With the rollout of our new website this month we will also be introducing Youli valves as our newest product line. Youli valves are rated up to 4600 PSI and flows to 63 GPM. Monoblocks are available with up to seven spools in the MB-3, or six spools in all other monoblocks. Sectionals can use up to 12 spools in an assembly. All are power beyond or closed center capable and can be manual, pneumatic, hydraulic or electrically operated.
