The Ultraflo series of butterfly valves is designed to meet the highest quality standards where less than a perfect fit is unacceptable. The design features of our products are the result of years of actual operating characteristics of our products as well as our competitors.
A Stainless Stem
17-4 PH stainless stem is high strength for positive disc control and allows for full range product service.
Butterfly Valve
B Top Plate
CNC machining and standardized drilling allow total actuator or manual handle interchangeability.
C Stem Bushing
Heavy duty corrosion-resistant top and bottom ertalyte stem bushings absorb operator side thrust. Precision alignment of top and bottom bushings insure reliable, trouble-free valve operation and lower operating torque.
D Stem Packing
Buna-N self-adjusting secondary stem seal insures positive seal for pressure or vacuum service.
I Disc
CNC machined for positive seal. Contoured edges and rounded hub edge are hand-polished for lower operating torque and increased seat life. Disc is constructed for maximum product flow.
E Seat Retention
Dove-tail seat retention method seals housing to seat and simplifies seat replacement.
J Flange Seal
Sealing section of resilient seat provides positive seal to all popular flanges.
F Product Seal
Formed by disc hub in contact with flat surface of special resilient seat and from interference fit between stem and seat hole.
K Lower Stem Bushing
Unique ertalyte lower stem bushing eliminates galling and frozen stems.
G Resilient Seat
Easily replaceable seat protects housing and stem from product contact. Seat is available in several compounds to meet practically any application.
L Seat
Double O-Ring for positive stem seal.
H Housing
Notched body for mounting between light-weight flanges. Wafer and lugged designed for 125/150 ANSI. All iron bodied valves powder epoxy coated.
M Baked Epoxy Coating
