BOOSTER PILOT VALVE |
摘要 |
<p>A booster pilot valve operable at ultra low power levels is provided. The booster valve includes a moveable spool capable of directing a fluid flow to at least two different paths. The booster valve may be coupled to a piezotronic three-way valve, which controls the movement of the spool by redirecting a main fluid flow along different paths to create a force on the spool. The piezotronic valve is capable of actuation at very low power levels such as might be provided by a Profibus PA or other Bus system.</p> |
