Wafer butterfly valve supplier in Dubai
Middleeast Valve is well known Wafer butterfly valve supplier in Dubai .Which supplies good quality
of valves to Khor Fakkan, Kalba. A wafer butterfly valve is a type of butterfly valve that is designed to
be installed between two flanges in a piping system. It consists of a circular disc that is mounted on a
shaft, which is connected to a handwheel or actuator. When the disc is rotated, it opens or closes
the valve by moving the disc either parallel or perpendicular to the flow of fluid through the valve.
Wafer butterfly valves are often used in low-pressure and low-temperature applications, and are
commonly found in water treatment plants, food processing facilities, and chemical plants. They are
known for their compact size, light weight, and ease of installation, and are often preferred over
other types of valves due to their low cost and simple design.

WAFER BUTTERFLY VALVE ADVANTAGES
There are several advantages to using wafer butterfly valves:
1. Compact size: Wafer butterfly valves are relatively small and lightweight, making them easy
to install in tight spaces and reducing the overall size and weight of a piping system.
2. Low cost: Wafer butterfly valves are generally less expensive than other types of valves,
making them a cost-effective choice for many applications.
3. Ease of installation: Wafer butterfly valves are relatively easy to install, as they can be
installed between two flanges without the need for additional support or brackets.
4. Simple design: Wafer butterfly valves have a simple design with few moving parts, which
makes them easy to maintain and reduces the risk of failure.
5. Quick opening and closing: Wafer butterfly valves are able to open and close quickly, making
them suitable for use in applications where rapid flow control is required.
6. Good flow control: Wafer butterfly valves are able to provide good flow control, as the disc
can be precisely positioned to vary the flow of fluid through the valve.
7. Low pressure drop: Wafer butterfly valves have a low pressure drop, meaning that they do
not significantly reduce the pressure of the fluid flowing through the valve. This makes them
suitable for use in high-pressure systems.
8. Resistance to corrosion: Wafer butterfly valves are typically made of corrosion-resistant
materials, making them suitable for use in harsh environments.
INDUSTIRES IT IS USED IN
Wafer butterfly valves are commonly used in a wide range of industries, including:
1. Water treatment
2. Chemical
3. Oil and gas
4. Petrochemical
5. Power generation
6. Plumbing

BUTTERFLY VALVE
Middleeast Valve is one of famous Butterfly valve supplier in Oman.Which Supplies different types
of valves to different cites like Hatta , AI Dhaid. Butterfly valves are a family of quarter-turn
rotational motion valves that are used in pipelines to shut-off flow. It is often stated that butterfly
valves can be utilised to control flow. We do not advise doing this, though, as it may harm the valve
disc and impair the sealing capabilities.
Advantages of Butterfly valve:-
• Easy to install and operate
• Energy efficiency has improved.
• Good for on/off and throttling
• Good for slurries part
• Large seating area
• Larger sizes are available.
• Less assistance is required.
• Lightweight
• Low operation torque allows for simple operation.
• Low-pressure drop.
Types of Butterfly Valve
• Lug Butterfly Valve
Lug-style butterfly valves are usually composed of metal such as ductile iron or steel For bolt
connections, they have threaded tapped lugs placed on the valve flanges. Although a blind flange is
generally advised, lug-style butterfly valves are adequate for end-of-line service.
• Wafer Butterfly Valve
A wafer butterfly valve is one form of valve used to regulate the flow of fluids in a pipe
system. This valve is made up of a disk-shaped component that is fastened to a stem. The valve can
open and shut because of the disk's ability to rotate
• Flanged Butterfly Valve
A quarter-turn valve is a flanged butterfly valve. To start or halt fluid flow, the valve disc must be
spun a quarter turn. A quarter turn of the hand lever or hand wheel in the anticlockwise direction
opens a butterfly valve of the flange type (90 degrees)
• Double eccentric Butterfly Valve
Double eccentric butterfly valves are most frequently utilised in below-ground water supplies
systems. When putting butterfly valves below, a shallower bury depth is necessary, and they are
often more affordable than gate valves, particularly when they are substantial in size.
• Triple eccentric Butterfly Valve
Triple eccentric butterfly valves are used for prevent galling and scratches between the metal seat
and the metal disc .Only after the seal is fully closed, as a result of its special design, does it come
into touch with the seat.
• Double offset Butterfly Valve
Double offset butterfly valves are frequently referred to as high-performance butterfly valves and
have the following two offsets from the body's centre: The disc seat and the centerline of the body
seal are separated by the shaft axis. The centre line of the valve or pipeline and the
• Triple offset Butterfly Valve
The triple offset technique, as the name suggests, employs three different offsets to produce a
bubble-tight shut-off. One of the offsets relates to where the valve shaft is situated in relation to the
bore's centerline. The distance between the shaft and the centerline of the disc/seat sealing surface
is another offset.
Industries that use Butterfly Valves:
• Chemical
• Compressed air services
• Drilling and production
• Dry bulk handling
• Fire protection
• Fuel handling systems
• Lubrication system
• Marine systems
• Oil and gas and many more…
