Non-rising stem knife gate valve have a stem nut on the disc,when turn the stem by hand,the disc will go up and down with the stem nut,this design used where the installation space is limited.

We have some large diameter knife sluice gate valve body in stocked,so we can provide short lead time for our customers.

All the flange knife gate valve will tested one by one before shipping,test according to API598 GB/T13927 ext.
Body test 1.5*PN,seal test 1.1*PN, if the knife gate valve is bi-directional, then we will test two side of seal.

The Grooveless knife gate valve is also called bidirectional sealing knife gate valve. The ductile iron valve body adopts integral structure knife gate valve, including valve body, disc and U-shaped sealing strip. The left and right sides of the valve body and the bottom of the middle cavity are provided with grooves and elastic U-shaped sealing strip. When the valve is closed, the disc moves down, The bottom edge of the ram contacts with the sealing strip, and the sealing strip is compressed into the groove to realize the sealing of the valve body and the ram; When the knife gate valve is opened, the ram moves up, the bottom edge of the ram is separated from the sealing strip, and the sealing strip springs up and the groove is flat, which can prevent the medium sediment from depositing in the groove of the middle cavity of the valve body during the use of the knife gate valve, which is not easy to block and has no residue, and the pipeline is easy to clean, so as to effectively improve the sealing effect of the knife gate valve and prevent leakage when the valve is closed.
