1. Summary

The hydraulic valve test benches of model YFS-L series are used to perform shell test and seat test on flanged end valves, welded end valves, socket welded end valves and threaded end valves with size below DN300(12"), such as ball, gate, globe and check valves etc., adopting the way of jaw clamping on the bottom and thrust oil cylinder clamping on the top. The test benches of this model are wide in use, easy in operation,and high in working efficiency.
