Product Description

The TARV model Triple Function Air Release Valve is an innovative solution designed to enhance fluid dynamics within your water system. Its extraordinary architecture ensures controlled, gradual air release, effectively mitigating slam and local up-surges. During vacuum conditions, its rapid response mechanism allows substantial air intake, counteracting down-surges and minimizing pressure fluctuations. This efficient valve is normally sealed when inactive, safeguarding your water system from contaminants and pests.

Application Range
- Ideal for water transmission systems
- Perfect for pump suction lines
- Essential in water treatment and distribution systems
- Positioned next to by-pass valves
- Suitable for irrigation purposes

Operational Versions
- Ingenious full bore design
- Optional drain port available for effortless inspection and maintenance
- Innovative mobile block with dual overlapping polypropylene cylinders, linked by a patented air release system in AISI 304
- Anti-hammer mechanism in place without the need for air valve removal from the conduit

Features
- Sophisticated design with a straightforward mechanism, featuring a robust float to withstand sudden water hammer, ensuring swift closure.
- Aerokinetic technology counteracts blow shut at elevated air velocities, even
at high air velocity levels
- In high-risk water hammer areas or transmission pipelines, employ an anti-shock combination air valve to shield against potential damage or severe impact.
- The anti-shock device, mounted atop the bonnet, moderates exhaust during filling to avert hammer impacts; when a vacuum arises, it descends to admit large air volumes into the pipeline.
- Absence of arms or levers eliminates vibrations, bending, and direct float closure issues.
- Smooth float exterior ensures seamless movement within the designated guide rail.
- Guide barrel buffer acts as a collision deterrent, facilitating easy drainage with strategically placed holes during vacuum conditions.
- An optional exterior screen enhances safety, preventing the entry of insects or birds.
- The valve body is fully coated with fusion epoxy inside and out, guaranteeing long-lasting service.
- Crafted to meet or surpass BS EN 1074-4, AWWA C512 manufacturing standards
- Meets BS EN 1092, BS EN 558, and ANSI flange drilling and dimension standards.
- Epoxy resin powder coating applied both inside and outside.
- Hydro-static test pressures: seat tested at PN x 1.1, shell at PN x 1.5, compliant with EN 12266-1.
