Design Feature:
·Anti-blowout stem for high dependability, completely conforming to API 609.
·Elastic property of composite metal sealing ring to perform zero leakage. 
·The valve position indicator on the stem and the flange mounted at the top are in favor of the indication of disc position. 
·The design of right-angled rotation with zero friction is implemented by the distinctive triple eccentric principle. It eliminates the frictionbetween the seat and sealing ring in 90°rotation.
