Cast Steel Floating Ball Valve
Taian isCast Steel Floating Ball Valve professional manufacturer,we will offer you the best after-sale service and timely delivery.The valve body is made of cast carbon steel, alloy steel or stainless steel (such as A216 WCB, A351 CF8M, A352 LCB, etc.), formed by one-time casting, suitable for mass production and with relatively low cost. Cast Steel Floating Ball Valve is in a "floating" state within the valve cavity, without fixed bearings, and is positioned only by the valve stem. The pressure of the pipeline medium pushes the ball towards the valve seat at the outlet end, forming a seal. The valve body type is available in two-piece or three-piece bolt connection, which is convenient for online maintenance. Full bore or reduced bore design is available.
Specifications
You can rest assured to buy Taian Cast Steel Floating Ball Valve from our factory.This ball valve is designed with a T-shaped structure at the lower end of the Blow-out Proof Stem. Restricted by the valve body protrusions, it prevents the valve stem from being pushed out by the medium pressure. The spring-loaded plunger of Cast Steel Floating Ball Valve maintains electrical continuity among the ball, rod and valve body, preventing static electricity accumulation.Fire Safety design is Compliant with API 607 / API 6FA; After the soft seal is burned out, the ball adheres to the metal valve seat to form a secondary seal. The ISO 5211 actuator installation platform can directly install electric, pneumatic or gear actuators. The handle is equipped with a padlock hole to prevent misoperation. Advantages such as optional gearbox operation for 6" and above.

Selection tips
Temperature & Medium: Below -20 °C, low-temperature steel LCB/LCC should be selected. For strong corrosive media, choose CF8M/F51. For high temperature and high pressure, consider WC6/WC9 or C5/C12.
End connection: BW butt welding is preferred when the pressure is high or the pipeline load is large. Flange ends are used in situations where frequent disassembly and assembly are required.
Fire protection requirements: Petrochemical plants, tank farms and docks must select API 607 Fire-Safe certified models.
Execution mode: For DN50 and below, a handle can be used. For DN65 and above, gearboxes or electric/pneumatic actuators are recommended.
