True Union 3-Way
True Union Flanged
The True Union feature, a Chemtrol introduction, an exclusive Chemtrol
introduction, so revolutionized the industrial plastic valve industry that it
has become the standard followed by all major manufacturers. The purpose
of the design is to permit the valve cartridge, i.e., the body containing all
operational components, to be easily lifted from the piping system for
servicing/replacement when the union nuts are backed off. Easy repair/
replacement, interchangeability, distribution availability, technical service,
and reliable quality are the synergistic rationale many plants and original
equipment manufacturers have embraced while standardizing on Chemtrol
True Union Ball and Check Valves.
The laying length of the body and the heavy-duty modified-acme threads
in the union connections to the body have not changed in the four distinct
models’ 40-year history of the valve. This permits fouled valve replacement
with a new body cartridge, which will fit the old union nuts. No change in
piping length is required.
The distinctive orange handle indicates “open/close” and direction of flow
at a distance. And molded-in arrows on top of the handle dictate rotational
direction to personnel for easy operation within 90° stops. For applications
requiring handle removal, the D-ring stem flats indicate "open/close" and a
molded-in arrow on top of the stem indicates flow direction.
The Evolution of Chemtrol
As a result of continuous testing and improvements since the inception of
the True Union Ball Valve, three distinct model changes have occurred. The
original True Union Model A design had a seat-carrier that slid into the
smooth bore of the valve body, held in place by the external nut and end
connector. Tightening the external nut adjusted the compression of the PTFE
seat onto the ball.
The first major evolution to the True Union Ball Valve, Model B, introduced
the Tru-Bloc concept, a functional safety feature. With this design a
separate threaded retainer locked the seat-carrier into the body and
prevented the seat-carrier from being extruded out of the valve body when
the external nut was removed. This change is intended to prevent pressure
on the other side of the valve from ejecting the internal components and
fluid medium out of the open valve end and to further prevent possible
injury to persons or property.
®
Ball Valves
®
The Model C seat-carrier design was modified to include an external thread
which mated into the valve body threads, eliminating the separate retainer.
This modification also eliminated the adjustment of the seat-carrier by the
external nut and end connector, resulting in a sealing envelope that was
independent of external forces. An energized O-ring was added under the
PTFE seat that provided automatic adjustment to compensate for seat wear.
This design modification continued the Tru-Bloc feature, preventing the seat
carrier from being extruded out of the valve body when the external valve
nut was removed.
Manufactured in PVC and CPVC through 2", the current Model D ball
valve’s seat-carrier internal threads and the external union nut threads
were strengthened to provide an increased pressure rating of 250 psi at
73°F and improved the pressure ratings at higher temperatures. The end
connector design was modified to provide wrench flats. The union nut
OD was changed to provide improved gripping for strap wrenches. The
Model D design continued the sealing envelope that was independent of
external forces with an energized O-ring under the PTFE seat that provided
automatic adjustment to compensate for seat wear. The Tru-Bloc® feature
was also retained.

