产品概述：

The gate valve is a valve whose gate and valve seat are always in close contact and sealed. Its principle is that there is a circular opening with a diameter on the gate. Through the opening and closing of the gate, the circular opening on the gate is completely separated from and coincided with the diameter. By rotating the handwheel, the screw rod drives the gate to repeatedly move up and down in a horizontal direction, enabling the manual gate valve to achieve the purpose of opening and closing. The advantage of this valve is that the valve body diameter has no grooves, the medium will not be blocked, and has a full bore flow characteristic. Its sealing structure can be divided into soft sealing and hard sealing structures. The penetrating knife gate valve is characterized by precision construction, good craftsmanship, and compact structure. The sealing valve seat is designed as a movable structure, with anti wear and automatic compensation functions, resulting in a longer service life. During the closing and opening process, the valve seat and the gate plate always move closely, making the opening and closing force of the valve stable and characterized by cutting off media.
