03.Features
001. Integral laminating: the valve adopts integral laminating, with good covering performance and geometric size, ensuring reliable sealing and long service life.
002. Light weight: the valve body is made of ball iron, light weight and easy to install.
003. Flat valve seat: the same flat valve seat design as the water pipe is adopted at the bottom to avoid sundry deposition and provide reliable sealing.
004. Corrosion resistance: the inner cavity is coated with epoxy resin to prevent corrosion and rust. It can be used not only for drinking, but also for sewage system.
005. Three "O" seal: the valve is sealed by three o-rings, with small frictional resistance, light switch and no water leakage.

07.Operating principle
Gate valve by valve body, valve cover, disc, stem, seat, stents, such as the sealing parts. gate structure classification of many.When the handwheel (or other driving device) rotates counterclockwise, drive the stem nut to rotate, then the stem nut drives the stem to rise, the stem drives the gate to rise upward, until the gate is fully opened, then the medium at both ends of the valve body channel flows;When the handwheel turns clockwise, the stem nut drives the stem down, thus driving the gate down, until it is completely closed, then the valve body channel medium stops the flow.
