Wafer and lugged body design with face-to-face dimension, according to EN 558 Series 20 and API 609.
Designed according to EN 593 and API 609.
The seat is field replaceable and fully isolates the body and shaft from the flow.
Primary shaft 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.
Shaft seals prevent moisture penetrating into the shaft area.
The two piece shaft allows for a thin disc and provides minimal obstruction to flow (up to DN 300/ NPS 12).
Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and drop-tight shut-off.
Body locating holes allow ease of installation and centering between the flanges.
Extended body neck allows for pipe insulation.
Top and bottom shaft bearings for optimized support and minimum friction and decreased torque.
