- Manufacturer:
Emerson
- Valve Type:
Isolation
- Sub-Type:

- Cast double flanged butterfly valve, which can be drilled acc. various flange standards (JIS, BS, ISO/EN, ASME and AWWA). Dead-end service capability with down stream piping removed.
- Body and disc protective coatings or rubber linings are available for sea water or corrosive services.
- Low headloss thru optimized disc design.
- The special seat and disc edge contours reduce seating torque, provide better shut-off and longer service life.
- The seat is adjustable in order to optimize the required shut-off tightness with the accompanying torque, for unidirectional or bidirectional operation.
- Replaceable seat without special tooling, dismantling or removing the valve from the line.
- A stainless steel disc edge resists against corrosion and avoids encrust build-up for consistent sealing.
- Dry shaft design.
- High strength stub shafts have full 1½ diameter penetration into disc-hubs with close tolerance-fit.
- Self lubricating sleeve bearings allow valve installation with the shaft horizontal or vertical.
