CONTROL VALVE |
摘要 |
<p>A guided control valve comprising a vapor recovery area that encourages collapse of vapor bubbles. In a cage-guided valve, a seal comprising inner and outer members reduces flow through a radial clearance between a plug and a cage. The vapor recovery area is positioned below the seal and above a seat interacting with the plug. The vapor recovery area encourages collapse of vapor bubbles to reduce damage to the valve trim.</p> |
