Robust, high efficiency and versatile design, all for handling bulk materials with various properties and applications. This “Single piece” cast design can handle a maximum capacity of about 469 m³/hr with higher temperature.


RH Wired ModelAnval RH series rotary valves can serve to extensive range of applications from heavy minerals industries to light agricultural applications, even under harsh operating conditions.

Our products and solutions have proven themselves across a wide range of industries and in some of the most demanding manufacturing environments. We are proud to be the prescribed suppliers of valves for some of the world’s biggest mining companies.

RH series valves are available in opening sizes from 150mm - 600mm. Unlike our competitors, the Anval valve bodies are fully cast in a single piece reducing the number of seams for wear. In addition, as all of the components are manufactured from cast iron the valve has all of the advantages of cast iron over traditional mild steel including superior corrosion resistance, better wear properties and thermal stability.

Sealing Method

Perfect sealing is definitely required on the rotating shaft and Anval rotary airlocks adhere to it by using "labyrinth seals". To seal dust and achieve smooth operation, dust tight seal on a rotating shaft is required. These labyrinth seals even effective with highly abrasive products and also when there is a differential pressure.


Anval RH Series valves can be fully customised and can be fabricated to suit applications, thus allowing customers to choose product of their choice. RH series valves are best suitable for industries ranging from chemicals, food, steel, cement, wood, steel, power to mineral processing plants.
