Name:Bellow seal DIN globe valve

Product structural features:

Parabola bellow seal globe valve acc.to DIN is applicable to the pipelines medium that are used in various industries such as petroleum.chemical industry,pharmacy,chemical fertilizer,electric power industry etc under nominal pressure of PN1.6~16MPa and working temperature of -29~350℃ as swithch and the adjustment of fluid.

Main structural features:

1.This product has logical structure,reliable seal ,excellent performance and nice design.

2.The seal surface is build-up welding with Co hard alloy,which is attrition-resistant,corrosion-resistant,has good friction resistant and long life.

3.The stem is quenched and tempered,and its surface is treated by nitriding treatment,thus it has good corrosion resistant and friction resistant.

4.It has double seal capability,thus is more reliable.

5.The stem may show the position of lift,thus it is clearer.

6.The part material,flange and butt weld end dimension may be selected according to current operating condition and users'requirement,so that meet the requirements of various engineering.
