ASTM A216 WCB pneumatic ball valve is a specialized active control valve designed for explosion-proof and high-frequency operation pipeline systems. Its core features include "pneumatic actuator drive + ball rotation for flow cutoff + multi-material compatibility (stainless steel/cast steel) + explosion-proof structure." It is certified to industrial standards such as ISO 9001, CE, ASME B16.34, and ATEX (explosion-proof certification).
The standard temperature range is -40°C to 450°C (high-temperature models), with pressure ratings from Class 150 to Class 2500 (1.6–42.0 MPa) and nominal sizes from DN15 to DN300. The sealing class meets ANSI Class V to VI, making it suitable for applications involving liquids, gases, steam, and flammable/explosive media.
Widely used in industries such as petroleum refining (explosion-proof pipelines), chemical reactor control systems, natural gas transmission, and pharmaceutical cleanroom production lines, it addresses safety hazards of electric ball valves in flammable/explosive environments. With its "explosion-proof safety + rapid on/off + high-frequency operation compatibility," it serves as a core control component in explosion-proof and high-frequency operation pipeline systems.
