4WMM16G solenoid valve

WMM type manual reversing valve is a direct-acting reversing slide valve that moves the spool axially through the rotation of the handle to switch the oil circuit. It has multiple slide valve functions of two-position three-way, two-position four-way and three-position four-way, and can choose positioner and spring return device. Using plate connection.

4WMM*****/type
The valve is composed of one or two return springs and push rods, which are controlled by the handle of the valve body.
When the handle is displayed, the spool is held in the neutral or initial position by the return spring. When the handle is pushed right or left, the handle pushes the push rod through the hinge and directly controls the spool, and the spool moves to the required position to obtain the required flow section. When the handle returns to the zero position, the control spool returns to the normal position by means of the return spring. The switching device of this valve is determined by handle manipulation.

4WMM***** /F type
The principle is basically the same as that of WMM******. But this type of valve is a control valve with two or three switching positions and a positioner so that all switching positions are fixed.

Cartridge damper:
Due to the limitation of working conditions, the flow rate may be greater than the value on the performance curve during the switching process, and a cartridge damper needs to be installed in the P oil circuit of the control valve.
