8 Thecam-like action produced by the offset stem and disc,effectively lifts the disc off the seat during the initialopening of the valve, reducing seat wear and eliminatingseat deformation at the top and bottom. When the disc isin the open position, there is no contact between the discand seat. Operating torques are reduced and seat life drop tight sealing capabilities of MAX-SEAL valvesare excellent for vacuum service. Soft seated standardvalves are suitable for vacuum service to 20 vacuum service on the standard Valves are ideally suited forsaturated steam applications to 120 psig steam (RPTFE seat).
