Avweld Heacy Duty Rotary ValvesGet latest price

Avweld have been at the forefront of innovation in the repair and manufacturing of rotary valves for over 30 years. Some of our improvements include reduced rotor to stator clearance, modified sweepers for reduced blocking on end plates, spring loaded seal rings and upgrading of hardfacing of both rotor vanes and stator bore.

We are paramount in the repair of Heavy Duty Drop-Through and Blow-Through Rotary Valves in Australia, offering everything from simple rebuilds to complete overhaul. The most significant features of our upgrades are AV100 Tungsten Carbide coating of the stator bore, hardfacing of rotor tips and spring loading of the seal rings. These improvements have given an increase of 4-8 lifetimes over hard chrome bores and 420SS vane edges. We have achieved our number one position by offering quick turnaround, top quality, state-of-the-art upgrades all at modest prices.

We repair all sizes from 100mm to 2000mm. Typical turn around is 4 to 6 weeks but repair can be done in as little as 5 -10 days if required. Currently Avweld are performing a complete overhaul of over 200 rotary valves per year.
