TDT1 series triple-eccentric multilevel hard sealing butterfly valve

TDT1 series triple-eccentric multilevel hard sealing butterfly valve applies the design of triple-eccentric structure. So, there is no friction with valve seat, while plate is open and close fully. It eliminates the leakage from seat abrasion caused by open-close operations of rotatory controlling valve. The valve seat applies multilevel construction, and a sealing face is formed by bonding metallic and non-metallic materials. This type of butterfly valve has long lifetime, excellent sealing performance, and good behaving under both high and low temperature conditions.
