Main Features And Advantages Of Gate Valve

- Nov 11, 2017 -

Main Features

Light weight: The main body is made of advanced ball black cast iron, the weight of the traditional gate valve to reduce the weight of about $number, installation and maintenance convenience.

Flat-bottomed gate: traditional gate valves are often used for external objects, such as stones, after washing pipes block, cement, iron filings, sundries, etc. deposition in the groove of the valve bottom, easy to cause close and can not shut down the formation of leakage phenomenon, elastic seat seal valve bottom with the water pipe with the flat-bottomed design, not easy to cause debris siltation, so that the fluid unimpeded.

The whole package: The Floodgate board uses the high quality rubber to carry on the whole inside, the external rubber, the European first-class rubber vulcanization technology makes the vulcanization board to be able to guarantee the accurate geometrical size, and the rubber and the ball ink cast the floodgate board then securely, is not easy to fall off and the elastic memory is good.

Precision Casting Valve Body: The valve body uses the precise casting, the precise geometrical size makes the valve body inside without any finishing can guarantee the valve the tightness.


1. Small flow resistance. The internal medium channel of the valve body is straight through, the medium flows in a straight line, the flow resistance is small.

2. The opening and closing time is more labor-saving. is compared with the cut-off valve, because whether it is open or closed, the movement direction of the gate is perpendicular to the medium flow direction.

3. Large height, long opening and closing time. The gate opening and closing stroke is larger, the drop is through the screw.

4. Water hammer phenomenon is not easy to produce. The reason is that the shutdown time is long.

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

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

7. The form is simple, the structure length is short, the manufacture craft is good, the scope of application is wide.

8. Compact structure, good rigidity of valve, smooth channel, small flow resistance, dense cover with stainless steel and cemented carbide, long service life, using PTFE filler. The seal is reliable. The operation is lightweight and flexible.
