Item | Specifications |
Application Range | The products could be used on bellows-type cut off valve, bellows-type gate valve and bellows-type regulating valve. |
Nominal Diameter Of Valve (mm) | DN15 - DN250 |
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. |
Operation Temperature | -196ºC - 300ºC |
Movement | The design movement ( compression ) is larger than the minimum movement while turning on the valve. |
Cycle life | The cycle life is over 5000 cycles under nominal pressure and movement. |
Material | SS304, SS316L, SS321 |
