Improvements relating to fluid flow control apparatus.

摘要

This invention provides a manifold arrangement for complex plumbing systems for example car wash apparatus in which a bank of solenoid valves (14) is fixed to a common manifold (10) by tubular bolts (40) arranged to connect fluids for flow from the manifold interior via the valves, or across the manifold not communicating with the manifold interior, or both. The valves are servo-closed by line pressure. <IMAGE>
