Electric telescopic butterfly valve Overview:

Electric telescopic butterfly valve is mainly composed of electric actuator and flange telescopic butterfly valve, the so-called telescopic butterfly valve is on the basis of the original butterfly valve, equipped with a telescopic valve of the same caliber as the butterfly valve. The structural characteristics of the electric butterfly valve not only bring convenience to the disassembly of the valve, but also alleviate the pipeline stress, and solve the internal force caused by the temperature difference, and compensate the thermal expansion and contraction caused by the temperature difference of the pipeline. The electric flanged butterfly valve can be installed at any position, mainly used to control the switch cut-off control of pipeline media, and can also be used to adjust the flow.

Electric telescopic butterfly valve design standards:

Design standard: GB/T12238-1989; JB/T8527-1997

Flange connection size:

GB/T9113.1-2000; GB/T9113.2-2000;

GB/T9115.1-2000; GB/T9115.2-2000

Structure length: GB/T12221-1989

Pressure test: GB/T13927-1992; JB/T9092-1999

1. Used on the pipeline, it can produce axial displacement (elongation, compression).

2. Used in the pipeline, it can reduce vibration and reduce the transmission noise of the structure.

3. The valve is used in the pipeline, within the specified scope, not subject to pipeline restrictions.

4. Unlimited flange parallel restrictions, can be installed arbitrarily, light weight, good elasticity.

Electric telescopic butterfly valve structure advantages:

The structural length of the electric flange expansion butterfly valve can be adjusted in a certain range when the valve is installed, which can also relieve the pipeline stress and protect the valve. And the installation is not affected by the medium and flow direction, but also concentrated the installation method of the butterfly valve and the expansion device, and the space is more compact. Under normal circumstances, the electric telescopic butterfly valve does not need special maintenance, and only needs to periodically observe whether there is leakage and pulling out of its telescopic part.

Electric telescopic butterfly valve application:

Electric telescopic butterfly valve can be divided into ordinary type, fixed limit type, extended type, suitable for temperature ≤80℃, pressure ≤1.6MPa working conditions, and the use of flange connection. Generally used in electric power, metallurgy, petroleum, chemical, gas and solid powder pipeline for adjustment and cut off use, with compensation pipe thermal expansion cold contraction function.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
