The ShearFlo® SV-12 directional control valve ensures negligible internal leakage and contaminant resistant operation for 1/8” piping. Its modular design allows for various operator and porting options to suit numerous high-pressure critical service applications. The current operator options are standard manual and spring centered. For remote operator options, reach out today for a custom tailored solution.

The manifold mount option has been designed to be compatible with the D03 pattern. This is advantageous to use existing manifolds for replacement of other D03 congruent valves. PacSeal is also a specialist in manufacturing custom hydraulic manifolds, which decrease overall costs, assembly time, footprint, and leak points, while increasing flow rate potential and ease of maintenance. Check out our options of integral control valve manifolds to see the possibilities with designing your next hydraulic control system.
