Gate Valves are called "full-flow" Valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.

    Our blades was made from high quality steel,which was produced by China famous steel factory which means our blades will have al longer time.We do a lot of experiment to create an alloy formula which can improve the performance of rotary blades.And with individual deposition techniques our product have obvious advantages on the quality of agricultural blades.
