General Service Butterfly Valve, ANSI Class 125 Lugged, 200 PSI CWP, Cast Iron (ASTM A-126-B) Body, EPDM Seat (-30 to 275°F), Aluminum Bronze (ASTM A-148) Disc, 416 stainless steel (ASTM A-582) Shaft, 10-Position Lever.
Service Recommendation
Soft seated butterfly valves are designed for general applications such as
on-off, throttling and isolation in residential, commercial and industrial
piping systems.
They are well suited for control of water, steam, air, oil and gases. The
seat design is especially well suited for vacuum service to 28" Hg and
high velocity service.
Features
The seat is made of a highly wear resistant elastomer with a phenolic backup
ring. This combination provides a soft, elastic seat which will not collapse
under vacuum or high velocity service and eliminates the need for flange gaskets.
The stem seals consist of a primary seal between the spherical disc hub and
the spherical seat hub. The secondary seals are O-rings at the top and bottom
of the stem to retain lubrication and prevent atmospheric corrosion. The stem
is blowout proof.
These valves are furnished with ten position handles.
ISO mount on 2-36". Double D shaft on 2-8".
Body Pressure-Temperature Ratings In accordance with ANSI B16.1 (Cast Iron)
except as limited by the elastomer seats.
