Bulk Flow Control Equipments

Slide Gate Valves

Hyquip dust tight Slide Gates can be installed above airlock feeder to isolate valve for maintenance beneath soils or hoppers for controlled batch loading. They can be operated manually or through electric liner actuators / pneumatic cylinders. These slide gate valves are built from heavy plate sections and are fitted with hardened rack and pinion for longer life and heavy duty applications. The standard sizes suit the complete range of airlocks built by us and special sizes and designs can also be taken up to suit client specific requirements.

Rotary Airlocks

Rotary Airlock Valves are very popular in the industry and are used to minimize system air loops while transferring materials between vessels with differential pressures or as volumetric feeders for metering materials at specified flow rates. Available in Cast iron, Cast Steel, Stainless Steel, Aluminum, Heat Resistance Steel and other material of Construction from 100mm to 2000mm size to meet capacities up to 500M3/hr.

These airlocks are generally used to accomplish three basic tasks; to feed material from a bin or hopper, to deliver fines from a collector while sealing against air loss and feed material into a pneumatic conveying system against pressure. Hyquip builds a heavier airlock to closer tolerance which means better sealing properties. Our airlocks are generally chosen for applications where air leakage and gas loss are of important considerations, even though they are also frequently specified for feeder applications because of their ability to withstand the abrasion and stress of heavy duty feeder applications.

Rotary Stop Valves

The HY-FLO Rotary Stop Valves a dust-tight rapid acting valve designed for free flowing pulverized / bilk materials such as Cement, Clay, Limestone, Plastic Pellets, Coal, Grain, Fly Ash etc. The housing and head plates are of close grain cast iron construction for maximum structural stability and long life. The rotor is fabricated with a C-1045 shaft with a thick mild steel plate. Heavy duty ball bearings are used for ease of operation. Stainless steel construction throughout is optional. Units are available in 9 sizes: 100 X 100 through 760 X 760 from 250 size and above are available with an optional inspection port. Valves are available to operate with manual, pneumatic and electrical controls.

Double Cone Valves

Hyquip Cone Valves are preferred for handling highly abrasive materials like sintered dust, slag etc and for applications demanding very high differential pressures. These valves are robustly built consisting of double cone and cone seal rings which are actuated through a cam and lever arrangement. These valves function at a determined speed thus maintaining a uniform flow rate and at the same time the profile of the cone and cone seal rings are so designed to offer a perfect air seal.

The internal part of these valves like cone, cone seal rings, are made from special alloy steel for very high abrasion resistance to ensure longer life. These cone valves are extensively used in sintered plant below ESP's in steel plants. The size of cone valves are chosen from the standard range based on throughput of the material handled, size bulk density, moisture and temperature.

Diverter Valves

Hyquip Diverter valves offer an effective method for directing product flow from single source to multiple systems. The valve can be operated manually or through electric liner actuators or pneumatic cylinders. Gravity type diverter valves are used for free flowing bulk solids like Cement, Coal, Iron Ore, Aggregate etc. and arte usually provided with liners for longer life.

Designed for positive sealing and depend table switching of material flow in pressurized conveying lines. It diverts product from single source into two separated systems, while the system is in operation. Available in manual or actuator controlled versions with case Iron or Stainless Steel construction.

Flap Valves

Hyquip Flap Valves are offered in three different versions; Gravity, Motorized and Pneumatic to suit different applications in the industry. They are preferred for handling highly abrasive of lumpy materials which have tendency to stick. They can also be installed in tandem for high differential pressures. The body of valve can be cast or heavy plate construction with single or double flap machined to close tolerance for proper sealing between the flap and the body.
