EDCO Switch Machine

DA-10 Switch Machines have been around for several decades with only minor updates, primarily in the solenoid valve configuration. 

EDCO USA took a fresh approach to the overall design in order to create an entirely new direct interchange Switch Machine that would meet performance requirements while using modern material and construction methods.

For exceptional reliability, rugged, hand-lapped, bronze slide valves on hardened steel seats are used for both main and pilot valves which have been tested down to -65º F. Model Z-067B provides a drop-in interchange for DA-10 Switch Machines.
