Suppliers of ball valves with headquarters in the UAE offer crucial parts for controlling flow in a variety of sectors. They provide a wide variety, including multi-port and standard layouts, with kinds such as trunnion-mounted and floating valves for various pressure applications. These valves meet international standards for dependability in MEP, oil & gas, and other crucial industries. They are made of materials including PVC, brass, carbon steel, and stainless steel to withstand the harsh climate and fluid compatibility requirements. In addition to supply, they also offer actuation, customization, pressure testing, technical support, and prompt delivery throughout the Emirates.
Typical UAE Price Range (AED):
• Brass Ball Valve (1/2"–2"): 15 – 150/pc
• PVC Ball Valve (1/2"–4"): 20 – 350/pc
• Carbon Steel Ball Valve (1/2"–8"): 80 – 2,500/pc
• Stainless Steel 316 Ball Valve (1/2"–6"): 100 – 3,000/pc
• 3-Way Ball Valve (Stainless Steel, 1"–4"): 250 – 4,000/pc.
Note: Prices differ according to size, material (brass, SS 304/316, CS), end connectors (threaded, flanged, socket weld), pressure rating (150# to 2500#), and order volume.
Here are the typical technical specifications for a standard industrial flanged ball valve:
| Feature | Description |
|---|---|
| Operating Principle | A quarter-turn valve where a hollow, rotating ball (the "port") controls flow. When the port is in line with the flow, the valve is open. When turned 90 degrees, the solid side of the ball blocks the flow. |
| Standards Complied With | API 6D, ASME B16.34, ISO 17292, BS 5351, and fire-safe standards like API 607/ISO 10497. |
| Body Materials | Carbon Steel (A216 WCB), Stainless Steel (A351 CF8/CF8M for 304/316), Ductile Iron, Brass, Forged Steel (A105), and PVC/CPVC. |
| Ball & Stem Materials | Chrome Plated Steel, Stainless Steel 304/316, Brass. Stems are typically SS 304/316 for strength and corrosion resistance. |
| Seat & Seal Materials | Reinforced PTFE (RPTFE), Virgin PTFE, Nylon, Delrin, UHMW-PE, Metal Seated for high temperatures. |
| End Connections | Flanged (ANSI B16.5 Class 150/300/600), Threaded (NPT, BSPT, BSPP), Socket Weld, Butt Weld. |
| Sizes | Commonly available from 1/4" to 48" (DN 8 to DN 1200), depending on type and pressure class. |
| Pressure Rating | Standard ratings are Class 150, 300, 600, 900 (ANSI) or PN16, PN25, PN40 (DIN). |
| Maximum Working Pressure | Varies by size and class; e.g., a 2" Class 150 valve can handle ~285 PSI (19.6 Bar) at 100°F. |
| Temperature Range | Standard soft-seated valves: -20°F to 400°F (-29°C to 204°C). High-performance valves with special seats/metal seats can exceed 1000°F (538°C). |
| Installation | Can be installed in any orientation. Sufficient space must be provided for the 90-degree handle operation and for actuator mounting if required. For flammable or toxic services, specific installation standards like ANSI/API 6D must be followed. |
To minimize pressure drop, a Full Port (or Full Bore) ball valve has an internal bore diameter that is roughly equal to the inner diameter of the pipe. A Reduced Port (or Regular Port) valve is more compact and economical, but it has a modest pressure drop because its bore is one size smaller than the valve's pipe size. Reduced port is typical for general shut-off applications, while full port is utilized where flow efficiency is crucial.
For smaller sizes (usually up to 10") and lower pressure classes (Class 150/300), use a floating ball valve. A trunnion ball valve is necessary for important oil and gas applications, larger valve diameters, and higher-pressure classes (Class 600 and above). It is appropriate for actuation and harsh service because the trunnion design anchors the ball, lowering operating torque and avoiding excessive seat wear.
For a predetermined period of time during and after a fire, a fire-safe ball valve is made to retain its sealing ability and stop external leaks. In the oil, gas, and petrochemical sectors, certifications such as API 607/API 6FA guarantee that secondary metal seats and seals will continue to work in the event that fire destroys the primary soft seals (such as PTFE).
Ball valves are not advised for accurate throttling or control, even if they are technically feasible. Premature failure may result from the high-velocity flow eroding the ball surface and soft seats in a partially open position. Their main purpose is to provide on/off service. A V-port ball valve or a specialized control valve should be utilized for control applications.
