Bellow Sealed Globe Valve with Cast Steel

Bellow Sealed Globe Valve acc. To DIN is applicable to the cutting and connection of 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 ~16 MPA and

working temperature is -29 to 350 °C.

Main Structure Feature

1. The 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 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 meeting the requirement of various

 engineering.
