V301C Anti Surge Air Release Valve

The V301C model is an advanced triple-function air valve engineered to ensure efficient air management in pressurized pipeline systems. It facilitates the release of trapped air pockets during operation, allows rapid intake of large air volumes in the event of pipeline draining or bursts, and protects the system from pressure transients caused by high-velocity air expulsion.

Applications
* Main water transmission pipelines
* Municipal water distribution systems
* Irrigation networks
* Industrial fluid handling installations
* Hydropower and energy infrastructure

Technical Features & Key Benefits
Controlled Air Discharge: Unlike conventional air valves, the V301C self-regulates the outflow capacity to slow down the water column velocity during transient events, significantly reducing the risk of water hammer and minimizing system stress.

Reduced Spray Effect & Safer Operation: Its unique internal mechanism reduces the spray during closing, helping to prevent flooding and improve safety—particularly when compared to standard combination air valves.

Robust and Precise Design:
Single-chamber, full-bore body manufactured in ductile cast iron, rated up to PN 40 bar.
Internal guiding ribs ensure accurate and stable movement of the internal float assembly.

Corrosion-Resistant Internal Components:
The mobile block, consisting of a main float and upper disk, is integrated via a special air release system in AISI 316 stainless steel.

Includes a dedicated anti-surge obturator for additional protection.

Nozzle and gasket holder are also made entirely of AISI 316, ensuring longevity and chemical resistance.

Smart Protection Features:

The standard version includes a stainless-steel anti-insect mesh screen.

Optional outlet adaptors available for submerged installations or air redirection.

Recommended Use Cases
The V301C is particularly effective at high points or slope transitions in the pipeline profile. When installed alongside surge protection systems, it provides optimal air control and contributes to the long-term reliability of the network.
