Product Description

The TARV model Triple Function Air Release Valve is a unique valve. This unique structure allows the dynamic valves to discharge air from the water system in a controlled and gradual manner, preventing slam and local up-surges. When vacuum occurs, the valves fast reaction will draw in large volumes of air into the water system, impeding down-surges and, consequently, all pressure surges in the line. The valves are normally closed when the line is not operating, thus preventing the infiltration of foreign particles and insects into the water system.

Application Rage
- Water transmission
- Pump suction line
- Water treatment and distribution systems
- Next to by-pass valve
- For irrigation

Operation Versions
- Full bore design
- Drain port (Optional) for inspection and maintenance
- Mobile block composed of two overlapping cylinders in polypropylene connected by means of a patented air release system in AISI 304
- Anti-hammer solution without having to remove the air valve from the conduct

Features
- Advanced design with simple mechanism, strong float to prevent cracking during sudden water hammer & quick closure.
- Aerokinetic mechanism to resist blow shut under higher air velocity even up to
velocity of air
- For the potential water hammer location or transmission pipeline, we should use anti shock combination air valve to prevent from damage or impact of severe water hammer.
- Anti shock device is installed on top of bonnet, It will slow down the exhausting air flow out during filling to prevent hammer impact, whenever vacuum happen, the device will drop down and let Large air into the pipeline.
- No arms or levers to prevent vibrating, bending, direct closure of the float.
- Smooth barrel outside of the float, keep float moving in specified guide rail.
- Guide barrel buffer for collision prevention, and drain easy with proper holes around the barrel during vacuum.
- Outside screen will be an option for safety and prevent insects or birds in.
- Fully fusion epoxy coated inside and outside of valve body for long term services.
- Manufacturing standard meets or exceeds BS EN 1074-4, AWWA C512
- Flange drilling and dimension meets BS EN 1092 and BS EN 558 and ANSI flange.
- Both inside & outside are coated with epoxy resin powder.
- Hydro-static test pressure for seat: PN x 1.1 , for shell: PN x 1.5 according to EN 12266-1.
