The company
Hyquip since its inception in the year 1984, has been focusing on providing innovative engineering solutions to the Indian industry. Over the years, Hyquip has developed many import substitutes like Aluminum extrusion handling systems, High speed battery packaging
HYQUIP has addressed most of the critical applications in the Cement, Steel, Sugar and Power sectors, a dependable experience
systems, Self cleaning rotary airlock valves, Double cone valves, Screw coolers for 6500C temperature materials cooling and in the process received many national and international awards.
The company has now evolved into a dependable supplier for Flow control products, Bulk material handling systems, Dust control systems, MSW processing machinery for compost, RDF, Plastics and Waste to energy plants in technical collaboration with Hitachi Zosen Inova.
The products are manufactured under well established manufacturing process and quality assurance plans in most modern Factories, geared up to deliver on time at competitive prices.
In the journey to becoming a world class Cement, Steel, Power and Paper plant, Hyquip's products are chosen to overcome the most challenging applications and under the most extreme conditions to enhance the efficiency of their plants.
ROTARY AIRLOCKS Rotary airlock valves are very popular in the Industry and are used to minimise system air loss 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,
Bag gas e Fe ede r
Aluminum, Heat resistant Steel and other materials of construction from 100mm to 2000mm size to meet capacities upto 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 tolerances 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
Raw Mill Feeder
frequently specified for feeder applications because of their ability to withstand the abrasion and stress of heavy duty feeder applications. You can depend on Hyquip airlocks performing as specified, as our specifications are intentionally conservative to help ensure this. Coal

The Rotary Airlock Features Eight blade cast rotor for maximum seal
75 - 125 Âľ clearances for minimum air leakage
Available in round or square models Round-bottom pockets discharge more efficiently Heavy cast housings and end plates provide rigidity Casting construction All models drilled for air purge of seals 10mm Vane thickness
Bosses drilled and tapped for pocket venting
Heavy duty outboard permanently sealed bearings Keyed through-shaft
Fully gussetted base
Long Wear Packings and Bearings
Bearing retainer and packing gland are part of the end plate casting. Seals can be replaced without removing bearings and end plates. Externally accessible and adjustable.
Bearings are double sealed and lubricated for life. Bearings on drop through airlocks are mounted far outboard of seals to permit access to seals and prolong bearing life.
Multiple rows of seals, Super seal / Teflon available at no extra cost.
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,
Motorised Double Cone Valve
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 the Cone Valves are choosen from the standard range based on throughput of the material handled, size bulk density, moisture and temperature.
Sectional View Cone and Seal Ring
FLAP VALVES Hyquip Flap Valves are offered in three different versions; Gravity, Motorised and Pneumatic to suit different applications in the industry. They are preferred for handling highly abrasive or lumpy materials which have tendency to stick. They can also be installed in tandem for very high differential pressures.
Motorised Flap Valve
The body of the valve can be of cast or heavy plate construction with single or double flap machined to close tolerance for proper sealing between the flap and the body.
Gravity Flap Valve
No rotary action means no need to build clearance (leakage) into the valve. Double flaps ensure that the seal is never lost throughout filling and emptying of the valve. Full-throat opening eliminates bridging, jamming and material build up. Seat and flapper can be reground several times to bring them back to original condition and performance. Housing does not come in contact with material allowing it to last much longer life.
Pneumatic Flap Valve
ROTARY STOP VALVES The HY-FLO Rotary Stop Valve is a dust-tight rapid acting valve designed for free flowing pulverized / bulk 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.
Typical Applications of Rotary Stop Valve
Below Cooler ESP for Discharge of Hot Clinker Dust
Bin to Belt Conveyor
Silo Unloading into Trucks
Feeding to Packer Machine
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 linear actuators or pneumatic cylinders. Gravity type diverter valves are used for free flowing bulk
Special designs are available for three / four way diverting of
solids like Cement, Coal, Iron Ore, Aggregate etc. and are
materials, however detailed study is required of the layouts
usually provided with liners for longer life.
and the deliveries shall be much longer than the standard sizes and design.
Motorised Diverter Valve
Designed for positive sealing and dependable switching of material flow in pressurised conveying lines. It diverts product from single source into two separate systems, while the system is in operation. Available in manual or actuator controlled versions with case Iron or Stainless Steel construction.

PC Line Diverter Valve
SLIDE GATE VALVES Hyquip dust tight Slide Gates can be installed above airlock feeder to isolate valve for maintenance beneath silos or hoppers for controlled batch loading. They can be operated manually or through electric linear actuators / pneumatic cylinders.
Motorised Slide Gate Valve
Pneumatic Slide Gate Valve
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.
