| NON-RETURN VALVES are specified by adding “R” after the basic pump number (AXM1NR). They are often used to prevent manifold exhaust air from flowing into inactive pump segments Non-return valves must not be used for safety circuits.
VACUUM SWITCH OPTION: Add suffix “S” for a V-3 style switch mount and order VN-3 or VP-3 Switch as a separate line item. Electronic switches do not travel well when assembled to the manifold assembly so they should be attached just prior to installation.
DIGITAL VACUUM SWITCH OPTION: Add suffix “DS” for a digital switch mount and order the DVN61-4, DVP61-4, DVN62-4, DVP62-4, DVN602-4, or DVP602-4 Switch as a separate line item. Electronic switches do not travel well when assembled to the manifold assembly so they should be attached just prior to installation. EDCO will attach the proper mount to the switch to make the job as simple as possible.
MANIFOLD END PLATES: Each manifold assembly requires a set of end plates and tie-rods of the correct length, as designated by the number of pump segments in the assembly. Order End Plates as a separate line item. For example: EN-4 would be for a 4-segment assembly with NPT ports, and EG-6 would be for a 6-segment assembly with BSPP ports. Manifolds can be built with any number of segments between 1 and 10. Both end plate includes a ¼” air supply and a ½” pump exhaust port.
