Tonglu Yongxin Valve Co.,Ltd. was founded in 1994, is one of the largest manufacturers in the production of valve,from Tonglu,China. Since 20 years' hard work, probity, and innovation "attention to detail, careful to do everything, has continued to move" to build the first national manufacturer of valve "and make unremitting efforts. Due to our scientific management and Seiko secret agents, as well as "to all customers, all services to the customer" philosophy respected, got the trust of new and old customers.
XUVAL centric butterfly valves with fixed liner feature an outstanding seating concept. The rubber is injection molded directly on the valve body forming a permanent bond. Consequently, there is no risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The combination of the profiled disc edge and the excellent XUVAL rubber quality ensures maximum durability of the liner.
