Well-designed Lever Handle Ball Valve - Triple eccentric butterfly valve with pneuamtic actuator – GMK Valve Detail:
The triple-eccentric hard seal butterfly valve adopts the design of triple-eccentric structure. There is no friction between the disc and seat within the full travel range of disc opening and closing, so that the leakage caused due to seat abrasion during seat opening and closing in rotary control valves is eliminated. The seat adopts the multi-level structure and uses the combination of metal and nonmetal materials to form the sealing face. It can work excellently under the service conditions of high and low temperatures. The 70D00 Series butterfly valve is featured by long service life and excellent sealing performance. It is suitable for control and shut-off applications of almost all gases and liquids in the industrial process control.
