Product Description

Product Overview

This piston and cylinder set is a direct replacement spare for the relay valve (item code YHC-0438) on Picanol Omni Plus 800 (OMP800) air jet looms, restoring the relay valve's air switching function during weft insertion. Original part numbers BE311198 / BE312445, our item code YHC-0487.

A matched piston and cylinder pair keeps the relay valve stroke smooth and airtight, so air switching stays fast and consistent, reducing pressure loss and weaving faults over long continuous production.
