Vertical slide gate valves are used in air-gravity (air slide) conveying applications that require a material flow shut-off. The vertical slide gate uses a Blanchard-ground chamfered blade, allowing it to cut through fairly dense material and provide a positive shut-off. Not only can it be used to shut off material flow, it can be used as a directional flow control.
You can handle a large variety of materials with rotary throttle valves regardless of their abrasive nature or bulk density. The criteria are particle size, moisture content and temperature. Generally a product should have a particle distribution of 100% through a 20 mesh screen. Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649˚ C].
DCL can perform a product compatibility test for you to determine the optimum conveying angles and aeration volumes for your application. We’ll need a minimum product amount of 2 cubic feet [0.07 m3] to conduct a proper test.
We offer a large selection of vertical slide gate valves from 6 inches [152 mm] wide up to 36 inches [914 mm] wide and conveying capacities up to 1000 cubic feet per minute [28.3 m3/min]. They are also available in a high-top or low-top design allowing for maximum flow rate or minimum head room depending on your specific application.
A choice of construction materials allows you to effectively handle all types of products – fine, abrasive and corrosive – and difficult dusty or sanitary applications. You can also choose from the electrical options that are best suited for your environment: NEMA 4, NEMA 4X, NEMA 7, NEMA 9, 120V/220V control, 460V/415V power, etc.
Application: Shut-off and flow control of dry bulk material within a conveyor run.
Specifications: Sizes from 6” to 36” wide with capacities up to 1,000 CFM.
