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.

Variant 701/96-010
Connection: External BSP Thread
Material: Stainless steel
DN: DN50 - DN80
PN: PN16

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
