Tru-Tech Design


Tru-­Tech valves were designed using the latest engineering technology, which insures customers that the valves installed in their system will provide the maximum degree of performance and the longest possible service life. 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 products. Parts manufactured today are 100% interchangeable with parts made many years ago and well into the future.

Tru-Tech Design

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 B.16.10 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 Enhanced 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.

WHY DO TRU-TECH DIAPHRAGM VALVES LAST LONGER?

The Tru-­Tech valve reduces diaphragm flex by contracting the vertical height of the flow area 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 a longer diaphragm life.

TRU-TECH ADVANTAGES
In addition to many features found in all diaphragm valves, Tru‐Tech has some extra advantages of its own.

Our diaphragm valves are available in two face-­‐to-­‐face configurations. Tru­‐Tech 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. Tru-­Tech also meets ANSI B16.10 standards, permitting direct replacement of most brands of gate, plug, and ball valves.

Tru-­Tech STRAIGHT THRU valves are available with TFE faced diaphragm that expands the range of applications that can be handled. This is a feature not offered by other brands of diaphragm valves.

All Tru-­Tech manual valves are furnished standard with travel stops. Travel stops help to prevent the number one cause of failure and reduced life in diaphragm valves, mainly “over-­‐ closure by zealous 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 number two cause of failure in other brands of diaphragm valves.

All Tru-­Tech “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 number of operations. All Tru-­Tech valves can be “rodded out” where clogging occurs, on other brands only Straight Thru valves can be rodded out. Tru-­Tech manufactures its own pneumatic actuators providing our customers with one source responsibility for the total package. All Tru-Tech 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 to insure lining thickness and integrity.
