Hidden air accumulation in water supply systems can function like invisible "water hammers," potentially causing irreversible damage to pipelines and compromising both water delivery efficiency and quality standards. The solution to this persistent challenge lies in advanced engineering solutions that ensure stable system operation and pure drinking water.
The AVK 851 Series Double Orifice Air Valve represents a significant technological advancement in water infrastructure protection. Designed for potable water and neutral liquids with temperature resistance up to 70°C, this valve combines rapid air exhaust, quick air intake, and automatic air release capabilities to provide comprehensive system protection.
This engineering solution incorporates decades of water industry expertise into its design, offering several critical benefits:
- Rapid Air Exchange: During system filling or drainage, the valve efficiently manages air displacement to prevent vacuum conditions or excessive pressure that could damage pipelines.
- Automatic Operation: The system continuously removes accumulated air during normal operation, preventing air blockages that disrupt water flow and system stability.
- Advanced Aerokinetic Design: A specialized mechanism allows high-velocity air expulsion without premature valve closure, ensuring complete air removal before water activates the shut-off sequence.
- Corrosion Resistance: Iron components feature GSK-certified fusion-bonded epoxy coating, while other materials include WRAS-approved polymers and stainless steel. EPDM rubber seals provide exceptional durability and shape retention.
The product's meticulous design reflects industry-leading quality standards:
- Precision-engineered float mechanism prevents premature valve closure
- High-capacity air flow capability for efficient system operation
- Potable water certification for all fluid-contact surfaces
- Durable EPDM sealing materials meeting drinking water standards
- AISI 316 stainless steel internal components for corrosion resistance
- Non-contact coating design extends protective layer lifespan
- Full compliance with international drinking water regulations
