Usage: Z41X-10Q/16Q/25Q uses the micro deformation and compensation effect produced by the elastic
gate when it is stressed to achieve good sealing effect. When in use, the medium temperature is not higher
than 80 ° C. It can be widely used in construction, food, chemical energy, water supply and drainage and
other industries. It can be used for regulation and closure of pipelines and equipment.
Application: chemitry industry, oil and gas industry etc.
