1 Catalog HY14-255/US Series VY*K General Series VY*K pilot operated sequence valves feature proportional adjustment and an external drain. The external drain allows application as both a sequence valve and as a pressure relief valve. These valves can also be used as a pressure relief valve. Please observe hydraulic connection. Features Proportional adjustment. Manifold mounting acc. to ISO External drain. Main stage spool type valve. Pilot stage seated type valve.
