Resilient Seat Butterfly Valves

Overview

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
