Short combination air valve - PN16 for wastewater treatment to max. 60°C (temporarily up to 90°C)
AVK combination air valves are designed to combine large volume of air discharge/intake whilst filling/draining a pipeline with automatic discharge of air from the fluid. They feature an innovative design with a large air gap between liquid and sealing system. A spring between stem and float compensates for slight pressure changes and maintains the air gap ensuring reliable function even when used with aggressive liquids and liquids carrying solid particles.

Features
- Orifice sizes: Automatic 12 mm², kinetic 804 mm²
- The large air gap between liquid and sealing system ensures a reliable function even when used with aggressive liquids and liquids carrying solid particles
- The large orifice in the automatic valve releases large volumes of air when the line is under pressure
- The spring between the stem and upper float compensates for slight pressure changes
- The lower float system with float of polypropylene and stem and spring of acid-resistant stainless steel ensures high corrosion resistance
- The conical body with funnel-shaped lower body allows maximum air volume within minimum valve length and prevents accumulation of deposits at the bottom
- The body of stainless steel features low weight
- Drainage and flushing from external clean water source is possible through the drain in the valve’s side
- An exhaust tube can be mounted on the quick connector at the valve
- With 2”-3” BSP thread
- Working pressure range: 0.05 – 16 bar
