Rising Stem Ball Valve

Rising Stem Ball Valve

Friction free opening and closing/Low maintenanceFriction free opening and closing. Excellent against frequent switching and dirty service (fines). No friction on the seal. Compared with other type of valves an exceptional long life time. Unique designed helix stemThe helix shaped stem design ensures absolutely no stem rotation Single seat designOptimal performance in high temperature service and services with continuously fluctuating temperatures and pressures (thermal expansion). No problems of trapped pressure between seals Metal to metal sealingSuitable for almost all temperatures. Fire safe design. Increased lifetime of the valve. Advantage

Helix stem ensures low maintenance due to non-contact, friction free opening and closing, which is excellent for frequent cycling.
Anti-blowout stem design
Backseat allows adjustable stem packing while valve is in service
Self-cleaning of sealing area due to immediate flow before rotation.
No rubbing/friction between sealing surfaces which is the primary cause of valve failure
Standard design with Outside Screw and Yoke for easy gland packing adjustment.
Top-entry design for in-line service or maintenance.
Heavy wall thickness according API 6D/API600 provides extra corrosion allowance to reduce wear and extend the valve lifetime
Extended lifetime due to the selection of high quality materials which help prevent against wear and corrosion. Corrosion and wear resistant materials (Stellite 6) are used as closure members (ball/seat)
Mechanically energized sealing.

No weak points to obtain sealing like: - springs, - soft seals, - coupling cam constructions with pins, lubricated seals.Options
