The valve is suitable for two or more single-acting cylinder, or the double-acting
cylinder.




Reversing performance test






When voltage is 198V, oil pressure 4MPa, reversing of the valve performance is good.





When voltage is 198V, oil pressure 4MPa, internal leakage≤0.3MPa/Min




overflow performance testing: When start drip oil, oil pressure≥4MPa; overflow pillars, oil pressure≤5Mpa





Regulating performance testing: when the oil pressure of 4 mpa, the regulating valve can adjust output flow rate or close it.








Sealing performance testing: the body of valve shall not leak oil.





Insulation and suffer voltage test: AC1500/second


For floor drain current, normal<0.10mA, single<0.20mA





Conclusion: Qualification or failure
