摘要 |
<p>The valve comprises an elongated valve body having a process fluid inlet and a process fluid outlet. An elongated valve stem is disposed within the valve body for axial displacement relative to adjust a rate of process fluid flow between the fluid inlet and fluid outlet as a function of a relative axial position of the valve stem with respect to the valve body. A cam is disposed within the valve body coupling the valve body and valve stem. The cam provides axial displacement positions to place the valve stem at a selected one of relative axial positions with respect to the valve body. The valve body has a control fluid pressure port for allowing a control fluid pressure to be introduced into and released from the valve to reciprocate the valve stem axially with respect to the valve body between cocked and set positions.</p> |
