Manual or automatic
Automatic sealing
Eccentric or bi-excentric disc
Flanged Type for Flanges Installation According to ASME, Awwa, DIN and NBR standards. Face-to-Standard Faced Awwa C-504.
Rod sealing
Disc designed to provide low load loss in fully open position, as well as allowing greater flow of fluid in small disc spray angles.
Manual or automatic
Sealing by means of gaxetas with premeated gasket mounted in the inverted position,
allowing easy adjustment and uniform compression of gaskets, and does not
interfere with actuator assembly directly on the top -top flange. Standardized gaskets, facilitating their interchange.
Automatic sealing
It allows the coupling of manual, pneumatic and electrical drives directly on the top flange that, in conjunction with the rod, follows ISO 5211.
Site
Mechanically nailed to the body with polished sealing surface, ensuring low drive torque and longer life to seal.
Finite elements
Project developed with the aid of software for analysis of finite elements ensuring greater structural reliability to the set.
