The
LOCXEND Model 59G butterfly valve offers economical,
efficient, and reliable service for grooved end
piping applications. It is easily installed with
two grooved end couplings. LOCXEND butterfly valves
are ideally suited for use in mechanical rooms,
process lines, condenser water lines, demineralized
water lines, and chilled and hot water lines.
The rugged ductile iron body is epoxy coated on
all wetted surfaces and all surfaces exposed to
the atmosphere. This provides both internal and
external corrosion protection.
The EPDM encapsulation on the disc provides protection
from chemical attack and erosion and also forms
a bubble tight seal against the inside wall of
the valve. O-rings in EPDM prevent atmospheric
corrosion to internal parts.
The top flange is symmetric to accept many different
manual or gear operators as well as electric,
pneumatic, and hydraulic actuators. The extended
neck allows ample room for insulation.
The EPDM encapsulated disc is designed to minimize
turbulence and maximize good flow characteristics
as well as provide positive sealing, protection
against erosion and corrosion, and low sealing
torque. The service temperature for EPDM is -20
degrees F (-29 degrees C) to 220 degrees F (104
degres C). |
