Rotary Valves & Feeders

HEAVY DUTY ROTARY VALVES MANUFACTURE OR REPAIRED.

SUITABLE FOR THE HARSHEST ENVIRONMENTS.

Avweld have been at the forefront of innovation in the repair of rotary valves for many 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 Rotary Valves in Australia, offering everything from simple rebuilds to complete redesign. 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 2500m. 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.

Large volumes during short shuts are not a problem as we work around the clock to minimise plant downtime. All work is carried out in our Melbourne facility so quality and work flow are under strict control to ensure you get what you need, when you need it.

Avweld are able to design, repair and manufacture the complete range of rotary valves from 100 x 100mm up to 2000 x 2000mm. We are able to offer advice on the selection of particular components and setups. Both light and heavy-duty rotary valves can benefit from Avweld’s expertise.
