Bar manifolds are machined and undergo stress relieving heat treatment after mechanical processing. They are then assembled with automated processes and tested individually. A complete set of sizes are available, with versions and accessories for control of the single ways. They can be purchased pre-assembled on standard or lowered brackets in delivery/return kits. Numerous accessories complete the manifold with all components required for optimal system operation: ball shutoff valves, air purge valves, filler-drain valves, bypass valves, housing cabinets and individual isolation.
