Floating Type Ball Valve

The Floating Type Ball Valve employs a floating ball structure. Under the pressure of the medium, the valve ball presses against the downstream valve seat to form a seal. Rapid opening and closing is achieved through 90° rotation, making it suitable for industrial pipeline shut-off.

Floating Ball Structure: The valve ball has no fixed upper or lower support. Under upstream pressure, it moves downstream to the valve seat, increasing the sealing contact force and achieving stable shut-off.

Anti-Blowout Stem: An anti-blowout structure is used to limit the axial displacement of the valve stem, improving operational safety under high-pressure conditions.

Valve Seat Seal: PTFE, RPTFE, PEEK, and other valve seat options are available, selectable based on the medium, pressure, and temperature.

Automation Interface: Configurable ISO 5211 mounting interface for direct installation of pneumatic or electric actuators.

Valve Body Material: Common materials such as WCB, LCB, CF8, CF8M, and CF3M are available. Alloy materials can be selected for low-temperature, corrosive, and special media.

Valve Seat Material: PTFE and RPTFE are suitable for general operating conditions; PEEK is suitable for higher temperatures and pressures; metal valve seats can be evaluated for special operating conditions.

Connection Methods: Supports RF, RTJ, NPT, BSP, Socket Weld, and Butt Weld.

Actuation Method: Supports handle, worm gear, pneumatic, and electric operation.
