3IN DUCTILE IRON KEYSTONE BUTTERFLY VLVE
- Item Code: GRW-48
- Unit Size: 1
Description
3 inch Keystone Series GRW Butterfly Valves heavy duty industrial resilient seated Wafer body design
Features
Back To Top- A molded-in O-ring in the seat for flange sealing eliminates the need for gaskets
- Designed according to EN 593 and API 609
- Extended body neck allows for pipe insulation
- The seat is field replaceable and fully isolates the body and shaft from the flow
- Top and bottom shaft bearings for optimized support and minimum friction and decreased torque
- Wafer body design with face-to-face dimension, according to EN 558 Series 20 and API 609
- A secondary shaft sealing provides back-up safety
- Body locating holes allow ease of installation and centering between the flanges
- Primary shaft sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere
- Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and drop-tight shut-off
- 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)
