Selection of bottom valve options for crystallization processes

Thread Content

During the production processes in industries such as chemicals, pharmaceuticals, food, and biology, the medium at the bottom of the tank tends to crystallize at the valves. This causes the valve stem and seat to be surrounded by these crystals, which form into solid masses. As a result, the valves become difficult to operate – they may not close properly or fail to open at all, thereby severely affecting their proper functioning. To address the crystallization issue in bottom valve, traditional solutions typically involve insulating the outer layer of the valve, using heating media, or even poking it with a stick; alternatively, operations are halted to remove the valve for cleaning and maintenance. As a result, valves need to be replaced frequently and fail quickly, which severely impacts production, reduces the efficiency of enterprises, and even poses safety hazards. For bottom valves used in processes involving crystallization, a new type of valve can be chosen – an ice-breaking bottom valve that completely solves the problems posed by crystallizations freezing and sticking to the valve, as well as by gravitational friction. This helps to extend the service life of the bottom valve, improves production efficiency, and reduces costs.
