1/2” – 3/4” – 1” Double Effect (Automatic) Air Valves

Double Effect (Automatic) Air Valves

Continuous Air Management for Safe and Efficient Pipeline Operation

Double Effect (Automatic) Air Valves are designed to automatically release accumulated air during system operation while also allowing air intake when negative pressure conditions occur. Unlike single-effect valves, these valves provide continuous air management under both pressurized and non-pressurized conditions, ensuring optimal pipeline performance at all times.

During normal operation, small air pockets that form and accumulate at high points in the pipeline are automatically discharged through the valve. This prevents air buildup, which can restrict flow, reduce efficiency, and cause irregular system behavior. In situations such as pipeline draining or sudden pressure drops, the valve allows air to enter the system, eliminating vacuum conditions and protecting the pipeline from structural damage.

Key Features

• Automatic Air Release Under Pressure
  Continuously expels trapped air during operation without interrupting system performance.
• Vacuum Protection
  Allows rapid air intake to prevent negative pressure and potential pipe collapse.
• Dual Functionality
  Combines air release and air intake capabilities in a single compact unit.
• Reliable Float Mechanism
  Operates automatically with a precise and durable internal float system.
• Long Service Life
  Designed for consistent performance in demanding environments with minimal maintenance.

Applications

• Water transmission and distribution systems
• Irrigation networks
• Pumping stations
• Industrial fluid systems

Available Sizes

This product is available in the following sizes:
