Gate Valve suppliers in UAE

Middleeast Valve is one of the largest Gate Valve Suppliers in UAE, providing high-performance valves for industries that require safe and efficient flow control. Gate valves are widely used because of their simple design, durability, and ability to provide a complete shut-off when closed while allowing unobstructed flow when open.

Working of a Gate Valve

The mechanism of a gate valve is simple and effective:

• Opening the Valve – The gate (a flat or wedge-shaped barrier) is lifted from its seat by turning the handwheel or actuator. This action creates a clear passage, enabling free flow of liquids or gases.
• Closing the Valve – The gate is lowered back into the seat, blocking the flow completely. The precise fit ensures a leak-proof seal even under high pressure.
• Intermediate Positions – Gate valves are not designed for throttling applications. Partially open gates can cause turbulence and wear, reducing valve life.

Key Features of Gate Valves

• Full Bore Design – Allows maximum flow with minimal resistance.
• Tight Shut-Off – Provides reliable sealing to prevent leaks.
• High Durability – Built from robust materials like stainless steel, bronze, and cast iron to handle extreme conditions.
• Bidirectional Flow – Enables fluid movement in both directions, adding flexibility to system layouts.

Gate Valve Operation

• Manual Operation – A handwheel or lever raises and lowers the gate. Suitable for systems where frequent adjustments are not required.
• Automated Operation – Electric, pneumatic, or hydraulic actuators automate the valve for remote or continuous use.

Gate Valve Components

• Body – The outer shell that houses all internal components, built to withstand pressure and harsh conditions.
• Gate (Wedge or Disc) – The movable barrier that opens or closes to control flow.
• Seat – Provides a sealing surface for the gate when closed.
• Stem – Connects the actuator or handwheel to the gate; available in rising or non-rising types.
• Bonnet – Covers the body and holds the stem packing, preventing leaks.
• Handwheel/Actuator – Used to operate the valve manually or automatically.
• Packing – Prevents leakage around the stem.

Functions and Applications of Gate Valves

• Shut-Off Function – Primarily used for on/off flow control.
• High-Pressure Applications – Well-suited for pipelines operating under high pressure.
• Isolation of Flow – Provides effective isolation during maintenance or inspection.
• Wide Industrial Use – Common in oil & gas, water treatment, petrochemical plants, refineries, power generation, shipbuilding, textiles, paper mills, and chemical industries.

Advantages of Gate Valves

• Very low flow resistance when fully open.
• Reliable shut-off capability.
• Long service life with durable construction.
• Suitable for both high-pressure and high-temperature operations.

Types of Gate Valves

• Rising Stem Gate Valve
• Non-Rising Stem Gate Valve
• Bellow Seal Gate Valve
• Pressure Seal Gate Valve
• Cryogenic Gate Valve
• Forged Gate Valve
