Specifications

Metal Bellow Mechanical Seal ,valve bellows 
Material:AISI304,AISI316 etc. 

Metal Bellow Mechanical Seal , Metal Bellows Seal ,  Valve bellow

One unique feature of our bellows is the multi-layer and high pressure resistance that we use in the valve seal. The bellows are made of multi-layers of stainless steel, and the maximum could be seven layers which provide high flexibility and longer cycle life for the bellows and bellows assembly  The bellows assembly  are mainly used on shutoff valve , gate valve and regulating valve and the typical type of bellows assembly

Characteristic :

 

1. Application Range

The products could be used on bellows-type cut off valve, bellows-type gate valve and bellows-type regulating valve.

 

2. Nominal Diameter of Valve ( mm )

DN15~DN250

 

3. Nominal Pressure Class ( MPa )

PN1.6,  PN2.5,  PN4.0,  PN6.4,  PN10.0,  PN14.0

The bellows are designed to withstand external pressure, and the design pressure class is one and a half times of that of nominal pressure class.

 

4. Operation Temperature

-196 °C ~300 °C

 

5.Movement

The design movement ( compression ) is larger than the minimum movement while turning on the valve .

 

6.Cycle Life

The cycle life is over 10000 cycles under nominal pressure and movement.

 

7.Material

SS304, SS316L

We could design and produce the bellows and bellows assemblies with flanges according to the requirement from the customers.
