TRANSFER VALVE MANLFOLD

摘要

A manifold (1A) that simultaneously supplies a control and pilot fluid to a transfer valve (2) has an internal pilot channel (8) leading to a supply port (4); an external pilot channel (13) leading to an external pilot port (X1); and a shuttle valve (11) that selectively guides a pilot fluid to the pilot valve (20) from the internal (8) and external (13) pilot channels. Two input openings (11a),(11b) in the shuttle valve (11) are individually connected to the pilot channel (8) and external pilot channel (13), while the output opening (11c) is connected to the pilot supply channel (6).
