Threaded Spool Valves

The construction adopted for the spool system allows for extremely unique performance. The valve is made of only two parts, body and spool (in one piece), with fluctuating seals of a special compound that reduces friction and prevents sticking. These features—along with a high flow capacity and the absence of communication between the chambers—make maintenance easier, lubrication unnecessary, and allow for a high cycle life. Apart from the typical uses of the spool system, this valve is also suitable for vacuum application, for 5/3 open or closed centers.
