Bellow seal globe valve in UAE

Middleeast valve is the biggest Bellow seal globe valve in UAE. We supply to cities like Saudi Arabia, Dubai, Cairo, and Doha.

A “below-seal globe valve” refers to a specific type of globe valve where the valve stem and disk are positioned below the sealing surface of the valve. To understand this better, let’s break down the components and workings of a globe valve:

lValve Body: The body of a globe valve is typically spherical or cylindrical in shape.

lValve Seat and Disc: Inside the valve body, there’s a valve seat and a movable disc or plug. The valve seat is where the disc makes contact to create a seal, controlling the flow of fluid.

lValve Stem: The valve stem is connected to the disc and is used to move the disc up and down, controlling the flow of the fluid through the valve.

Now, in a “below-seal” design:

lValve Seat Position: The valve seat, where the disc makes contact to form a seal, is located below the normal flow path of the fluid.

lDisc Movement: When the valve stem is turned or moved, the disc moves in a downward motion towards the valve seat to close the valve and forms a seal by making contact with the seat.

lSealing: When the disc seals against the valve seat, it prevents the flow of fluid through the valve. Conversely, lifting the disc away from the valve seat allows fluid to flow through the valve.

The design of the Below Seal Globe Valve in the UAE ensures efficient sealing and control of fluid flow. In the closed position, the disc securely rests against the valve seat, effectively blocking the passage of fluid. Upon opening the valve, the disc is raised from the valve seat, enabling the smooth flow of fluid through the valve.

Description:

Advantages:

• It has a double seal that consists of packing and bellows.

• It decreases medium fluid loss and advances environmental and safety protection.

• It has the ability to save energy because it works to cut down on leakage-related energy losses.

• The valves last a long time.

• There is a significant reduction in the cost of operation and maintenance.

Applications:

lHigh integrity pressure protection system

lHandling solids (powders, fines, dust, and catalysts)
