Gate Valve

Across Dubai’s oil, gas, power, and water networks, UAE Valves is a Gate Valve Supplier in Dubai delivering positive isolation with low pressure drop for safe maintenance and steady operations. We support EPCs and plant teams with application sizing, documentation packs, and materials that match local seawater and process conditions.

How Gate Valves Work

A gate valve uses linear motion to move a wedge or slab across the flow path. When the gate lifts fully, the bore is open and pressure loss is minimal; when it lowers, the seating surfaces compress to isolate the line. Wedge designs suit general service, while parallel slide and through conduit designs provide tight isolation on steam and pipeline duty. Rising stem OS and Y gives clear position indication; non rising stem saves space in pits and underground boxes.

Gate Valve Benefits

• Full or near full bore design for very low pressure drop
• Bidirectional isolation that improves maintenance safety and leakage control
• Hardfaced seats and guides for long service life in erosive duty
• Wide choice of manual and automated operators
• Proven performance in onshore, offshore, and desalination environments

Types of Gate Valves

• Rising Stem Gate Valve (OS and Y): clear position indication and easy packing access for above ground installations
• Non Rising Stem Gate Valve: compact, protected stem for buried service and tight spaces
• Bellow Seal Gate Valve: zero stem leakage design for toxic or high temperature media
• Double Disc Gate Valve: parallel double disc for tight sealing with low operating torque
• Forged Steel Gate Valve: API 602 small bore utility and high pressure block points
• Pressure Seal Gate Valve: pressure energized bonnet seal for high temperature and high pressure power service
