Vridspjällventil 731P,732P Wafer (Butterfly Valve 731P,732P Wafer)
A wafer or lugged pattern, rubber seated butterfly valve. The seat is vulcanised to the valve body, and incorporates a modified cosine curve seat profile. This provides lower torque, reduced friction and improved flow characteristics, especially at the partially open position.
The vulcanised seat also ensures improved performance under high velocity and vacuum conditions.
