Load Sensing Electro-Proportional Directional Valve

· Monoblock design and leakage free.
· The manifolds is never worn and maintenance free.
· Driving directly by electromagnetism, the control will be as you wish.
· Flexible layout in one single manifold let it possible to quickly customize in high volume.
· With the precise matching of the spool and the sleeve, the manifold can be manufactured with aluminum profile from the market, without the precision casting and precision machining, to meet the demand of the rapid change of the rapid changing market.
