1. Summary

The hydraulic valve test bench of model YFS-L is used to perform shell test and seat test of flanged valves,such as gate valves,ball valves,globe valves,check valves etc., welded valves with small size,socket welded valves, screwed valves,etc.,adopting the way of jaw clamping and cylinder goring.Test benches of this model are wild in use,easy in operation,and high in efficiency.
