Operation method

The valve clack is automatically opened and closed under the medium force to prevent flowing to another direction.

Application fields

For application in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, etc.

Other remarks 1

Due to loading of spring, the valve clack can move flexibly without jamming, and has a good sealing performance.

Other remarks 2

Built-in pin roll, without external leakage point

Other remarks 3

Suitable for medium backflow prevention in pipeline or device

Other remarks 4

tShort closing travel of valve clack, and small impact at valve closing; short structural length, most suitable for positions with limited mounting spare

Other remarks 5

The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.

Available retainer type and retainerless type

Retainerless design is used in wafer,flange,lug and hub-end body style.Compared to retainer design,the retainerless deisng can provide

1- High integrity

2- No thread corrosion risk(retainered design has screwed body plugs)

3- No plug blow out risk

4- Easy disassembly
