Diverter Valves, Slide Gates, and Rotary Airlocks
Flo-Dynamics supplies a wide variety of slide gate valves, airlocks, and diverter valves. Applications include all types of dry solid processes and associated industries.
Slide Gate Valves
Slide gates are designed to stop, start, or meter the flow of dry solids. We can supply valves for any conveying application such as food, pharma, aggregates, minerals, chemical, and plastics.
Slide Gates
Ideal for controlling dry bulk material in gravity flow, dilute phase or dense phase pneumatic conveying applications. Vortex slide gates are designed and engineered with two main principals in mind: 1. Extend the service life of the valve and 2. Perform maintenance without taking the valve out of line. Conventional knife gates and butterfly valves were commonly used in dry bulk solid material handling systems. Though knife gates and butterfly valves are well-designed for handling liquids and gases, they are ill-equipped for handling dry bulk solids.
Iris Valves
The patented Vortex® Iris Valve is designed specifically to handle dry bulk solids in gravity discharge of free-flowing material from bins, bulk bags, chutes, and hoppers. The Vortex Iris Valve is designed with stainless steel control rings, metal handle and trigger lock, and nylon shim for durability and smooth actuation. A form fitted fabric sleeve provides a dust tight seal and product barrier, which prevents material leakage into the atmosphere.
Titan Heavy Duty Gates
The Vortex Titan Series Maintenance Gate is designed for use in gravity flow applications handling heavy duty and/or abrasive dry materials. Its purpose is to shut off material from a hopper or silo when maintenance of downstream equipment is required, or if an upset condition occurs. In the open position, the gate can seal slight aeration.
Diverter Valves
Diverter valves will divert bulk materials from a single stream to multiple streams, or converge materials from multiple streams to a single stream in gravity flow, dilute phase or dense phase pneumatic conveying applications. Flo-Dynamics can supply standard or custom engineered valves a wide range of applications serving many industries including chemical, cement, coal, food, frac sand, grain, minerals, petrochemical, pharmaceutical, plastics, polymer, rubber and mining.
Gravity Diverters
Gravity flow applications where dry bulk solid materials must be diverted from one source toward up to three destinations. Suitable for non-abrasive to abrasive powders, pellets and granules. Modifications available for handling corrosive materials and/or for wash-down environments.
Pneumatic Diverters
Diverting or converging materials in high cycle applications. Common in storage fill and/or storage transfer applications. When applied in minimally abrasive applications or as an air directional valve, Wye Line Diverters often record more than 10 million cycles over the course of their service life.
Titan Heavy Duty Diverters
Used to divert heavy-duty and/or abrasive dry bulk solid materials from one source toward two or three destinations in gravity-fed applications. The Vortex® Titan Lined Diverter™ offers in-line maintenance features, durable materials of construction, reduced downtime, prolonged service life and many other significant advantages over alternative flap diverters.
Loading Spouts
Loading Spouts can be supplied for stationary or variable position filling applications. They provide fast and steady material flow during the loading of dry/bulk solid materials in open and/or enclosed vessels such as trucks, railcars, tank vehicles, ships, barges, and stockpiling. These loading spouts are designed to capture fugitive dust, prevent material waste, and ensure plant and environmental safety, with low maintenance and service expenses.
Loading Spouts
Vortex® Loading Solutions provide fast and steady material flow during the loading of dry/bulk solid materials in open and/or enclosed vessels such as trucks, railcars, tank vehicles, ships, barges, and stockpiling. These loading spouts are designed to capture fugitive dust, prevent material waste, and ensure plant and environmental safety, with low maintenance and service expenses. From the retractable loading spout attached to the bottom of a silo/hopper or located at the end of an air conveying system, to the dust collecting filter system, to the loading spout positioner, Vortex Loading Solutions offer a complete line of versatile loading spout systems for your loading process.
Spout Positioners
Vortex® Spout Positioners are designed so that materials pass through a fixed inlet. Above, a traversing hopper slides across a fixed support pan. A loading spout is attached beneath the traversing hopper to allow exact positioning of the spout above a truck or railcar waiting below. Loading spout positioners are made out of steel and can be designed and manufactured to meet your individual project specifications to handle almost any flow rate and travel distance.
Spout Filtration
Vortex dustless spout filtration systems are engineered to capture the fugitive dust emitted from the spouts and deposit it back into the material flow during the loading process, eliminating material loss. These filter systems are more cost-effective than a free-standing dust collection system, which often requires the installation of additional ductwork, discharge airlock and some way to reintroduce the material back into the system. These very compact filter systems are used in conjunction with standard volume loading spouts in enclosed, open, or combination loading applications. They feature a unique square-shaped design, which allows for a more low profile and compact model.
Rotary Airlocks
Rotary airlocks and feeders are designed for metering materials in gravity or applications with pressure differentials. They are available in standard duty, heavy duty, highly abrasive, quick clean, and sanitary applications.
Heavy Duty Airlock
The HDX Heavy-Duty Drop-Thru Rotary Airlock Valve is built for high-pressure, high-temperature applications, withstanding pressure differentials up to 22 psi. Featuring extra-thick construction, heavy-gauge rotor vanes, oversized outboard bearings, and the Meyer PRO-TEC Inflated Shaft Seal, the HDX valve delivers exceptional durability, reliability, and reduced maintenance in the toughest dust collection environments.
Double Dump Valves
The MPFTA A-Series Cast Double Flapgate Airlock Valve is engineered for medium-pressure applications and standard operating temperatures up to 650°F. Built with a cast iron housing and White Iron/Ni-Hard seats and flaps, the MPFTA offers a durable, cost-effective alternative to rotary valves. Ideal for use with dust collectors, precipitators, and cyclones, the MPFTA handles pressure differentials up to 193″ WC (7 psi). It’s also a strong replacement for rotary airlocks prone to premature wear. To extend service life, the seats and gates can be re-ground.
Quick Clean and Sanitary
The Meyer Industrial KLEAN-IN-PLACE II® rotary airlock valve is engineered for fast, efficient cleaning with minimal downtime. Its balanced 2-RAIL design allows in-place rotor cleaning or full removal, while meeting FDA, USDA, 3A Dairy, and NFPA standards—making it ideal for food, dairy, pharmaceutical, and chemical applications.
