Z41X rising stem elastic seat sealing gate valve, pressure components are high strength cast iron;The gate plate is coated with glue;The surface is coated with harmless epoxy resin electrostatic spray, which can be used for drinking water pipeline.The valve body adopts no sluice design, which will not cause sludge deposition and is more suitable for sewage working condition.Widely used in tap water, sewage treatment, metallurgy, petroleum, construction chemical, electric power and other industries
1. Integral rubber coating: the gate of rising stem soft seal gate valve adopts integral rubber coating, which has good covering performance and accurate geometric dimension, which ensures reliable sealing and service life.
2. Light weight: the valve body is made of nodular iron, light in weight and easy to install.
3. Flat bottom valve seat: the same flat bottom valve seat design as the water pipe is adopted at the bottom, which does not produce debris deposition, and the sealing is more reliable.
4. Corrosion resistance: the inner cavity of the gate valve is coated with non-toxic epoxy resin to prevent corrosion and rust. It can be used not only for drinking but also for sewage system.
5. Three "0" seal: the valve rod is sealed with three 0-rings, with small friction resistance, light switch and no water leakage.
