The Shako solenoid coil retaining nut and spring washer set is designed to securely retain the solenoid coil on compatible Shako PU220 and PU225 Series valves and other valve assemblies using Nass Magnet System 13 armatures.

Supplied as a set of 1 retaining nut and 1 rectangular spring washer, these components are ideal for solenoid valve servicing, coil replacement, refurbishment and maintenance stock.

The standard version uses a nickel-plated steel M10×1mm locking nut together with a rectangular zinc-plated spring washer. An optional 304 (A2) stainless steel M10×1mm retaining nut is also available for applications requiring improved corrosion resistance.

The spring washer maintains tension against the solenoid coil, helping keep the coil securely positioned on the armature tube during normal valve operation.

Suitable for Shako PU225, SPU225 and PU220 solenoid valves from 3/8" to 2", as well as compatible valves fitted with Nass Magnet System 13 armature assemblies.
