Heavy Duty Rotary valves Airlocks & Feeders for Challenging Applications Anval RH series heavy Duty Rotary valves can serve to an extensive range of applications from heavy minerals industries to light agricultural applications, even under harsh operating conditions. RH Series heavy Duty Rotary valves are designed for use in a wide range of applications from heavy mineral lumps to light dust. Unlike our competitors, the RH Series valves are in single piece cast construction reducing the number of seams for wear. These valves operate under the toughest conditions with minimal maintenance.
The “labyrinth seals” ensures perfect sealing of rotating shaft thus ensures zero leakage through shaft ends. These labyrinth seals even effective with highly abrasive products and also when there is high pressure across the system.
In addition, these valves have all of the advantages of Cast Iron over traditional mild steel including superior corrosion resistance, better wear properties and thermal stability. RH series valves are also available in Cast Steel, other alloys to deal with high temp, high wear and high-pressure environments; regardless of the application required. RH series valves are available in opening sizes from 150mm – 750mm and also available in Direct driven, Chain driven or in Bare Shaft arrangement. These valves can also be customized to suit the specific application requirements. These valves are best suitable for industries ranging from Chemicals, Food, Steel, Cement, Wood, Power to Mineral processing plants.
