BUTTERFLY VALVES
RESILIENT SEATED BUTTERFLY VALVE
valves are designed to meet the rigorous
requirements of industrial applications such
and utilities, chemical/petrochemical, food
and beverage, OEM and HVAC. Each
valve is manufactured in accordance with
100% tested in both directions of operation to
assure bubble-tight service for many years.
Features:
•
• Standard aluminum-bronze disc
• Mounting pad with square shaft permits
direct mount actuation that reduces
hysteresis and cost (2" TO 12")
• Secured stem retainer plate for blowout-
proof protection and also allows operator
removal with valve in line
• High strength two-piece stem eliminates
• Rated to 200 PSI (2"-12"), 150 PSI
(14"- 24")
• Cartridge style seat permits easy change
without special tools
• Molded o-ring eliminates the need for
Lockable Handles (up to 8")
•
• Shell tested to 150% and seat tested to
• Lug bodies for dead-end service rated at
150 PSI** (2"-12"), 100 PSI** (14"-24")
• Dual PTFE shaft bearings for reduced
torque and improved stem alignment
• Vacuum rated to 29.9196"Hg (0.01 Torr)†
• Epoxy coated body
• Low maintenance design
Standards:
• NSF 61 Annex G Certified
(Annex G references NSF 372)
• Design: API 609A and MSS SP-67
•
MSS SP-61
• Top Flange to: ISO 5211
Options:
for valves. These include, but are not
limited to: Actuation including chain wheels,
square drive nuts, worm-gear operators, and
pneumatic and electric operators, control
accessories, stem extensions, and custom
mounting hardware. Contact FNW with your

* Pressed collar style angle face rings (typically sizes 2" to 6") are not recommended due to the large radius
of the inner diameter. Cast type angle face rings or stub ends should be used with light wall stainless steel
piping. Prior to installation, always verify that the connecting piping flange face fully engages the valve
seat face.
† Vacuum measurements are often made in inches of mercury below atmospheric pressure. The values
calculated here assume standard atmospheric pressure of 29.92 inches of mercury.
