Available Configurations
Double Chamber - Triple Function
Double Chamber Triple Function Air Valves are designed to perform three functions: air release during pipeline filling, air admission during draining, and discharge of pressurized air pockets during operation. The aerodynamic float concept supports efficient venting without premature closure until the chamber fills with water.
Application
- Venting of air on start-up while pipelines are filled
- Intake of air on shut-off while pipelines are drained
- Discharge of pressurized air pockets during operation
Key Features
- Aerodynamic float design prevents premature closure
- Full bore and reduced bore options available
- Optional isolation valves for safety
- Manifolds available for parallel installation
- Testing cocks for inspection and control
- Threaded versions for sizes less than DN65
Key Features
Single Chamber - Double Function
Single Chamber Double Function Air Valves are designed for two functions: venting air during start-up/filling and admitting air during shut-off/draining. Not suitable for discharging pressurized air pockets while the system is operating.
Application
- Venting of air on start-up while pipelines are filled
- Intake of air on shut-off while pipelines are drained
Key Features
- Aerodynamic float prevents premature valve closure
- Full bore and reduced bore versions on request
- Isolation valves available on demand
- Manifolds for parallel installation on request
- Testing cocks for inspection and control
- Threaded versions for dimensions less than DN65
Key Features
Single Chamber - Triple Function Non-Slam
Single Chamber Triple Function Non-Slam Air Valves perform three functions (filling, draining, and pressurized air discharge during operation). The non-slam configuration is intended to reduce water hammer risk during high-velocity air discharge while maintaining high air capacity (full-bore design).
Application
- Venting of air on start-up while pipelines are filled
- Intake of air on shut-off while pipelines are drained
- Discharge of pressurized air pockets during operation
Key Features
- Non-slam design prevents water hammer
- Full bore for higher air capacity
- Optional isolation valves on request
- Manifolds for parallel installation
- Testing cocks for inspection and control
- Threaded versions for dimensions less than DN50
Key Features
Vacuum Air Valve
Vacuum Air Valves are designed primarily for rapid air intake to prevent vacuum formation during draining and column separation events. Optional configurations allow integration with additional air release functions and monitoring accessories when required.
Application
- Intake of large quantities of air on shut-off while pipelines are drained
- Column separation protection due to pipeline burst or flow fluctuation
Key Features
- Suitable for potable water and sewage applications
- Optional isolation valves on demand
- Integral air release valve installation available
- Single or double-sided lever and counterweight options
- Protection cover accessory available
- Limit switch for SCADA communications
- Manifolds for parallel installation
Key Features
Triple Function - Underground
Triple Function Underground Air Valves are designed to vent air during filling, admit air during draining, and discharge pressurized air pockets during operation in subsurface installations. The integral check/isolation mechanism is intended to simplify installation and maintenance.
Application
- Venting of air on start-up while pipelines are filled
- Intake of air on shut-off while pipelines are drained
- Discharge of pressurized air pockets during operation
Key Features
- Available in three different length options
- Integral check mechanism eliminates need for isolation valve
- Integral water drain plug included
- Surface box option available on request
Key Features
Triple Function - Sewage
Triple Function Sewage Air Valves are designed for contaminated media where clogging risk is higher. The valve integrates kinetic and automatic air evacuation functions and is designed to separate the liquid from the closure mechanism to support reliable operation.
Application
- Venting of air on start-up while pipelines are filled
- Intake of air on shut-off while pipelines are drained
- Discharge of pressurized air pockets during operation
Key Features
- Standard flushing ball valve included
- Anti-clog funnel shape body design
- Sealing body available in POM or Ductile Iron
- Non-slam option available on request
- Manifolds for parallel installation
