The 4-way distributors with manual control of the 4L series are specifically designed for high pressure applications.
The distribution system is of the balanced drawer type, so that the drive effort is not influenced by the pressure value.
The distributors are available in the spring version for spontaneous return of the lever to the center or with a jerk device to hold the lever in the desired position. Two internal connection diagrams are available between the ports in order to satisfy any system requirement.
The discharge mouth S can withstand the maximum pressure allowing the series connection of several distributors in execution A (open center).
Distributors can also be supplied in special execution for specific use in shipbuilding.
