TTV DIAPHRAGM VALVES “The Best of the Best”
Compact Diaphragm Valves have a face to face that is
interchangeable with most solid wedge, double disc and
resilient wedge gate valves as well as most short pattern
plug and ball valves using ANSI B16.10 as a standard. These
valves are the best for O.E.M.’s and other usage on new
projects. Straight Thru valves are referred to as Tru-Flow and
Weir valves as Tru-Trol.
Standard Diaphragm Valves have a face to face that is
interchangeable with most other brands of diaphragm valves using
MSS SP-88 as a standard. These valves are used on replacement projects where existing piping integrity must be maintained. Straight Thru
valves are referred to as Maxi-Flow and Weir valves as Maxi-Trol.
TRU-TECH valves were designed on “CAD”, and into each and
every valve is incorporated the latest available state-of-the-art
engineering technology. This insures TTV customers that valves
installed in their system will provide the maximum degree of
performance and the longest possible service life.
TRU-TECH valve parts are manufactured on the latest state-of-the-art
CNC machining and turning centers. This assures our customers of
the highest possible quality parts. Parts manufactured today are
100% interchangeable with parts manufactured many years ago
and far into the future.
TRU-TECH “Diaphragm Valves” are quality checked, assembled and
tested by skilled technicians who take pride in their ability to
integrate old world craftsmanship into modern high-tech products.

DIAPHRAGM VALVE STANDARD FEATURES & ADVANTAGES
All brands of diaphragm valves have common design features that are
unavailable in other type valves. These unique advantages include in-line
maintenance, positive bubble-tight closure, bonnet isolation, no packing
glands, and a streamlined flow passage without recesses or pockets.
A pliable rubber diaphragm, seals, leak-tight against the valve body and at
the same time completely isolates all the mechanical working parts of the
valve’s operating mechanism from the fluid. This total separation between
the media passing through the valve and the bonnet also eliminates
troublesome stem seal and packing gland problems as well as providing
“fugitive emission” protection.
A wide range of rubber and plastic body linings and diaphragm materials
provides a cost-effective solution to readily handling corrosive and abrasive
liquids as well as liquids with suspended solids.
Providing simplified in-line maintenance has become increasingly more
important in valve selection. All sizes and types of diaphragm valves
provide this important feature.
Diaphragm valves do not seize up like eccentric plug valves and are excellent
for replacing problem valves in the field.
TO SELECT THE PROPER DIAPHRAGM VALVE
FOR YOUR APPLICATION, THE FOLLOWING
QUESTIONS MUST BE ADDRESSED:
1. SERVICE CONDITIONS? What is the fluid being handled? It
could be hydrochloric acid, tap water or something in between.
Note also that it could be a combination of two or more things.
2. CONCENTRATION OF FLOWING FLUID? The concentration
affects the proper choice of body lining and diaphragm material.
3. SYSTEM OPERATING TEMPERATURE? Many chemicals are
more aggressive at elevated temperatures. Plus, body linings
and diaphragm materials are pressure/temperature rated.
4. SYSTEM OPERATING PRESSURE? Most diaphragm valves are
pressure limited. Consult manufacturers recommendations for
system compatibility.

