Peep Hole Ball Valve for Blast Furnace
This valve is used on Blast Furnace to view the flame quality. Usually a Sight Glass is provided
for this purpose which is always exposed to the high temperature of the furnace, leading to
frequent breakages. To avoid this, a Ball is provided which protects this Sight Glass as the
Valve is opened only when the flame quality is to be checked. As the Sight Glass is not
subjected to high temperature for long durations, it last longer.
MOC : WCB
SIZE : 0.5" to 1"
ENDS : SCREWED
DESIGN : 3 PIECE

Flange End Ball Valve with Limit Switch
It is required some times to know the position of the valves by an electrical signal. One or Two
Limit Switches are provided depending on the requirement to know if the valve is open or
closed. The Valves come with complete bracket for mounting of the limit switches. Also a
physical color indicator is provided to know the position.
MOC : WCB/CF8/CF8M
SIZE : 0.5" to 4"
ENDS : FLANGED / SCREWED / SOCKET WELD
DESIGN : 3 PIECE
NUMBER OF LIMIT SWITCHES : 1 OR 2

| Cavity filler Ball Valve - Many industries encounter problem of residues in the ball valve. These residues contaminate the media and hinder the operation of the ball valve. In cases where the fluid is meant for human consumption, it becomes all the more dangerous as it may contaminate and make the fluid toxic. In cases where the media changes from time to time, such as color of paints, the residual paint contaminates and changes the color. Also, some users dismantle the valves to clean them, leading to damage of internals and subsequent leakage. It is therefore necessary to eliminate the deposition of this residue material. The reason why this residue deposits itself in the ball valve is because of the design of the valve. During the half open position of the ball valve, a gap is created between the ball bore and the body. The fluid can easily creep into this gap and get itself deposited in this cavity of the body. To avoid the fluid getting into this cavity, the cavity has to be plugged. This can be done by extending the seats in such a manner that it is always in contact with the ball, thus avoiding the gap. This type of ball valve is known as Cavity Filler Ball Valve. As per the requirement of one of our clients this ball valve has been successfully developed and tested.

Electropolished Ball Valves
Stainless Steel Investment Castings are sand blasted to remove grinding / filing marks
and other irregularities. This leads to blackening of the castings. Usually these
castings are assembled as it is, making the ball valve look darkened. Some customers
complain that the valves do not APPEAR like stainless steel. To solve this problem the
valves are electropolished to give them a bright look.

Non Welded Fabricated Ball Valves
Usually to fabricate ball valves, where standard castings are not available, welding is
preferred. Welding poses some major challenges, such as formation of heat affected
zones which may have different material properties and color. Improper welding can
also lead to leakage and rework. Moreover, the reworked valve's appearance is
unacceptable. To overcome this hurdle, a new technology to join the flanges was
developed. Here the flanges and valve bodies are screwed together and machined to
eliminate gaps. These bonds are leak-proof and the appearance of the valves is
excellent.
