Q641F Pneumatic High-Platform Ball Valve

The pneumatic high-platform fire-safe ball valve features excellent sealing performance, high flow coefficient, low flow resistance, a simple structure, and a long service life. The pneumatic actuator is housed in a highly corrosion-resistant casing, with a visible position indicator and a compact, maintenance-free design.

The actuator's mechanical friction is maintained between Ra 0.4–0.6, minimizing wear and ensuring maximum lifespan.

Smooth components reduce friction, preventing metal-to-metal contact and extending operational durability.

Each actuator undergoes 100% rotation and sealing tests before leaving the factory, guaranteeing a service life of over 1 million cycles.

Valve Features

Precision investment casting ensures high-quality construction.

Fire-safe design meets stringent safety standards.

Unique high-platform structure simplifies actuator installation.

Anti-static device between the valve stem and body prevents electrostatic discharge.

Blowout-proof stem enhances safety under high pressure.

Pressure balance hole on the steel ball ensures stable operation.

Double-layer stem packing and dual-disc spring washers ensure reliable sealing.

Stem leakage complies with German TUV TA-LUFT standards.

Self-cleaning valve cavity design prevents contamination buildup.

This valve is ideal for applications requiring high reliability, fire safety, and long-term performance in demanding industrial environments.
