Detail Information

Flange retractable butterfly valve can compensate thermal expansion and contraction on pipe lines automatically. It is easy for assemble and disassemble. Flange retractable butterfly valve is widely used for pipe line to regulate or cut off medium in petroleum, chemical, electricity, etc.

Working temperature: ≤425℃

Nominal pressure PN: ≤1.6MPa

Characteristics:

1. Unique structure, light weight

2. Flange retractable butterfly vale can compensate thermal expansion and contraction on pipe lines automatically and convenient for usage.

3. Sealing parts can be changed, having reliable sealing.

Notes:

1. The valve must be laid before installation. Holder is not allowed to remove during transporting.

2. The structure length of flange retractable butterfly valve is minimum length in the factory. It should be pulled to installing length (design length).

3. When length between pipes is larger than design length, adjust the length. It is not allowed to force the valve in case of damage.

4. The valve can be installed in any position. When using for compensating temperature, two ends of pipe need to add holder to avoid extension tube pulling out.
