A wide variety of automated control valves, globe valves, butterfly control valves, and actuated ball valves are available from Control Valve Suppliers in the United Arab Emirates. These valves are made to precisely regulate flow, pressure, and process in demanding applications. These valves are crucial for power production, water treatment facilities, HVAC systems, and oil and gas industry projects in the United Arab Emirates. Carbon steel, stainless steel 316, duplex steel, and alloy 20 are among the materials used to manage high-pressure gases and a variety of corrosive fluids. Reliability for industrial automation and process optimization is ensured by the availability of top brands like Siemens, Emerson, and GEMU.
Control valve sizing, technical selection assistance, on-site commissioning, calibration services, preventative maintenance, and emergency repair are all included in the services offered throughout the Emirates. To reduce downtime, suppliers also offer original spare parts and post-purchase assistance.
Typical UAE Price Range (AED):
• Globe Control Valves (1"–4"): 2,500 – 18,000 per unit
• Butterfly Control Valves (2"–12"): 1,500 – 12,000 per unit
• Electric Actuated Ball Valves (1/2"–2"): 800 – 6,000 per unit
• Pneumatic Actuators: 500 – 4,500 per unit
• Positioners & Accessories: 800 – 7,000 per unit.
Note: Price varies according to valve type, size, construction material (carbon steel vs. stainless steel 316), actuator type (electric vs. pneumatic), pressure rating (150# to 2500#), and order volume (single unit vs. project bulk supply).

To maintain a desired process control parameter, such as flow rate, pressure, or temperature, a control valve's principal job is to automatically modify the flow of a fluid (liquid, gas, or steam).
Similar to a regular ball valve, an on-off valve is made to operate either fully open or fully closed. A control valve can accurately and consistently maintain any position between open and closed to regulate flow because it is made for throttling applications.
The choice of control valve is crucial and is influenced by the type of fluid (steam, corrosive fluids, etc.), the needed flow capacity (Cv), the process temperature and pressure, and the required shut-off class. It is strongly advised to seek advice from a competent supplier regarding control valve sizing.
One essential piece of equipment that makes sure the valve plug moves to the precise location specified by the control signal is a valve positioner. It may adjust for stem friction and dynamic forces in the valve, decrease hysteresis, and increase control valve accuracy.
Common problems with control valves include leakage, chattering, and sticking. Upgrading the actuator or performing maintenance can typically fix sticking. Oversized valves or improper positioner tuning may be the cause of chattering. In most cases, leaks need to be checked and replaced with the valve seat or trim.
