Air valve for wastewater AVK

Short combination air valve - PN 10 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 orifice in the automatic valve releases 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 reinforced polyamide 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 top of the valve
• With connection flange or 2”-3” BSP thread
• Working pressure range: 0.05 – 10 bar
