 The electro-hydraulic SERVO VALVE G772K620A has better control when used for four-way valves. This series of valves is a high-performance two-stage electro-hydraulic servo valve with a valve core and valve sleeve, equipped with a standard 4-core electrical socket. The four leads of the torque motor are all located at the socket. The system recommends a cleanliness level of ISO 4660<14/11, and a long service life recommendation of ISO 4660<13/10. The specific parameters are as follows:

 
Weight: 1.1KG
 
Rated flow rate: 63 lpm
 
Resolution:<0.5%
 
Permissible working pressure: 32MPa
 
Normal working pressure: 14MPa
 
Working temperature: -29~135 ℃
 
Sealing material: fluororubber
