Pressure and Gravity Diverter Valves

Conveying Diverter Valves

The Pneumatic Conveying Diverter is used to reroute product from one convey line to another.  The body is available in cast iron, cast aluminum or cast stainless steel.  An internal flap plate is fabricated of mild steel or stainless steel, with a polyurethane rubber wiper seal.  The parabolic shape provides a good seal without any gaps.  Operation is either by pneumatic air cylinder, electric linear actuator, manual lever arm or rotary type actuators. The units come standard with ASA bolt hole pattern flanges or spigots as specified by the customer, either OD tube or nominal pipe.  Sizes available are: 2, 3, 4, 5, 6 and 8 inch.

 

 

Plug Diverter Valves

Plug Diverters are heavy-duty alternatives to the flap type conveying diverter.  They have an internal plug that rotates 150 degrees to reroute product from one leg to the other.  The round hole in the plug matches the round blow through ports, making for a very smooth transition.  The units work well on applications with large particles that may get caught in a flap type diverter, causing leakage to the dead leg.  As there is no rubber seal, the plug diverter is well suited to more abrasive products.  A pneumatic rotary actuator is used to rotate the plug as standard, but can also be supplied with an electric actuator or hand crank. The units come standard with spigots as specified by the customer: flangd, OD tube or nominal pipe.  Sizes available are: 2, 3, 4, 5, 6, 8 and 10 inch.

Gravity Diverter Valves

The Gravity Diverter is also used to reroute product from one  line to another, but is used only in gravity flow applications.  The body is fabricated from mild steel or stainless steel.  An internal flap plate is also mild steel or stainless steel, with a polyurethane rubber wiper seal.  For more abrasive applications, a bucket type diverter is used where an internal chute is moved back and forth to divert product flow.  Operation is either by pneumatic air cylinder, electric linear actuator, manual lever arm or rotary type actuators. Since these units are fabricated, practically any size or divert angle can be manufactured.  Units are available as 2-way (one inlet and two outlets) or 3-way (one inlet and three outlets).  Typical divert angles are 30x30 and 0x30, but again - special angles can be made.  Flanges are round, square or even rectangular. 

Scale / Weigh Diverter Valves

Scale or Weigh Diverter Valves are a flap type diverter that reroutes product for filling hoppers or silos.  With the flaps in the down position, product bypasses the outlet.  When actuated, the flaps are lifted and product is rerouted into the hopper.  Displaced air in the hopper is carried away through the exhaust port.  These type diverters are ideal for convey lines where multiple discharge points are required in series, and are often used to fill hoppers that are being weighed - hence their name. Units are available in Cast Iron, Cast Stainless Steel and Cast Aluminum.  Typical operation is via pneumatic air cylinder or electric actuator.
