The role of plastic extruder reversing valve

For plastics extrusion machine, one of the most important part is the directional valve. To this end, the following small ooze to introduce the specific functions of the reversing valve under:

When plastic 65 moved to the left of the pilot valve, reversing valve at the left and the pressure oil unicom, at the same time to cut off the plastic material production equipment and the plastic material production equipment unicom plastic material, plastic extrusion machine left side reversing valve and the oil through groove plastic material production equipment, pipe flow back to the tank.

At the same time, move the reversing left plastic extruder directional control valve. When reversing valve reversing left cut off the plastic material production equipment, production equipment and plastic profile cutting off the valve in this connection, the cavity and B valve is connected, so the maximum working pressure is determined by the B valve, make the plastic sheet extruder system back to normal working pressure.
