- Easier installation due to narrow face to face
affords lowest installed cost compared to other valve types
- Designed to fit between ANSI D-16.5 Class 150
flat faced flanges.
- Strong, one piece molded body design.
- One piece standard S.S. through shaft for positive
disc rotation and support.
- Standard polypropylene (PP) disc for higher
(180ŠF) temperature service.
- Full body liner seat with integral flanges (eliminates
the need for flange gaskets) ribbed for positive flange seating
with minimum required torque.
- Standard PVC body and S.S. shaft are effectively
isolated from the flow media by the full liner seat.
- Standard S.S., carbon steel plated, or epoxy
coated external hardware for added corrosion resistance.
- 2" - 8" valves have spring loaded
latch lever for positive disc positioning and shut-off.
- 8" - 8" valves have epoxy coated self-locking
worm gear actuators for ease of operation and accurate flow control.
- Electric and pneumatic actuation packages available.
- Locking handles available.
- Stem extensions, universal joints, floor stands
available in a variety of materials.

Testing performed on PVC/PP/EPDM valves at 73°F water temperature, non-shock.
Thermoplastic Butterfly Valves 2"-8" are wafer style to
fit between ANSI B16.5 Class 150 flanges. Disc is contoured for
lowest possible pressure drop ( highest Cv). Shaft is 410 S.S. and
of one piece, through shaft design, with square drive through entire
length of blade. 2" - 6" valves shall be complete with
a spring loaded 6 position latch lever. 8" valves shall be
either spring lever or gear actuated as required or specified. Seat
liners shall be full faced with integral, ribbed flanges. No auxiliary
gaskets shall be required for installation. Seat liners shall effectively
isolate the body and shaft from the flow media. Seat liners shall
also thermally insulate the body from the internal operating temperature.
Valve liner and seals are replaceable. Materials of construction
shall be: (select as required for service)
Note: The universal style 2-4" butterfly valve fits between
ANSI B16.5, DIN, and JIS class 150 flanges, the 6" between
ANSI and JIS flanges and the 8" between ANSI flanges.
