Pantair Autotrol 255 1000250 Valve Disk Kit

What a “valve kit” means

• A valve kit (sometimes called a rebuild kit) typically includes internal components for a control valve: o-rings, flappers/discs, seat assemblies, maybe springs, cam, etc. For example, the website listing includes “Rebuild Kit for Autotrol 255 Valve Body”. 

• It’s used when the valve body has worn parts (disc seals leaking, O-rings perished, etc) and you want to restore operation without replacing the entire valve.

• It’s important that the kit matches the valve model/series of your system. Many kits are specific: e.g., “Valve Disk Kit; 255” is listed in a parts catalogue.
