Floating Ball Valve

Floating Ball Valve

Full bore or reduced bore design

Floating ball

Prevent the valve stem from being blown out

The valve body is cast or forged

Fire protection standard API607/API6FA

Anti-static standard BS5351

Automatic pressure relief structure for the valve cavity

A locking device can be selected

Applicable temperature range: Soft seal: -46℃ to 200℃, hard seal: up to 425℃.

Characteristics

The locking device of the valve assembly's overall structure is used to fix the flow direction and restrict unauthorized operation

2. The bottom of the valve stem is designed in a T-shaped structure and is integrated with the protrusions on the valve body to ensure that the valve stem is not blown out by pressure

3. After being damaged by fire, non-metallic sealing materials can achieve metal-to-metal sealing to cut off the fluid flow of the valve

4. ISO5211 connection dimensions, adopting international standard connection dimensions, simplify the installation and execution structure

5. The design of the D-type valve stem head ensures the correct installation of the handle. The handle is always consistent with the flow direction and indicates the switch position

6. Low-leakage graphite gaskets are adopted to prevent leakage
