The gate valve of Z961Y power station is mainly used as the opening and closing device on the water and steam pipeline. It is used to cut off or connect the medium in the pipeline. Use should be fully open or fully closed, can not be used as regulating valve. Gate valve works: according to the clockwise rotation of the hand wheel or stem nut, stem driven gate down, so that the sealing surface anastomosis, cut channel, that is closed; otherwise, is opened.
Note: parameters are for reference only or are incomplete. The valve can be selected according to requirements of different pressure, material, caliber, drive mode, etc.. Please contact or consult online.
Order note:
If there is no selected model, please provide detailed parameters, such as medium, temperature, pressure, caliber, material and so on. Our technicians will select for you
Two. Provided that the selected model is available according to the selected model
Three, non standard products need to provide samples or confirmed by drawings
Note: the information is for reference only, or incomplete, so please feel sorry for the inconvenience. The company can choose according to different requirements and parameters. The company has a variety of sizes, pressure, different materials, connections, drive mode, to meet the different needs of various types of gate valve. Please contact 021-6651 8677 or consult online.

All sealing pairs of valves are made of Stellite hard alloy welded by different hardness. The sealing pairs are reasonable and the sealing performance is good. They are resistant to high temperature, high hardness, abrasion resistance, erosion resistance and long service life.
The upper sealing surface is made of austenitic stainless steel or Stellite hard alloy, and the sealing is reliable and corrosion resistant. The replacement of packing can be carried out without stopping the machine, and the operation of the system is not affected.
The body lid adopts a pressure tight sealing structure, and the higher the pressure, the better the sealing performance.
Gate valve adopts double ram or flexible gate structure, reliable sealing, flexible action, convenient maintenance.
The connecting part of the stem nut and the bracket is provided with a thrust ball bearing, the rotating moment is small, the opening and closing is flexible, and the labor saving and electricity saving are realized.
The electric device selects famous brand products with the advantages of small size, light weight, complete function and reliable performance. It can also be used in conjunction with a program controlled computer for long distance operation.
1. 、 the pressure self tight seal is adopted, and the ends of the valve body and the branch pipe are welded together.
2. valve seat, valve sealing surface using cobalt based carbide plasma spray welding, wear resistance, good resistance to abrasion.
3.. The valve stem is resistant to corrosion and nitriding. It has good corrosion resistance and scratch resistance.
