Rotary Floating Shoe Valves

RFS Rotary Floating Shoe valves provide unmatched performance as airlocks in high wearing applications. This RFS series can last up to four times longer than traditional rotary valves.

THE TOUGHEST AIRLOCK OR METERING SOLUTION FOR HIGH WEARING PRODUCTS

Rotary Floating Shoe or RFS Valves form an important part of the Anval range of materials handling valves. RFS Valves are rotary valves specifically designed for high wear applications.

The valves can be used in both positive and negative pressure applications and consist of a main body with bolt-on side plates and a rotating, webbed rotor located in between.

Technology

To achieve 100% positive sealing, the Anval RFS Series Valve has a "FLOATING SHOE"' which slides tightly into the main body top port flange and rides onto the rotor by gravity force. The shoe slide is sealed with a double 'O' ring between the shoe and the main body, and where the shoe rides on the rotor, the contact surface between the two parts forms a mechanical seal.

Features

The Anval RFS Series also feature a sacrificial, hardened SG iron adjustable shoe. The shoe, which sits on the rotor, has up to 10mm of wear and can be adjusted externally while in operation to maintain minimal clearance at all times.

Long Service Life

The long service life that distinguishes Anval RFS valves from all other valves in the market is achieved through the ceramic tips embedded in all leading surfaces of the blades and end plates of the rotor.
