1Precision small ordinary switch type electric cast steel ball valveIntroduction

Electric cast steel ball valve is a type of ball valve made of cast steel (such asWCB, CF8, etc. are valve body materials, which are driven by electric actuatorsA valve that drives the rotation of a sphere to achieve medium on/off or regulation. Its core component is a sphere with a circular channel,rotate90 ° can quickly open and close, suitable for industrial pipeline systems with high pressure, high temperature, or corrosive media.

IIPrecision small ordinary switch type electric cast steel ball valveworking principle

Switch control:

Electric actuators receive signals (such asDC24V、AC220V/380V）， Drive the sphere to rotate 90 degrees (fully open or fully closed).

Some actuators are equipped with position feedback (such as potentiometers, encoders), which can monitor valve opening in real time.

Flow regulation（V-shaped ball valve):

Sphere withV-shaped incision, achieving precise flow control by adjusting the opening (suitable for slurry and dust media).

IIIPrecision small ordinary electric cast steel ball valveThe main types

Classification method type feature

Spherical structure floating ball valve The sphere compresses the valve seat under medium pressure and is suitable for small diameters（≤DN200）

Fixed Ball Valve The sphere is fixed by bearings, with low torque, suitable for high pressure/Large caliber (≥ DN200)

runner design Full bore ball valve The flow channel is of the same diameter as the pipeline, with low pressure loss, suitable for transporting fluids

Reduced diameter ball valve The flow channel is smaller than the pipeline, with a compact structure and lower cost

Functional purpose Switch type ball valve Only for fully open use/Fully closed (such as O-type ball valve)

Adjustable ball valve Proportionally adjustable flow rate (such asV-shaped ball valve

connection method flanged High pressure, large-diameter pipelines（PN16~PN420）

threaded Small caliber（DN15~DN50）， easy installation

welded type High temperature and high pressure applications (such as oil pipelines)

4Precision small ordinary electric cast steel ball valvethe advantage of

Quick switch:Rotate 90 ° to complete opening and closing, with fast response speed.

Good sealing: soft seal（PTFE can achieve zero leakage, and the hard seal (metal) is resistant to high temperature and high pressure.

Low flow resistance: The full bore design has almost no pressure loss.

Long lifespan: Wear resistant, corrosion-resistant, suitable for harsh working conditions.

Automated control: can be remotely operated, supportsPLC/DCS integration.
