What is Electric three-piece ball valve?

Electric three-piece ball valve is a widely used electric valve this year, has its own superiority,the  frictionless switch, seal will not be worn, small opening and closing torque, optional actuators to achieve the cut-off or regulation of the medium mainly precision small.

Nowadays, it is the preferred product for gas equipment, petrochemical, aerospace, vacuum equipment, electroplating equipment, agricultural machinery, food machinery, iron and steel metallurgy, HVAC, drying equipment, biopharmaceutical, medical equipment, and other industries.

The imported electric three-piece ball valve can be selected according to the connection method of threaded connection, butt welding connection, and flange connection.

The valve body casting adopts the technology with reasonable structure and a beautiful shape. The valve seat adopts an elastic sealing structure, reliable sealing, and easy opening and closing. The valve stem adopts an inverted seal under the installation structure, the stem will not be flushed out when the valve cavity is abnormally pressurized.

Two-piece and three-piece ball valves are available in butt weld (BW) and socket weld (SW) connections, and can be equipped with an international standard ISO bracket platform and locking device. It can be set 90 ° switch positioning mechanism, according to the need to add a lock to prevent operating errors.

Imported electric three-piece ball valve installation

1、Remove the protective cover on both sides of the flange end and flush clean with the valve fully open.

2、The whole machine should be tested according to the specified signal (electric or gas) before installation (to prevent vibration due to transportation from affecting the use of performance), and only after passing the installation.

3、Before preparing to connect with the pipeline, it shall be flushed and cleared of residual impurities in the pipeline (these substances may damage the valve seat and ball).

4、During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.

5、Ball valves should be installed in the horizontal or vertical direction of the pipeline.

6、The pipeline near the installation point must not have low hanging or bear external force, you can use pipe support or support to eliminate the deviation of the pipeline.

7、After connecting with the pipeline, please cross-lock the flange connecting bolts with the specified torque.

Electric three-way female threaded ball valve product advantages

1、Small fluid resistance, its resistance coefficient is equal to the same length of the pipe section.

2. Simple structure, small volume, lightweight.

3. Tight and reliable, the sealing surface material of the ball valve is widely used plastic, good sealing, and has been widely used in vacuum systems.

4. easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 °, and easy to control from a distance.

5. easy to maintain, the ball valve structure is simple, the seal is generally movable, and disassembly and replacement are relatively easy.

6. In the fully open or fully closed, the ball and seat sealing surface and media isolation, the media through, will not cause erosion of the valve sealing surface.

7. Wide range of applications, diameters from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
