Pilot-operated directional control valve |
摘要 |
An internal pilot channel branching from a supply port, an external pilot channel leading to an external pilot port, and a pilot input channel for guiding a pilot fluid to a pilot valve are opened in parallel on a channel-switching surface formed in a body. A channel-switching plate having a dent large enough to extend across the openings of two adjacent channels is mounted on the channel-switching surface in such a way that its direction can be changed by 180 DEG .
