Regulating electric ball valve Electric regulating ball valve
Alternative name: electric regulating ball valve electric V-type regulating ball valve electric V-type regulating ball valve
Model: TFHDQ-0025V-0050
Overview of adjustable electric ball valve:
The regulating electric ball valve adopts V-shaped ball valve structure as the opening and closing parts, and its closing parts are V-shaped openings on the hemisphere, The V-shaped opening has a sharp edge. During the rotation of the ball, the closing parts have a wiping effect and a strong cutting force on the medium. The V-shaped opening of the ball and the valve seat channel form a sector area. During the rotation, the cross-sectional area of the channel can be changed to form an accurate adjustment of the medium. It is an angular rotation regulating valve with the same sealing performance as ordinary ball valves, It has two functions of regulating and switching at the same time. It is matched with pneumatic or electric actuators and is widely used in industrial process automation systems.

Model selection of adjustable electric ball valve:
The valve seat can choose metal hard seal or PTFE soft seal according to the needs of the medium and working conditions: the sealing surface of the metal hard seal valve seat is welded with hard alloy, the spherical surface is plated with hard chromium, or hardened by spray welding, ion nitriding, etc., so that the service life of the sealing surface is enhanced and the temperature resistance is improved; Soft sealing PTFE valve seat or enhanced PTFE valve seat has good sealing performance, corrosion resistance and wide application range.
