Product Description

The TARV model, Triple Function Air Release Valve, stands out as an exceptional valve with a distinctive design. This innovative structure ensures that the dynamic valves release air from the water system in a meticulously controlled and gradual fashion, effectively preventing sudden slams and localized surges. In the event of a vacuum, these valves swiftly react by drawing in substantial volumes of air into the water system, counteracting down-surges and subsequently mitigating all pressure surges along the line. In non-operational states, the valves remain closed, thereby safeguarding the water system from the infiltration of foreign particles and insects.

Application Range
- Water transmission
- Pump suction line
- Water treatment and distribution systems
- Adjacent to by-pass valve
- Ideal for irrigation systems

Operational Versions
- Full bore design for optimal flow
- Optional drain port for easy inspection and maintenance
- Mobile block design with overlapping cylinders made from polypropylene, connected by an innovative, patented AISI 304 air release system
- Anti-hammer solution that functions without removing the air valve from the conduit

Features
- Advanced design with a simple mechanism, featuring a robust float to avert cracking during abrupt water hammers and ensuring rapid closure.
- Aerokinetic mechanism designed to resist closure even at high air velocities
velocity of air
- For areas prone to potential water hammer or within transmission pipelines, it is recommended to use the anti-shock combination air valve to avert damage from severe water hammer impacts.
- An anti-shock device is installed atop the bonnet. It moderates the exhaust air flow during filling to prevent hammer impacts. In vacuum conditions, the device facilitates the swift intake of large volumes of air into the pipeline.
- Designed without arms or levers to prevent vibration, bending, and direct float closure.
- Smooth external barrel surface to keep the float consistently moving along the guided rail.
- Guide barrel includes a buffer for collision prevention and allows easy drainage through appropriately placed holes during vacuum conditions.
- Optional external screen available for added safety, preventing the entry of insects or birds.
- Comprehensive epoxy coating on both interior and exterior of the valve body for enhanced durability.
- Manufacturing standards meet or surpass BS EN 1074-4, AWWA C512 specifications.
- Flange drilling and dimensions conform to BS EN 1092, BS EN 558, and ANSI flange standards.
- Epoxy resin powder coating applied both inside and outside.
- Hydro-static pressure testing for seat: PN x 1.1, for shell: PN x 1.5, as per EN 12266-1 standards.
