Ball valve of liquid ammonia crane arm The ball valve of the loading arm of the liquid ammonia crane pipe adopts a two-piece valve body, and the valve rod is designed with a bottom mounted structure of reverse sealing. When the valve chamber is abnormally pressurized, the valve rod position will not leak or the valve rod will not be flushed out when the switch acts Consult immediately View details -
Welded ball valve of liquid ammonia loading arm The liquid ammonia loading arm welded ball valve and the liquid ammonia crane pipe butt welded ball valve are equipped with springs between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate stably and flexibly for a long time Consult immediately View details -
