Rotary Valves & Diverters
Rotary Valves
Clyde Process provides a complete line of rotary valves suitable for applications ranging from gravity discharge of filters, cyclones and storage devices to precision feeders for dilute phase and continuous dense phase pneumatic conveying systems. Rotary valve performance relates directly to the material being handled and the application. Please contact us for assistance or advice in the selection of your rotary valve.
One of many Rotary Valves available through Clyde Process
Multi-Duty Rotary Valves are Clyde's most versatile technologies, suitable for many material handling applications. The unique TS4 seal ensures long valve life with minimal maintenance. The valve is designed for operating differential pressures less than 15 PSIG. The unique square inlet flange design allows for direct replacement of many competitive valves by matching flange patterns without exceeding overall height dimensions. The Multi-Duty Rotary Valve can be utilised to convey powder or pellets.
High-Efficiency Airlocks feature an integral doweled inspection panel for access to the interior of the housing and rotor and an angled, cast inlet to reduce shear and distribute wear.
MTA Airlocks are designed for a maximum differential operating pressure of 2 bar. They are available in gray iron, stainless steel and aluminum. The MTA rotary valve is designed to be dimensionally interchangeable from flange to flange with the popular FTA rotary airlock.
SEA Rotary Airlocks have an offset inlet and discharge to reduce product shearing of pelletized and chip materials as they pass through the inlet and discharge rotation. These valves also feature round 150 lb. drilling heavy-duty flanges.
TRA Rotary Airlocks have a tapered rotor design to allow rotor adjustment when wear occurs. The TRA features a body vent on the "up" side of the rotation to vent blow-by air from pressure pneumatic convey systems. These valves also feature round 150 lb. drilling heavy-duty flanges.
CV Rotary Airlocks feature a blow-thru end plate design which allows attachment of the convey line directly to the end plates of the airlock. Convey air flows through the CV valve, blowing material from the rotating pockets directly into the convey line. Style “A” CV valves feature an inlet baffle attachment to vent blow-by air as the empty pocket rotates up to be refilled with product. Style “B” CV valves do not include the inlet baffle arrangement.
RV Rotary Airlocks feature inboard bearings and lip seals. These valves are typically used when handling non-abrasive powders or products that will not damage the seal.
OBRV Rotary Airlocks feature outboard bearings and shaft braided packing seals. They are typically used when handling products that will damage the seals and cause bearing failure if product contact occurs.
Heavy Duty Airlocks are ideally suited for low- and medium- differential pressure systems, gravity or volumetric feeder discharge devices.
WG, FS, and FR Airlocks are fabricated airlocks with flexible, wiper blade rotors, designed to be used for applications handling stringy or fibrous products and products that have a high shear rating. These valves are intended to be used in gravity flow applications limited to a pressure of 20” W.C. and 105° C.
All airlocks feature a variety of rotor configurations and right angle or parallel shaft drive arrangements based on specific application and process needs.
Diverters
Clyde Process provides a versatile range of product and clean air diverters, which are available in 22.5 degree, 30 degree, 45 degree and 90 degree deflection angles for use in diverting air-conveyed or gravity-flow products into either of two destinations or from either of two sources to one destination.
Product Diverters:
PT 45 Diverters feature a tunnel that rotates 45 degrees port to port with no contamination. This valve includes a positive food grade rubber silicone seat at each port, and can be used in convey line applications operating at line pressures up to 80 psi. Units are available in either aluminum or 316 SS construction.
PV Diverters are available in both 30 degree and 45 degree angles with port to port rotation of 150 degrees. Equipped with a plug, these diverters are designed for powder handling applications at line pressures up to 15 psi. Plus they feature machined housings with Teflon packing gland seals, bronze shaft bushings and flanged 150 lb. drilling inlet and outlet connections. Valves are available in aluminum or stainless steel construction.
BV Diverters are available in both 30 degree and 45 degree angles with port to port rotation of 150 degrees. This valve is designed for pellet handling applications at line pressures up to 15 psi and has a machined housing with Teflon packing gland seals, bronze shaft bushings and flanged 150 lb. drilling inlet and outlet connections. Valves are available in either aluminum or stainless steel construction.
YV Diverters feature a stainless steel diverting blade that diverts at a 22.5 degree angle. The valve includes a replaceable resilient urethane sleeve to provide a tight seat for the diverting blade. Units are available in either cast iron, cast aluminum, or stainless steel and are designed for systems operations up to 15 psi.
Sealed Blade Line Diverters divert product at a 30 degree angle. This valve features a heavy-duty wear blade with a synthetic polymer insert to seal against the valve end plates.
SD Diverters discharge into scale hoppers and feature a stainless steel diverting blade and extended spout to minimize carry-over of product from the scale hopper. The valve includes a replaceable resilient urethane sleeve to provide a tight seat for the diverting blade.
Gravity Flow Diverters:
Gravity Flow Diverters feature a urethane seal sandwiched between 10 ga. plates and include flanges on all connections. Gravity flow diverters are for use in gravity-flow systems only, operating at pressures less than 20" W.C. and temperatures less than 80º F.
GA Diverters are designed to divert product flow from one source to two use points within a gravity system. The angle of each leg is 30 degrees off vertical centerline.
GY2 Diverters are designed for gravity systems with one straight through leg and a second leg to divert product flow at 30 degrees.
GY3 Diverters are three-way, gravity-flow product diverters.
Air Diverters:
AD Air Diverters are designed to direct the flow of clean air from an air source to one of two use points. Or it can be used for one of two air sources delivering to one use point.
DV Dump Valves are designed to direct the flow of clean air from a vacuum filter receiver, or loader, to a vacuum source. The dump valve allows multiple vacuum receivers configured with the valve to share one common vacuum blower.
Pneumatic Conveying Accessories:
Dump Valves & Terminal BoxesThese form the termination of the pneumatic conveying transfer pipe and secure entry of the material into the chosen reception hopper. Dump Valves are used where a number of hoppers positioned in series require selective feeding. They have two operating conditions, 'straight through' and 'dump'. In the straight through condition, a self inflating easily replaceable seal closes off the respective hopper inlet, allowing the material to be conveyed 'straight through' to the next available reception point. Terminal Boxes are used at the end of a series of dump valves or where there is only a single reception point within the pneumatic conveying system. |

 Dome Valve Switch ValvesThe Dome Valve Switch Valve is used to provide material routing, where for example, a system is delivering to more than one reception point. It allows the flow through its two outlets to be switched on or off independently, and offers the many high performance, long service benefits associated with the Dome Valve. | |
Tube ValveTube Valves are used to divert the material flow from a single source to either of two different destinations. A number of these valves placed in series within the transfer pipe can be used to direct the flow to many different destinations. In all cases, valve operation can be independent or form part of an automated PLC controlled routing system. These valves are suitable for use with a wide range of free-flowing materials typically found within minerals and other process industries. | |
Density StabilisersDensity Stabilisers are located along the conveying route at set intervals to fluidise the conveying material and facilitate the conveying process. | |
