Technical Feature
OPERATION
In its steady state, the valve blocks flow from port ② to port ③ ,until either the
predetermined spring setting has been reached at port ② , or an external pilot has
been applied to port ① . At this time flow is then allowed from port ② to port ③ .
Since the spring chamber is vented at port ③ , back pressure at port ③ will directly (1:1)
effect the valve setting. -
