- 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 PPG 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.
- 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.

Thermoplastic Butterfly Valves 28"-48" 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. Valves
shall have epoxy coated gear actuators with handwheel. 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)
