mm.