TTV DIAPHRAGM VALVE EXTRA FEATURES & ADVANTAGES
In addition to the many features found in all diaphragm valves,
TRU-TECH has some extra advantages of its own. TTV diaphragm
valves are available in two (2) face to face configurations. TTV
meets MSS SP-88 standards permitting direct replacement of
most other brands of diaphragm valves to be used where
customers are upgrading existing systems utilizing diaphragm
valves. TTV also meets ANSI B16.10 standards, permitting direct
replacement of most brands of gate, plug and ball valves.
TTV STRAIGHT THRU valves are available with a TFE faced
diaphragm which expands the range of applications that can
be handled. This is a feature not offered by other brands of
diaphragm valves.
All TTV manual valves are furnished standard with travel stops.
Travel stops help to prevent the No. 1 cause of failure and reduced
life in diaphragm valves, mainly “over-closure by overzealous
operators.” All pneumatically operated valves are available with
optional travel stops and are furnished as standard where our
engineering department feels the operator may be oversized.
All diaphragms are double studded providing an extra margin of performance, especially in vacuum service.
Stud pull out is the No. 2 cause of failure in other brands of diaphragm valves.
All TTV “manual valve operators” are supplied with “heavy duty acme threads” capable of providing heavy
thrusts and thousands of operations. Some other brands use limited duty v-threads not recommended for a
great numbers of operations. All TTV valves can be “rodded out” where clogging occurs. On other brands only
STRAIGHT THRU valves can be rodded out. TTV manufactures its own pneumatic actuators providing our
customers with one source responsibility for the total package. All TTV valves are furnished with position
indicators showing whether the valve is open, closed or throttling. Unlined valve bodies and all operators are
powder epoxy coated inside and out with a hybrid flex/epoxy powder formulated for maximum chemical as
well as weather resistance. Plastic lined valves are furnished with bodies completely encapsulated with the
latest state of the art fusion-bonded liner. Each and every valve body lining is spark tested in wetted areas to
ensure lining thickness and integrity.
Why Do TTV Diaphragm Valves Last Longer?
The TTV valve reduces diaphragm flex by contracting
the vertical height of the flow area and by expanding
the width. The resultant body shape provides the
laminar flow characteristics of a venturi and less
turbulence to the flow media. In addition, the
reduced flex results in longer diaphragm life.

ASTM A-126 Class B
CAST IRON
A general purpose material suitable for water, air, petroleum products, most solvents, dry powders, and a
wide variety of chemicals when used in the unlined state. Can be lined with a wide variety of rubbers and
plastics to handle almost any process media. (low cost)
DUCTILE IRON
ASTM A-536-GR 65-45-12
A general purpose material with usage similar to cast iron. Ductile iron however is much stronger and more
capable where there may be high pipeline stresses, danger from impact, or concern from leakage upon line
or valve fracture. Normally ductile iron can be used as a direct replacement for steel valves. Can be lined
with a wide variety of rubbers and/or plastics to handle almost any process media. (medium cost)
CAST STEEL
ASTM A-126, GR WCB
Another general purpose material somewhat less resistant to corrosion than cast iron especially where
water is the media. Steel is much stronger and like ductile iron much more capable where there may be
high pipeline stresses, danger from impact or concern from leakage upon line or valve fracture. Steel valves
are expensive and normally only used where specified by the end user. Can be lined with a wide variety of
rubbers and/or plastics to handle almost any process media.
316 STAINLESS STEEL ASTM A-351 GR CF8M
An alloy of iron, carbon, nickel and chromium. Suitable for most foods, beverages, pharmaceuticals, solvents,
sea water, oils, and some acids and alkalies.
ALLOY 20 ST.ST.
ASTM A-351 GRADE CN-7M
Has higher amounts of nickel and chromium than 300 series stainless steels. It is more resistant to sulfuric
acid and is used widely in chemical processing and water treatment.
Note: Other “Body Materials” are available as an option; call our Sales Department for details.

with only moderate oil resistance. Also good in certain chlorine service, for alkalies and is abrasion resistant.
VITON ® (FKM) -20 degrees to +300 degrees F
Offers exceptional resistance to oils, most chemicals and many solvents at elevated temperatures. It can be used in most
applications involving mineral acids, salt solutions and chlorinated hydrocarbons. Viton is not recommended for ammonia, its
derivatives or polar solvents, E.G. Acetone. Very costly, but sometimes works where others fail.
MATERIAL AVAILABILITY
TEFLON ® TFE/EPDM -30 degrees to +300 degrees F
TFE is simply the most chemical resistant of all the diaphragm materials. It is good for handling strong acids, alkalies (caustics) and solvents. Because of its greater stiffness, it significantly increases required closing/sealing forces and on automatic
valves may require a larger size actuator and has a shorter working life than elastomer diaphragms.
BUTYL -20 degrees to +250 degrees F
A good choice for gases because it has very low vapor and gas permeability. Also good for many acids and alkalies. Good
for applications involving steam sterilization.
