A wide variety of combination air valves, kinetic air valves, and automatic air release valves for sewage, firefighting, and water pipeline systems are available from exhaust valve suppliers in the United Arab Emirates. In demanding construction projects, MEP services, and municipal water supply networks, these crucial parts are designed to automatically release air pockets, avoid vacuum development, and safeguard pipeline integrity. Commonly used materials include brass bodies with precise internal floats, stainless steel 316, and ductile iron, which provide dependable operation under high pressure.
Services include bulk distribution throughout the Emirates, project supply, technical selection assistance, and post-purchase maintenance for building management and industrial fluid control systems.
Typical UAE Price Range (AED):
• Small Brass Automatic Exhaust Valve (1/2" – 3/4"): 45 – 120/pc
• Standard Automatic Air Valve (1" – 2"): 90 – 350/pc
• Combination Air Valve (2" – 6"): 400 – 2,200/pc • Kinetic Air/Vacuum Valve (4" – 8"): 800 – 4,500/pc
• Stainless Steel 316 Body Valves: +50% to +150% premium over standard models.
Note: Valve size (inches), body material (SS 316 or brass/ductile iron), pressure rating (PN10, PN16, or PN25), and order volume all affect price.

Air pockets that naturally build at the high points in a water pipeline system are intended to be released by an exhaust valve, also known as an automatic air release valve. This ensures pipeline efficiency and system protection by preventing corrosion, water hammer, and flow constraints.
Throughout system operation, a small, accumulated air pocket is continuously vented by an automatic air release valve. To avoid a vacuum when the pipeline is draining, an air vacuum valve, also known as a kinetic valve, admits huge amounts of air and releases air during filling. Both tasks are carried out by a single body in a combined air valve.
They are essential at a pipeline's high elevations, where air naturally gathers. To preserve system pressure and avoid pipeline damage, it is also advised that valves be installed correctly after pumps, in front of control valves, and along lengthy, horizontal pipe runs.
An internal float mechanism that is worn out or malfunctioning, or a damaged seal, is usually the cause of an exhaust valve leak. Debris, rust, or an improperly sized valve for the application can all contribute to this, necessitating repair or replacement to restore the proper air release function.
The diameter of the pipeline, the flow rate, and whether air must be released during operation (small aperture) or exhausted/vacuum air must be pumped while filling/emptying (big orifice) all influence the choice of valve. For proper sizing to guarantee system efficiency, technical help from a provider is essential.
