ONE-PIECE DESIGN BONNET
Cast steel O S & Y type. The one-piece design aligns stem accurately, eliminating excessive weight and unnecessary working parts. The bonnet is equipped with stainless bushing which serves as a guide for the stem and provides back seating when the valve is wide open under pressure. All the components are precision machined.
 
SOLID WEDGE/SPLIT WEDGE
The low center stem to wedge contact in the gate valve reduces the torque considerably. Operation is easy and the wedge does not stick when the valve is closed hot and allowed to cool. The split-wedge design compensates for minor misalignments of seals due to pipe stresses and makes the valve tight on both seating faces over a wide range of pressures. Thus we have established long cycle life.

EFFICIENT WEDGE GUIDING
Long, smooth ribs are lined up with seat rings and wedge. Seating faces do not contact each other until the valve is virtually closed. T-head wedge-stem connection with an unusual low point contact reduces torque and prevents lateral stresses on the stem.

DESIGN TO BS 1868
Cast steel with uniform wall thickness smooth flowing contours and generous fillet radii to prevent stress concentrations. Designed for structural stability, mechanical strength and safe weld ability. Precision machined.
 
BODY AND COVER
Male/Female type. Bolted cover.
 
DISC
Disc design is free floating enabling rotation to avoid localised wear.

DISC ASSEMBLY
Disc to disc carrier design enables opening of the valve with low differential pressure. Disc is fastened securely to disc carrier by
means of a lock nut and cotter pin. Disc carrier is supported on a sturdy hinge pin of excellent bearing qualities. All parts are accessible from top for easy servicing.

DESIGN TO BS 5351
Cast with uniform wall thickness, smooth flowing contours and generous fillet radii to prevent stress concentrations. Designed for structural stability, mechanical strength and safe weld ability. Precision machined.

WO/THREE PIECE DESIGN CONSTRUCTION 
All ball valves are designed with either two-piece construction or three-piece construction.

MIRROR FINISH BALL
Precision machined and buffed to produce mirror like finish, minimum wear on the seat. All balls are designed to withstand the full hydrostatic body pressure.

REGULAR/REINFORCED, PTFE SEATS AND SEALS
Soft seat rings processed from PTFE oil free granular resins of virgin material completely free of reclaimed processed material is used. Reinforced PTFE seats can be provided on request.

Our constant endeavor to improve and enhance our products through research and development has lead to our recent achievement – Zero Leak Valves – a unique range of values with an incomparable advantage for the end user. This is our first step in the direction of being an environment friendly organization. We help our customers by helping them save energy.
 We have developed a valve with a specialised unique American Gland packing which is non asbestos, preloaded, self-moulding, which takes the shape of the valve stem and retains it at all times. It is compatible with most chemicals and works with the same efficiency at very high temperature (400oC) and pressure (1500 psi).

This gland packing has unlimited shell life and needs no cooling. It has a special grease which provides for easy rotation of the stem and does not decompose at high temperatures.
 
AEW GATE/GLOBE valves are guaranteed to prevent leaks of all kinds thus, saving money, material maintenance, down time and replacement expense.
