Valve Testing
  Valve Grinding
   
  Description： Hydraulic Butterfly Valve Test Bench
  Model： YFS-DL
Testing Range： DN50-1600
Testing Medium： Water,Gas or Oil
     
 
 

1. Summary

The hydraulic butterfly valve test bench of model YFS-DL is used to perform shell test and seat test of butterfly valves. As for the way of loading and clamping of the valve to be tested, the test bench adopts the way of pulling downwards of the clamping jaw. As for the form of configuration, the test bench can also be designed into two types, unitary type, that is, one hydraulic station controls one workbench, and set type, that is, one hydraulic station controls two workbenches. The appropriate type of test bench will be selected, designed and manufactured according to the customers′ requirements of testing pressure range.
