Lift Type Plug Valve
Product Description The metal hard seal lifting plug valve uses the first lifting and closing valve operation mode, which greatly reduces the opening and closing torque of the cock valve, and is different from the traditional cock valve using the rectangular diameter channel. The valve usually...
The basic principle of lifting plug valve is to make the plug rise when it is opened, and the friction between the plug and the sealing surface of the valve body can be reduced when the plug rotates 90 degrees to the full opening of the valve; and the plug can rotate 90 degrees to the closing position when the valve is closed and then descend to contact the sealing surface of the valve body to achieve sealing.
