Bevel gear stainless steel gate valve

Bevel gear stainless steel gate valve

Gate valve, also known as gate valve or gate valve, is a widely used valve. It controls the opening and closing of the valve by lifting and lowering the gate. The gate is perpendicular to the fluid direction. Changing the relative position between the gate and the valve seat can change the channel size. The gate valve has the following advantages: 1. The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium. 2, opening and closing:
