Q941 floating ball valve

Q941 floating ball valve

Type Q941Y PN16 ~ PN63 floating hard seal electric ball valves, electric drive, flange connection, the floating ball straight through, seal form is hard seal, valve seat sealing surface materials for carbide, PN16 ~ PN63 nominal pressure, nominal size DN15 ~ DN200, suitable temperature for - 28 ~ 500 ℃, the valve body material is carbon steel or stainless steel. Because of using hard seal (metal seal), especially for this valve granularity, solid plant-based, pulp and other medium and high temperature and high pressure pipeline. 
Type Q941Y PN16 ~ PN63 floating hard seal electric ball valve is suitable for both cutting and adjusting the occasion. Valve and actuator connection adopts direct method, by the DCL series fine small electric actuator (also can according to user requirements with different type electronic type electric actuators or pneumatic piston actuator) and ultra short of ball valve. Electric actuators are built-in servo system, do not need to match servo amplifier, 4-20 ma signal input and 220 v AC power supply can control operation. Compared with ordinary electric ball valve has a compact structure, small volume, light weight, seat and end face of the flange is close, less material stranded, sealed performance is superior, etc.