Introduction
Materials
PVC
(Polyvinyl Chloride) PVC conforming to ASTM D1784, Classification 12454, formerly
designated Type I, Grade 1, is the most frequently specified of all thermoplastic piping
materials. It has been used successfully for more than 55 years in such diverse areas as
chemical processing, industrial plating, chemical drainage, fresh and wastewater treatment,
chilled and tower cooling water, deionized water manufacture and distribution, and irrigation
sprinkler systems. PVC is characterized by high physical properties and resistance to chemical
attack by strong acids and other oxidizers, alkalis, salt solutions, some organic chemical
solutions, and many other chemicals. However, it is attacked by non-ionic surfactants,
some vegetable oils (e.g., peanut), and many organic chemicals such as polar solvents (e.g.,
ketones), aromatics (i.e., benzene ring structure), and chlorinated hydrocarbons. The maximum
service temperature of PVC is 140°F. With a design stress of 2,000 psi at 73°F, the long-term
hydrostatic strength of PVC is as high as any of the major thermoplastic materials being used
for solid piping systems. PVC is joined by solvent cementing, threading, or flanging.
CPVC (Corzan®)
(Chlorinated Polyvinyl Chloride) CPVC conforming to ASTM D1784, Classification
23447, is a resin created by the post-chlorination of a PVC polymer. The material’s resistance
to chemical attack is almost identical to that of PVC. And the physical properties of CPVC
are very similar to those of PVC at 73°F, but the additional chlorine in the CPVC polymer
extends its maximum service temperature to 210°F. For example, the design stress for CPVC
is 2,000 psi at 73°F, identical to that of PVC. But its strength is only reduced to 500 psi at
180°F, as compared to 440 psi for PVC at 140°F. For more than 35 years, CPVC has proven to
be an excellent material for hot corrosive liquids, hot and cold water distribution, and similar
applications above the useful temperature range for PVC. CPVC may even be chosen over PVC
in the 110°F to 140°F temperature range because its higher strength-at-temperature, requiring
less frequent piping supports, can translate to a more favorable overall installed cost than
PVC. CPVC is joined by solvent cementing, threading, or flanging.
PVDF (Kynar®)
(Polyvinylidene Fluoride) PVDF homopolymer conforming to ASTM D3222, Type I,
Grade 2, is a tough, abrasion-resistant fluorocarbon material that has a design stress of
1,360 psi at 73°F and a maximum service temperature of 280°F. It has versatile chemical
resistance to salts, strong acids, dilute bases, and many organic solvents, such as the
aromatics (i.e., benzene ring structure), the aliphatics (i.e., paraffin, olefin, and acetylene
hydrocarbons), and the chlorinated groups. And PVDF is ideally suited for handling wet or dry
chlorine, bromine, and other halogens. However strong bases and some organic chemicals
such as polar solvents (e.g., ketones) and esters attack it. No other solid thermoplastic
piping material can approach the combined strength, working temperature, and chemical
resistance characteristics of PVDF. It is joined by the thermo-sealing socket fusion process,
threading, or flanging.
PVDF, absent of any color pigment, is transparent to ultraviolet light. So while PVDF is one
of the few plastic materials that is not degraded by UV radiation, exposure of the fluid
medium inside a piping system to direct sunlight can frequently adversely affect its stability.
Therefore, all PVDF piping components that Chemtrol produces for general chemical service,
contain an FDA-approved red pigment to mask the penetration of UV rays.

of metallic ions and foreign organic compounds. And since the resin does not require
processing or other external additives to aid manufacturing or long-term stability, the hardpolish surface of components will remain intact, so that piping systems will not release
particulate to the fluid medium. Further, there will be no surface micropores to encourage
biological growth. Natural Kynar

PP
(Polypropylene) PP as specified by ASTM D4101, is a member of the polyolefin family
of pure hydrocarbon plastics. Although PP has half the strength of PVC and CPVC, with a
design stress of 1,000 psi at 73°F, it may have the most versatile chemical resistance of
the thermoplastic materials identified as the sentinels of industrial piping. Consider the
fact that there are no known solvents for PP. As a result, it has been the material of choice
for drainage of mixed industrial chemicals for over 40 years. As pressure piping, PP has no
peers for concentrated acetic acid or hydroxides. It is also suitable for milder solutions of
most acids, alkalis, salts, and many organic chemicals, including solvents. The nemeses
for PP are strong oxidizers, such as the hypochlorites and higher concentrations of sulfuric,
nitric, and hydrofluoric acids. They are Environmental Stress Cracking (ESC) agents for PP,
meaning that time-to-failure is a function of the combined variables of concentration and
temperature of the fluid and stress. Although PP is not recommended for some organic
chemicals, such as polar and chlorinated solvents and the aromatics, the concern is
permeation through rather than catastrophic damage of the molecular chain.
Black PP used in Chemtrol products is formulated with a minimum 2.5% carbon black. The
plastic pipe industry recognizes PP formulated with this level of carbon black as suitable for
long-term outdoor service.

because of its extremely low content of metals, organic compounds other than naturally

Chem-Pure systems are intended as an economic alternative to the ultra high purity PVDF
systems typically found in the highly sophisticated electronic semi-conductor industry.

®
systems are intended for high purity chemicals or DI water.
FKM
(Fluoroelastomer) FKM is compatible with a broad spectrum of chemicals. Because
of this extensive chemical compatibility, spanning wide ranges of concentration and
temperature, FKM has gained wide acceptance as a material of construction for valve
o-rings and seats. These fluoroelastomers can be used in most applications involving
mineral acids (with the exception of HCl), salt solutions, chlorinated hydrocarbons, and
petroleum oils. FKM is not recommended for most strong alkali solutions.
EPDM
(Ethylene-propylene-diene monomer) EPDM is a terpolymer elastomer that has good
abrasion and tear resistance and offers excellent chemical resistance to a variety of salt,
acidic, and organic chemical solutions. It is the best material for most alkali solutions and
hydrochloric acid, but is not recommended for applications involving petroleum oils or
most strong acids.
PTFE
(Polytetrafluoroethylene) PTFE has outstanding resistance to chemical attack by most
chemicals and solvents. PTFE has a temperature rating of -200°F to +500°F. It is a selflubricating material used as a seat and/or bearing material in most Chemtrol
®
valves.
Chemical Resistance
While thermoplastic piping systems are useful in general water service because they are
light-weight, easy to install, and cost-effective, they excel in corrosive environments, such
as water and wastewater treatment, food and pharmaceuticals, chemical processing,
mining, power plants, oil refineries and more. Choosing the proper material for corrosive
fluids can be handled by consulting the NIBCO Chem-Guide and understanding the effect
that temperature will have upon plastic materials’ strength.
Chemical resistance is the ability for a particular plastic material to maintain properties in
contact with a chemical. To ensure comprehensive chemical compatibility, a piping system
must take into consideration the chemical resistance of all system components, including,
but not limited to, plastic components, solvent cements or thread pastes (if applicable),
elastomeric seals, all valve components and lubricants. Testing under field conditions may
be the best way to ensure selected materials will work in a particular application.

