In fluid transport systems, air entrapment is one of the most overlooked yet damaging issues. Whether it's a water treatment plant, chemical factory, or an industrial processing unit, trapped air can cause inefficiencies, reduce system life, and even lead to unexpected shutdowns. To combat this, engineers rely on a vital component — the air release valve. At Petron Thermoplast FZ LLC, we supply high-quality UPVC air release valve in all standard sizes across the UAE. Known for chemical resistance, reliability, and cost-effectiveness, our UPVC valves are engineered to meet the stringent demands of industrial and municipal flow systems.
What is a UPVC Air Release Valve?
A UPVC (Unplasticized Polyvinyl Chloride) air release valve is a specialized valve designed to automatically expel trapped air from pipelines and tanks. Air can accumulate in fluid systems during start-up, operation, or emptying and refilling processes. If left unchecked, this air can cause:
- Air locks, which block fluid flow
- Pressure build-up, resulting in burst pipes or leaks
- Inaccurate flow readings in metered systems
- Increased energy consumption by pumps
Key Features of UPVC Air Release Valves
At Petron Thermoplast, we supply precision-engineered UPVC air release valves that provide long-lasting, leak-free service even under harsh conditions. Key features include:
✅ Corrosion Resistance
UPVC is highly resistant to a wide range of chemicals, acids, alkalis, and salts—making it ideal for corrosive environments.
✅ Lightweight & Easy to Install
The valves are compact and lighter than metal alternatives, reducing installation time and support structure requirements.
✅ Reliable Operation
Automatically vents air under pressure without manual intervention. Some models include a float mechanism to detect air pockets.
✅ Durable Diaphragm or Ball Seal
Ensures precise sealing to prevent water leakage after air is expelled.
✅ Wide Pressure Range
Suitable for low to medium pressure systems (typically PN10), with options available for both vacuum and pressurized systems.
✅ All Sizes Available
From ½” to 2” (DN15 to DN50), and custom solutions upon request.
Applications of UPVC Air Release Valves in UAE Industries
? Water Treatment Plants
Used to remove air from filter beds, pipelines, and distribution systems, ensuring smooth and efficient water flow.
? Chemical Processing Units
Prevents air accumulation that can disrupt chemical dosing and fluid transfer, especially when working with aggressive chemicals.
? Irrigation Systems
Improves flow consistency in drip and sprinkler systems by eliminating trapped air, which could otherwise disrupt water delivery.
⚡ Power & Utility Pipelines
Used in condenser cooling water systems and high-flow transfer lines to prevent air locking and surge pressure.
? Municipal Water Supply Networks
Ensures uninterrupted flow in main pipelines and household connections.

How the Air Release Valve Works?
The valve contains a float mechanism or sealed chamber. When fluid flows through the pipeline, air is forced toward the high points where the air valve is installed. As air accumulates in the valve:
- The float drops (due to reduced water level), opening the valve.
- Trapped air escapes through the vent outlet.
- Once air is released, fluid re-enters the chamber.
- The float rises and seals the valve again.
Installation Guidelines
- Install at high points in the piping system, where air accumulation is likely.
- Use with vertical risers for optimal air collection.
- Avoid backpressure and vacuum conditions unless the valve is rated for both.
- Ensure proper tightening and alignment to prevent leaks.
