1) The upper seal of the valve is sealed by three "O"-shaped rubber sealing rings, and the upper two "O"-shaped rubber sealing rings can be replaced without stopping the water.
2) The valve body and bonnet adopt "O" type rubber sealing ring structure, which can realize self-sealing.
3) When the valve is fully open, the valve plate is higher than the diameter of the valve, the bottom of the valve body is smooth without gate groove, and the flow resistance coefficient is small, which avoids the phenomenon that the valve plate is not tightly sealed due to debris blocking the gasket.
4) The valve stem nut and gate plate are connected by T-slot, which has high strength, and the radial friction force between the valve plate and the valve body is very small, and the service life is long.
5) Anti-rust and anti-corrosion treatment adopts electrostatic spraying of non-toxic epoxy resin hot-melt solidification powder. The powder has WRAS and NSF certification, which eliminates secondary pollution to water quality and makes water supply more pure.