PVC and CPVC Tru-Bloc® True Union Vented
(Bleach) Ball Valve, Model D
The Problem
Sodium hypochlorite, used in water treatment, aquatic centers, and paper
and textile applications, can become trapped in the body cavity of a closed
ball valve and create conditions that may result in damage to the valve or
system as a result of unstable chemical decomposition.
The Chemtrol Solution
The Vented Ball Valve is a special factory modification to a PVC or CPVC
True Union Ball Valve that effectively vents sodium hypochlorite out-gassing
to the pressure port. In addition, the inner valve surfaces are kept constantly
wetted to ensure problem-free use of the ball valves in bleach transfer and
injection applications.
Background
In the search for a safer alternative to chlorine vacuum gas injection, fresh
and wastewater treatment, paper and textile plants, and aquatic centers are
converting to the use of sodium hypochlorite as a disinfectant or bleaching
agent. A high pH level characterizes commercial bleach, which consists of
a nominal 15% solution of sodium hypochlorite along with approximately
1-2% of sodium hydroxide to act as a chemical stabilizer. Known as a
good oxidizer, the solution has been found to cause stress cracking in
polyethylene and polypropylene materials. And metallic materials react,
causing rapid decomposition of the “hypo.” However, PVC and CPVC, with
fluorocarbon rubber (FKM) seals, have been successfully used for years to
handle this aggressive chemical solution.
www.chemtrol.com
Permanent Bleach
And Vent/Flow
Directional Marking
Some system design considerations are important, though. Heat, time, and
positive ions are enemies of bleach stability. When a ball valve is closed in
periods of inactivity, the bleach will decompose over time liberating oxygen
gas. The decomposition rate is increased by heat absorbed from sun shining
on exposed piping, or by reaction heat resulting from debris trapped in a ball
valve body between the ball and its seats. Gas pressure may slowly build in
the closed valve cavity, or quite rapidly in the reactive case. Such conditions
may result in damage to the valve or system.
Also, evaporation of sodium hypochlorite in the ball cavity can lead to the
formation of crystalline residue that eventually embeds in the PTFE seats of
a ball valve and significantly raises the turning torque due to excessive wear
on the ball by fouled seats. Such conditions may result in a broken valve
stem, frozen valve ball, or other damage to the valve or system.
The Chemtrol
hypochlorite transfer and injection applications. Our unique factoryassembled bleach ball valve has effectively eliminated the problems
associated with these uses. By ensuring that all inner surfaces of the valve
are kept constantly wetted and vented to the upstream side when the valve
is in the closed position, we have eliminated the conditions required for gas
accumulation and caustic crystallization in the body cavity.

off and on may direct flow from the branch center-inlet to one side run-outlet
(at the 0° stop position), then to shut-off (at the 90° position), and then to the
opposite side run-outlet (at the 180° stop position). The multiport may also
be used to alternately direct flow from either of the side run-inlet ports to the
branch center-outlet port, with shut-off at the mid-position (when handle is
perpendicular to the body). Cross-contamination of the two inlet streams is
prevented by all intermediate positions between the 180° stops.

possible pressure drop for 90° porting.
The Chemtrol True Union Diverter Valve is a 3-Way/3 Position
Ball Valve
It is used for applications where a quarter-turn will achieve diversion of flow,
but shut-off control is not required. When the handle is rotated 90°, the two
positions of on and on may direct flow from the branch center-inlet to one
side run-outlet (at the 0° stop position). and then the opposite side run-outlet
(at the 90° stop position). The diverter may also be used to alternately divert
flow either of the side run-inlet ports to the branch center-inlet port. The
internal porting of the diverter makes no provision for shut-off. Therefore,
the valve can be used for proportional mixing at all intermediate positions
between the 90° stops.
