HYDRAULIC VALVE |
摘要 |
<p>A pilot actuated hydraulic control valve has a flow setting member in the form of a valve piston an end of which co-operates with radial outlet ports of the valve to form a variable metering orifice. A flow sensor provides a feedback differential pressure proportional to the flow through the valve and that feedback differential is used to control a pilot stage which actuates the flow setting member.</p> |
