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
