- Lower initial cost compared to other valve
types.
- Easier installation due to narrow face to
face affords lowest installed cost.
- 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
(180°F) 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.
- Electric and pneumatic actuation packages
available.

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 smooth and
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 minimum 11 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 used
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)
