Welcome to Valves Industries

Our Unit, VALVES INDUSTRIES was established in 1984 as part of our 'CTC' group manufacturing Industrial Valves since 1969.

The basic necessity to establish this new unit was to take care of our ever expanding activities. We have a team of expertise members with a lot of experience in Planning and Development, Procurement, Production, Marketing, Customer Service, etc. We have a wide product range as One Stop Quality Valve Procuring Point. We modify design of out products for specialized job or as per the need of customer.

Plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. the plugs in plug valves have one or more hollow passageways going sideways through the plug. Plug valves are simple and often economical.

When the plug is conically-tapered, the stem / handle is typically attached to the larger diameter end of the plug. Plug valve usually do not have bonnets but often have the end of the plug with the handle exposed or mostly exposed to the outside. The stem and handle often come in one piece, often a simple, approximately L shaped handle attached to the end of the plug. The other end of the plug is often exposed to the outside of the valve too, but with a mechanism which retains the plug in the body.

The simplest and most common general type of plug valve is a 2-port valve, which has two positions, open to allow flows, and shut (closed) to stop flow. Ports are openings in the valve body through which fluid can enter or leave. The plug in this kind of valve has one passageway going through it. The ports are typically at opposite ends of the body; therefore, the plug is rotated a fourth of a full turn to change from open to shut positions. This makes this kind of plug valve a quarter turn valve. There is often a mechanism limiting motion of the handle to a quarter turn, but not in glass stopcocks.

Slightly conically-tapered metal (often brass) plug valves are often used as simple shut-off valves in household natural gas lines.

It is also possible for a plug valve to have more than two ports. In a 3-way plug valve, flow from one port could be directed to either the second or third port. A 3-way plug valve could also be designed to shift flow between ports 1 and2, 2 and 3, or 1 and3, and possibly even connect all three ports together.
