 Applied in high- temperature dry-gas hydrogen production, atmospheric-vacuum distillation/catalytic devices. It requires fast and safe cut off, quick open. Double solenoid valve ensure control,  tight-close, frequent-operation. Open and close every ten minutes at high temperature. The AQH ball valve adopts the plate spring loading seat structure, which is suitable for the high temperature working condition; the sealing surface sprays the cemented carbide, the mechanical grinding can realize the ANSI VI class seal, the valve seat adopts the extruded graphite seal ring, to guarantee the floating state of sealing mechanism. And it has got API6H fireproof certificate.
