Main Features and Applications

The PXW series mining water distribution valve is mainly used for water distribution in various suction wells of underground pump rooms in coal mines, and can also be used for mineral processing, water treatment tank discharge, etc.
The PXWI series manual water distribution valve is an improved design based on the original water distribution valve PZ1, with good sealing performance, easy cleaning, and flexible operation
Characteristics such as liveliness and labor-saving.
The PXWI electric water distribution valve is a mining explosion-proof valve electric device added to the PXWI manual water distribution valve, which has a split type and a single type
There are two types of postures:
After being used in conjunction with the KXBC mining explosion-proof valve electric device control box, the split type electric water distribution valve can be connected to the DCS system to achieve
Automation control of underground water pump room in coal mines;
The integrated electric water distribution valve comes with a control system, which can be switched on and off or remotely controlled on the body without the need for a separate control box.
Modbus, Profibus and other bus communication can be configured, with 485 bus interface to achieve data communication.

Instructions for Using Elevation Dimensions

The height difference H between the bottom plate elevation of the water pump room and the inlet elevation of the water tank (or water distribution channel), as well as the length h of the connecting rod, are considered in this design for four different scenarios, and the user unit will choose according to the actual situation. If the value of h can be specified when placing an order, manufacture according to the requirements of the ordering unit. If unable to provide, the length of the connecting rod shall be supplied at h=5000mm, and the flange at one end of the connecting rod shall be welded on site according to actual needs.
