Cleanliness Filter is recommended for the highest fluid pollution degree;the lowest specific filtration resistance according to ISO 4406(c)20/18/15.

This proportional valve adopts two electrical loops to control perssure and flow of hydraulic system respectively.Using very small pressure drop to track load pressure and control the pump pressure,it is an energy-saving valve.
