Valve Testing
  Valve Grinding
   
  Description： Hydraulic Valve Test Bench of model YFS-D
  Model： YFS-D
Testing Range： DN15-1200
Testing Medium： Water,Gas or Oil
     
 
 

1. Summary

The hydraulic valve test benches of model YFS-D series are particularly designed to test welded end valves.The test benches equipped with special sealing plates and leak detection assembly can perform shell test and seat test on welded end valves. Besides, they can also be used to test flanged end valves, socket welded end valves, screwed end valves etc. As to test high or super high pressure valves,the test bench can be particularly designed and manufactured according to customers′ special requirements.
