Plastic Control Valves Handle Corrosive Chemicals
Collins 2-in. valves and actuators are specially designed to handle corrosive fluids - acids,
bleaches, chlorine, pH control - and aggressive environments
C
ollins Instrument Company's line of
economical 2-in. flanged plastic control
valves handle corrosive liquids including
hydrochloric acid, caustic, sulfuric acid, and
many others. With bodies of either PVDF
or polypropylene, these highly-responsive
control valves are specifically designed for
use with corrosive media and/or corrosive
atmospheres.
Suitable for applications in numerous industries,
including chemical, petrochemical,
pulp and paper, and municipal, these valves
are extremely corrosion-resistant, and feature
fast-acting positioning (stroke rate
approximately 1⁄2 in./s). They are available
with a wide selection of trim sizes, in globe,
angle, and corner configurations.
The differential-area piston eliminates
the necessity for auxiliary loading regulators.
All actuator parts apart from the integral
positioner are molded of glass-filled,
UV-inhibited polypropylene. Before shipment,
the aluminum positioner and a portion
of the cylinder are immersed in Dip
Seal to provide atmospheric protection.
environments that can attack the outside
of the valve and actuator. Collins plastic
control valve packages withstand salty marine
atmospheres as well as industrial environments
that are too corrosive for metal
valves and actuators.
Plastic valves and actuators from Collins
The integral positioner eliminates the need
for external linkages which are subject to
corrosion and malfunctioning. Valves may
also be furnished without a positioner for
on/off applications.
Collins also offers a plastic pneumatic
actuator. The combination of a plastic actuator
and a plastic valve body provides an
effective way to handle both corrosive materials
flowing through the valve, and harsh
Valve Manufacturing Done Right
I
nline Industries, a California corporation, manufactures industrial
valve products for the U.S. and international marketplace. Inline
specializes in the production of high performance, corrosion resistant
ball valves and automated systems. Inline delivers exceptional
value to customers by providing the three most important elements
they look for in a manufacturer: quality, availability, and price.
In today's climate of competitive pricing, contract manufacturing
of components has become a way for many valve companies to
enter the market or to remain in the game. Unfortunately, quality
and delivery can often suffer as a result. Inline Industries manufactures
products in its own facilities, sustaining internal quality control
while maintaining extensive inventories. With Inline, clients are
free to focus on
plant operation,
rather than worrying
about equipment

Collins actuators incorporate a unique
internal locking ring to attach the cylinder
to the yoke. A semicircular groove is machined
inside the lower edge of the cylinder,
and a matching groove cut in the yoke.
When the yoke and cylinder are assembled,
a flexible polypropylene rod is inserted into
the groove through a slot in the side of the
cylinder, securing the two sections together.
Along with its corrosion resistance the
Collins control valve features a stem packing
arrangement that virtually eliminates
the problem of fugitive emissions, thereby
protecting the environment.
