China Array manufactures milk meter sensor housings made from Solvay Radel: Polyphenylsulfone (PPSU).
Chemical Resistant: the standard Clean-in-Place (CIP) protocol uses alkaline detergents and an acid rinse at 185 F. Part must also be impervious to milk fat.
Temperature Tolerant: manifold is exposed to temperatures ranging from 1850 F for CIP cleaning to minus 400 F during the night in unheated milking parlors.
Dimensional Stability: plastic bowl connects to stainless top with quarter. Threads must accurately align outlet and claw body.
Clarity: visual inspection of milk flow requires long term transparency.
Impact & Tensile Strength: manifold must stand up to the impact of kicks and drops, as well as the torsion exerted by twisting hoses.
Precise Tolerances: a water tight and vacuum tight seal between the shutoff and the manifold is required to stop milk flow in the event of an unexpected drop off.
Wear-ability: Parts are used up to 20 hours per day 7 days a week in harsh conditions.
