Check Valves: AVFI specialise in a wide range of check valves (Non Return Valves) include tilting disc, swing type with lever and counter weight arms, wafer check, duo check, single flap check, flex check valves and ball check valves. Where stated, AVFI’s check valves comply with Australian Standards AS 4794, our check valves range in sizes from DN 10 (10 mm) to DN 1200 (1.2 metres) and pressure ratings vary from PN 6 (6 bar) to PN 40 (40 bar). Stocked check valves are available in a variety of materials such as cast iron, ductile iron, stainless steel, PVC and FIP thermoplastics. Positioners, limit (open/close) switches and relays can be fitted to check valves (non return valve) to suit order requirements.
