简介：

leakage is quite small and there is no worry about hydraulic lock.

because of the residual air in the valve.

These valves are used for opening/closing the oil path 

At the time of test run, there is a possibility 

that the oil may not flow even after the solenoid is energised 

by having the poppet v alve operated with an electric signal via solenoid.  

Because these are of poppet type, the internal
