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-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.
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
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.

Gate Valve supplier Oman
Middleeast Valve is one of the greatest Gate valve supplier in Oman. Middle east valve Supplies different types of valves to different countries like Saudi arbia , Oman . Gate are used in industries to stop the flow of fluid, And gate valve has a flat closure element that slides into the flow stream. They are one of the most common types of valves, and their primary function is to allow or prevent the flow of liquids.
A gate valve is a rectangular or circular wedge that is part of a linear motion valve. To open or close a metal gate, it can be raised or lowered. Gate valves are primarily intended for on-off operations. They work best in systems where the valve is only used infrequently. They are designed for full-area flow to reduce pressure drop and allow a pipe-cleaning pig to pass through. Because the majority of the flow change happens near the shutoff, the relatively high fluid velocity causes disc and seat wear, as well as eventual leakage if the valve is used to regulate flow.
Parts Of Gate Valves
- Body
- Seat & Disc
- Stem
- Bonnet
- Wedge
Advantages of Gate Valves
- 1. They have excellent shutoff characteristics.
- They are also bidirectional.
- There is very little pressure loss through the valve.
Types of Gate Valve –
The gate is the opening and closing portion of the rising stem gate valve, and its movement direction is perpendicular to the fluid direction. The rising stem gate valve can only be opened and closed completely; it cannot be adjusted or throttled.
- Non-Rising Stem Gate Valve
The non-rising is designed so that the stem of the gate valve is fully open when the handle is rotated as far to the left as possible and fully closed and when the handle is rotated as far to the right as possible.It's also known as a Blind Stem Wedge Gate Valve or a Rotating Stem Gate Valve.
Forged Steel Gate Valves are constructed with a bolted bonnet, an outside screw and yoke, a rising spindle, and a non-rising hand wheel
Pressure seal gate valves are used for the high pressure services , which are typically for pressures above 100 bar. Since the body-bonnet joints seal better when internal valve pressure rises, the pressure seal bonnet has a special quality.
Cryogenic gate valves are used primarily in gas liquefaction systems and are designed to function successfully at temperatures below -40oC under particular service circumstances.
