FOR IMMEDIATE RELEASE
DONALDSONÒ TORITÒ OFFERS A FULL LINE OF ROTARY VALVES FOR DUST COLLECTION AND DISPOSAL
MINNEAPOLIS, July 25 — Donaldson Torit offers a full line of rotary valves for use as airlocks in dust collection systems. These valves automatically and continuously transfer dust from the dust collector hopper to a conveying system or collection container. The valves can also be used in conjunction with pneumatic conveying systems or as metering devices.
The benefits of Donaldson Torit rotary valves are twofold: the valves reduce downtime and labor by automating dust removal, and they maintain vacuum pressure inside the collector for optimum performance.
Donaldson Torit rotary valves are available in 3 styles, each in a variety of sizes to fit all popular makes and models of dust handling systems.
- Model “AN” valve offers a cost-effective solution for handling most nuisance dust discharge requirements. The AN valve has a double wiper rotor for a precise seal in low air pressure applications, such as wood dust, cement, cosmetics, chemical, etc. This valve can be configured with square or round inlet/outlet openings, in various sizes to accommodate specific customer requirements.
- Model “CI” valve is a high volume, high pressure valve, ideal for many process dust handling applications. It is also well suited for high pressure pneumatic conveying systems. Its unique design allows it to handle 3 to 4 times more material than competitive rotary airlocks with the same inlet opening. The bearings are outboard to protect them from dust contamination and for easy service access. CI valves can also be supplied with a variety of optional blade tips (plain, brass, stellite, wiper, adjustable) and beveled or cutter blades, for specific applications.
-
- Model “F” series valves are heavy-duty cast iron feeder valves designed exclusively for use with high pressure pneumatic conveying systems in dry bulk material applications, including difficult sticky products like sugar. F valves are fitted with outboard bearings to protect them from dust contamination and make maintenance easy. This valve is often used to meter materials from a large storage bin into a pneumatic conveying line for transfer to another area of the facility.
Rotary valves are an option on all Donaldson Torit dust collection equipment (baghouses and cartridge-style dust collectors), and are also available as add-on or replacement units via the Donaldson Torit aftermarket group.
Donaldson Torit designs, manufactures and markets in-plant air filtration and pollution control systems and replacement products that help eliminate dangerous dust, fume and mist contaminants from your workplace. Donaldson Torit is a part of the Donaldson Company, a leading worldwide manufacturer of filtration systems.
