WMM manual reversing valve is a direct-acting reversing slide valve that switches the oil circuit by rotating the handle to make the valve core move axially. It has multiple slide valve functions such as two-position three-way, two-position four-way and three-position four-way, and can choose positioner and spring return device. It adopts plate connection.
WWM.../type
The valve consists of a valve body (1), a handle (2), a valve core (3), one or two return springs (4) and a push rod (5).
In the non-operating state, the valve core (3) is held in the middle or initial position by the return spring. When the handle (2) is pushed to the right or left, the handle (2) pushes the push rod (5) through the hinge and directly controls the valve core (3), and the valve core (3) moves to the required position, thereby obtaining the required flow section. When the handle returns to the zero position, the control valve core returns to the normal position with the help of the return spring. The switching position of this valve is determined by the operation of the handle.
WWM.../F type
The principle is basically the same as the WMM... type. However, this type of valve is a control valve with two or three switching positions and a positioner. Therefore, all switching positions are fixed.
Insert damper
Due to working conditions, the flow rate may be greater than the value on the performance curve during the switching process, and a plug-in damper needs to be installed in the P oil circuit of the control valve.
