TYPE-3 AIRLOCK: CORROSION DUTY ROTARY VALVE

The Corrosion Duty Rotary Valve Type-3 Airlock is our valve with two personalities. Take a standard Type-1 airlock, change the rotor to 304 stainless steel and coat the cast iron endplates and housing with Nedox® chrome; the rotary valve becomes both corrosion resistant and food grade. You get the performance of a stainless steel valve for the cost of cast iron.

All of our rotary valves are NFPA Section 12.2.3.2 compliant.
