PRODUCT CENTER

The gate valve's opening and closing part is the gate. The movement direction of the gate valve is perpendicular to the flow direction. The gate valve can only be fully opened and fully closed. The two sealing surfaces form a wedge. The wedge angle varies with the valve parameters, usually 5 ° and 2 ° 52 'when the medium temperature is not high. Improve its processability, make up for the deviation of sealing surface angle in the process of processing. This kind of ram is called elastic ram.

It is easy to open and close. It is compared with the stop valve, because whether it is open or closed, the movement direction of the gate is perpendicular to the flow direction of the medium.

Large height, long opening and closing time. The opening and closing stroke of the gate is large, and the lowering is carried out by the screw. Water hammer is not easy to occur. The reason is that the shutdown time is long.

The medium can flow in any direction on both sides and is easy to install. The gate valve channel is symmetrical on both sides.

The length of the structure (the distance between the two connecting ends of the shell) is small.

The utility model has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.

Compact structure, good rigidity of valve, smooth channel, small flow resistance, sealing surface of stainless steel and cemented carbide, long service life, PTFE packing, reliable sealing, light and flexible operation.
