AVK LARGE COMBINATION AIR VALVE, PN 16

Description

Key Features

• Orifice sizes: Automatic 16 mm2, kinetic 5024 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.
• Unique design of the float assembly prevents contact between the wastewater and the sealing mechanism, prevents clogging by floating solids and ensures drip-tight sealing.
• The disc is placed at the top of the valve, keeping the levers and pins away from the corrosive atmosphere in the air valve body.
• The stainless steel float system 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 epoxy coated steel body features low weight.
• Drainage and flushing is possible through the drain in the valve’s side.
• An exhaust tube can be mounted in the threaded opening on the top of the valve.
• The outlet enables removal of excessive fluids.
• With connection flange.
• Working pressure range: 0.2 – 16 bar.

Information

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.

Test/Approvals

• Hydraulic test according to EN 1074-1 and 4 / EN 12266.
• Approved for wastewater
