FEATURE | FUNCTION | BENEFIT |
|---|
Molded-in resilient seat | Provides bubble-tight shut off to 150 psi | Reduces energy costs associated with media leakage |
Lugged body | Drilled and tapped two-sided connection | Allows isolation and removal of downstream piping while system is pressurized |
Round polished disc | Provides 360° concentric seating, minimum flow restriction, lower torque requirement, and longer seat life | Enables superior close off, while decreasing energy losses Lower torque requirements allow use of lower cost actuators Provides years of trouble-free service |
Upper and lower inboard bronze bearings | Precisely aligns disk and reduces friction | Requires lower torque and maintains precise alignment for positive close off |
Thru-stem design | High strength and positive disk control, as well as standardized end connection | Increases control and allows for various actuator configurations |
Extended neck | Provides additional clearance | Allows full insulation of piping and maintains clearance for flanges |
Heavy duty corrosion resistant top bushing | Supports stem against side loads | Superior control and long life |
