Since 1964 the PERMA/flo Extreme Rotary Valve has been considered the valve of choice by customers who demand long life, rugged durability, ease of maintenance and high quality.
The Extreme Rotary Valve, can be applied as rotary feeders & airlocks. The Extreme series of rotary valves feature a unique design that offers external field adjustment between the rotor and the seal/wear shoe.
Both the rotor and seal shoe are constructed of a special chrome-iron alloy called P-33. This alloy yields a hardness of 500-600 Brinell. Unlike other valves that feature a surface hardening, P-33 is a solid alloy casting that does not wear off to expose a softer metal base.
