• the stem blow-out design is safe and reliable, fully meet the requirements of API 609.
• composite metal sealing ring elastic characteristics of the valve with zero leakage performance.
• STEM upper position indicator and top mounting flange for disc position indication.
• The friction-free design of right-angle rotation is realized through a unique tri-eccentricity principle, which eliminates friction between the seat and the seal ring during 90 ° switch rotation.
• Optional Operation Mode. Turbine, electric or pneumatic devices may be used if required.
