Introduction

Forged steel bellows globe valves are generally of small diameter, from DN15 to DN50.

It can be used in some high-pressure steam pipelines.

 

Advantage

Why forged steel bellow seal globe valve more better in high pressure steam pipelines?

1, Forged steel bellow seal globe valve purchased forging process.


The process of forging is better than that of casting, but the cost will be higher.

2, The Forging progress has no sand holes, so it is more resistant to high pressure and high temperature.

 

3, The inside seals bellows are more longer than normal bellow seal globe valve, which is more corrosion resistant and have a longer service life.

4, bellow seal globe valves are lighter than normal globe valve in open and off.
