一．Product Introduction
Q941F type PN16~PN63 floating soft-sealed electric ball valve: electric drive, flange connection form, floating ball straight-through type, the sealing form adopts soft seal, the seat sealing surface material is fluorine plastic, the nominal pressure is PN16~PN63, the nominal size is DN15~DN200, the applicable temperature is -28~300℃, the valve body material is carbon steel or stainless steel.
Q941F type PN16~PN63 floating soft seal electric ball valve is suitable for two-position cutting and adjustment occasions.The connection between the valve and the actuator adopts a direct connection method, which consists of DCL series precision small electric actuators (different types of electronic electric actuators or gas piston actuators can also be configured according to user requirements) and ultra-short ball valves.The electric actuator has a built-in servo system, no need to be equipped with a servo amplifier, and the operation can be controlled by entering a 4-20mA signal and a 220V AC power supply.Compared with ordinary electric ball valves, it has the characteristics of compact structure, small size, light weight, close distance between the valve seat and the end flange, less material retention, and superior sealing performance.
二.Product Features
– Our pneumatic lined fluorine ball valves are specifically designed to provide exceptional corrosion resistance and reliable performance in demanding industrial applications.
– These valves are constructed with a fluorine – lined interior, which offers excellent resistance to a wide range of aggressive chemicals and corrosive media.
– The fluorine lining acts as a protective barrier, preventing direct contact between the media and the valve body, ensuring long – lasting durability and minimizing the risk of corrosion.
– This makes our pneumatic lined fluorine ball valves ideal for applications in industries such as chemical processing, petrochemical, pharmaceutical, and water treatment.
