Flanged Ball Valve Introduction
A flanged ball valve is a type of ball valve with flanged connections, featuring a spherical disc (ball) with a through-hole that rotates 90° to control fluid flow. Known for its simple structure, reliable sealing, and easy operation, it is widely used in industrial piping systems such as oil & gas, chemical, power, and water treatment.
Body: Typically made of carbon steel (CS), stainless steel (SS), or other materials to withstand pipeline pressure.
Ball: A rotating sphere with a bore; hardened or coated for wear resistance.
Seat: Usually PTFE or metal for tight shut-off.
Stem: Connects the actuator (handle, gear, pneumatic/electric) to the ball, transmitting torque.
Flange: Standardized (ANSI, DIN, JIS) for bolted pipeline connection.
Open: Ball bore aligns with the pipeline, allowing flow.
Closed: Ball rotates 90°, blocking flow.
Flow Control: Partial rotation adjusts flow rate (available in certain models).
Excellent Sealing: Soft seats (PTFE) achieve bubble-tight shut-off; metal seats suit high temp/pressure.
Low Flow Resistance: Full-bore design minimizes pressure drop.
Quick Operation: 90° on-off, ideal for automation (with pneumatic/electric actuators).
Easy Maintenance: Modular design; some models allow in-line repair.
Wide Compatibility: Handles water, oil, gas, and corrosive media (material-dependent).
