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.
