Principais características

Top bushing absorbs actuator side thrust loads.
Dirtscraper prevents moisture penetrating into the shaft area.
Actuator flange acc. ISO 5211.
High solid, glossy, silicone free, paint system ensuring excellent corrosion resistance.
Body locating holes ease installation and centering between the flanges.
Sealed body splits prevent moistures from penetrating behind the seat (up to DN 300).
Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and bubble-tight shut-off.
The seat is field replaceable and fully isolates the body and stem from the flow.
Primary stem sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere.
A secondary shaft sealing provides back-up safety.
A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets.
The thin disc provides the very minimum obstruction to flow (up to DN 300).
