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.
