Wafer And Lug Type Butterfly Valves

A butterfly valve is generally used in chemical or food industries to regulate or isolate the flow of liquid, gas and solid. The valve manufacturers are in high demand and new companies of valve manufacturers are rising in the market rapidly. Industrial Valve dealers in India offer high-quality valve as the demand is growing.


  • POPULAR BUTTERFLY VALVES– When it comes to the butterfly valve, there are four types including Wafer type end, lug type ends, butt welded type ends and both flanged ends. They have a wide demand in several industries like sugar, oil, chemical industries etc. Butterfly valves, mainly the wafer valves and lug type valves are always tested to meet industrial requirements.
  • DIFFERENCE BETWEEN WAFER AND LUG TYPE VALVES– The wafer body type valve is easy to install but cannot be used as isolation valve. They don’t have attachment lugs. Lug type valves, on the other hand, have lugs attached to the flanges on the end and can be removed easily.
  • DEMAND OF BUTTERFLY VALVESSupplier of butterfly valves is in high demand because these valves can be used even in high-pressure services. Butterfly valves need less time to open and close, thus maintenance costs compared to other valves like ball valves.
  • ADVANTAGES OF BUTTERFLY VALVES– Due to its lightweight design and compact nature butterfly valves is suitable as compared to other valves. They are most popular and high in demand among the Valves Suppliers in Delhi.  They can be widely used in cooling water, fire fighting, vacuum services with good performance.
  • OTHER TYPE OF BUTTERFLY VALVES EXCEPT FOR THE WAFER AND THE LUG– While the wafer type cannot be used as a pipe end, lug type can be used as a pipe end. The other two form of butterfly valves mainly the welded one is used for high-pressure applications.

With the demand of valves growing in the Indian market other valves like balancing valves, a globe valve, ball valve has also increased. Although, butterfly valves still remain the most popular particularly because of its low cost and easy installation.

Types of Pipe valve

Valve is a device that can control the flow and pressure of the fluid in a pipe. A few either starts or altogether stops the flow of fluid whereas there are some that partially obscures the path.

The different types of pipe valve are explained below in detail.

1. Ball Valves

Ball valves operate with a quarter-rotary motion. In a ball valve, the flow path is manipulated by the ball-shaped disk which requires a 90-degree turn of the valve handle. It is comparatively smaller in size and lighter than a gate valve.

2. Butterfly Valves

Butterfly valve can start, stop, and regulate the flow path but only to some extent. It is a simple valve that can be operated by a 90-degree turn of the valve handle. A butterfly valve is not normally designed to give a positive shut-off but modern technology has provided room for improvement in its blueprint. This valve is now capable of a bubble-tight shut-off.

3. Check Valves

Check valves, or NRVs (non-return valves), supports the unidirectional flow of fluid only. Their function is to check backflow. In check valves, backflow is prevented by “stoppers”. The different kinds of “stoppers” are ball, piston, and swing. Ball and piston check valves work by demanding a little amount of inbound flow pressure. The movement of fluid in a swing check valve is through a pivoting flap which opens only in one direction and ensures that there is no backflow.  

4. Gate Valve

Gate valves are the most ordinary and the most frequently sold valve type in the industrial valve trade. These act as a block valve for isolating pipe systems since their properties are limited to either opening or closing. There is no restriction in the flow path once a gate valve is opened as it opens all the way. Gate valves are preferred in a straight-line system that requires minimum obstruction. You can regulate a gate valve with the help of a hand-wheel or a piston actuator.

5. Pressure Reducing Valve

If you are looking for a device to reduce the water pressure, pressure reducing valve is your answer. These valves get down to work by bringing down the quantity of water that flows through a pipe. With the valve, water that was pushing through the pipes at high pressure will be efficiently slowed down.
