KSB

Product benefits

Long gland life and high functional reliability

• Stem with shank burnished to a surface finish of 0.2 μm for reduced friction, lower actuating torque and improved sealing to atmosphere.
• Packing end rings enable higher compressive force by gland follower and prevent extrusion of middle graphite packing rings.

Product benefits

• Reliable sealing: bonnet gasket fully confined to prevent creep.
• Improved energy efficiency of the system. Short, easy-toinsulate bonnet minimises heat losses.
• Additional stem seal for emergency operation and blowout protection by standard back seat as well as back-up gland packing made of pure graphite.

Product benefits

• High operating comfort at no extra charge due to position indicator with travel stop and locking device outside the insulation. Valve disc position can be checked at any time.
