Pilot Oil Source, Pilot Control Valve Block for Excavator

XDYY Pilot Oil Source
Application 
This product is applied to the control circuit of a hydraulic system and changes the flow direction of oil line through the solenoid directional valve so as to meet the requirements on working conditions of the system. This kind of valves is widely used by all types of excavators, construction machinery, minning machinery, farm machinery. 
 
Functions and features 

1. Thread cartridge solenoid valve, check valve and accumulator contribute to a compact structure and easy maintenance; 
2. A check valve is added at the oil inlet to maintain the pressure of the whole control circuit and also avoid shock of system press from control circuit to the control pump. 
3. Accumulators can be used to ensure pilot pressure stable; 
4. Spool can provide different matching range according to customer requirements; 
5. The modular design; 
6. Functions of valve manifolds can be extended according to customer requirements.
