AVK COMBINATION AIR VALVE, PN 10

For wastewater, reinforced nylon, compact design

Short combination air valve 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 deliberated 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.

Variant 701/75-010
Connection: External BSP Thread
DN: DN50 - DN100
PN: PN 10

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 foamed 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 nylon 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 in the 1 1/2" threaded opening on the top of the valve

With connection flange or 2”-3” BSP thread

Working pressure range: 0.2 – 10 bar
