Power Industry: Customer Testimonial

Control Valve Solutions for Critical Power Applications

May 2014 – Chief Electrician, Kentucky Utilities

I have had the Trimteck-Optimux OpGL Globe Control Valve installed for about 16 months. Mine is a severe duty socket-weld valve to reduce 1450psi/1000°F steam to 300psi steam to supply the air ejector for the turbine condenser.  The valve was designed to supply 750#/hour with one set of jets in service, and 1500#/hour with two sets of jets in service. The original sizing of the orifice was ¼”, however evaluation of the flow characteristics showed that the flow with two jets in service was reaching >90% of the valve opening. Trimteck resized the orifice to 3/8” opening and re-evaluated the characteristics. This was a much better fit, with the one jet in service being around 40% open and the 2 jets in service being around 60%.

The valve arrived on time, and we brought it to our shop to test and examine before installation. We hooked up air and stroked the valve. The positioner was on the valve 180° from where we needed to be. I called tech support and they were able to talk me through rotating the actuator 180°. It was really easy.

The valve was installed and nominal values were put into the control circuit in the DCS. It worked great with these numbers the first time the unit came on after outage. There were a few minor adjustments to the control numbers but within a week the valve was controlling to within 4-5psi. On startup the valve would operate from full open and close as the inlet pressure increased. The factory had predicted the valve to run at 40% open with one jet in service it runs at 39%. I was very impressed.

After about 10 months I noticed the valve was leaking at the stem packing. On a brief outage we tried to tighten packing, but we did not succeed in stopping the leak. Our annual outage was just a few weeks away so we decided to leave the valve in service and replace both upper and lower packing during the outage. I also decided to inspect trim as the valve had been in a severe service application for 12 months. We had not had an operating control valve in this application in 10 years, and I did not know what to expect when it was disassembled.

The valve was very simple to disassemble. We pulled the actuator and valve as an assembly and took it to our shop for further inspection and disassembly. We called tech support with one question and they were extremely helpful. The tech on the other end of the phone seemed to have assembled the valve I had on the bench. Upon inspection of the plug, seat, and stem there was no discernable wear whatsoever. Even where the packing had leaked there was no indication of wear. We reassembled the valve and returned to service. We have tightened the packing one time after that.

I am overall very happy with the performance of the valve. The ease of disassembly to me surpasses any valve that I have worked on (including Fisher). I currently have my Fisher valves rebuilt by an outside contractor. I will not hesitate to let my technicians work on this valve, and other than myself, at our facility there is very little valve experience.

I have 30 years of power plant experience and have worked with many types of valves in many different applications from low-pressure (dp) low temperature (such as water tank level control), to high pressure, high temperature (gland steam control). I am familiar with many brands (Copes Vulcan, Fisher, Leslie, and DFT). I consider the Trimteck to be as good as any you can buy. I however did not buy Trimteck because it was the cheapest or the best (I was unfamiliar with the brand). The biggest contributing factor was their ability to supply me with the valve I needed in the time frame I needed. I called a couple of references, both of who were pleased with their valves. I also went to the trimteck.com and gathered information. I am very glad I decided to go with Trimteck.  The wear characteristics seem to surpass the others, and the company has had the best tech support of any valve company I have worked with.

Custom Fabricated Bar Stock Bodies

OpGL-XTOpGL-XT Custom Fabricated Valves

In addition to our rugged, versatile line of standard Optimux OpGL Globe Control Valves, which are typically built with cast bodies in stainless or carbon steels, Trimteck also excels at engineering, designing, and manufacturing custom sliding stem valves with bodies fabricated from bar stock. We call these fabricated bar stock valves Optimux OpGL-XT Control Valves.

Why use a fabricated OpGL-XT?

Quick Lead Time – fabricated OpGL-XT bar stock bodies are not subject to foundry delays

Availability of Exotic Alloys – no limitation on construction material, which allows quick turnaround of valves fabricated from uncommon alloys

Availability of High Pressure Valves – the OpGL-XT can be machined up to ANSI Class 4500; again, with a faster turnaround than cast valves

Customizability – body styles, end connections, and face-to-face dimensions can all be customized as required

Severe Service – available with an array of severe service trims – including venturi seats for flashing service – as well as oversized wall thickness for noise abatement and added durability

Industry Spotlight: Natural Gas

OpTB Trunnion Ball Gas Plant Inlet Valve

Optimizing Gas Systems with Optimux Control Valves

As more and more natural gas is produced and brought to market around the world, gas handling, processing, and distribution systems must respond by pushing the envelope to ensure maximum capacity where and when it is needed. It follows that the requirements for control valve applications in these systems are becoming increasingly challenging and complex: from the need for noise attenuation technology, to effective and robust severe service trims for high differential pressures, to material hardening processes that reduce the erosive effect of particles in suspension. Not only must a control valve have the capacity to withstand these conditions, it must also perform with extreme precision and reliability in order to truly optimize the system.

Trimteck builds Optimux control valves that effectively and economically tackle these unique process conditions in natural gas systems. We manufacture a suite of flow control solutions for gas applications that include the OpTB – a dual-function trunnion-mounted ball valve with a characterized trim that allows for both accurate throttling and a bubble-tight shutoff – and the OpGL – a rugged, multi-purpose, custom-engineered globe control valve for applications ranging from extreme differential pressures and sour gas at the well-site, compressor station, or treating plant, to cryogenic applications at liquefaction plants.

CVD-5B Metal Hardening

Trimteck is at the forefront of applying innovations in material science to extend the life of process control equipment. First used in the aerospace industry to harden rocket nozzles on the space shuttle, CVD-5B is a chemical vapor diffusion process wherein a hard wear-resistant metal mesh is fused into the surface of a wide variety of ferrous and non-ferrous materials. We have altered and adapted the technology to make our control valves and parts last longer.

There are many metal hardening technologies on the market today, such as thermal sprays, stellite, and hard chrome facings. However, users are increasingly demanding that their process control equipment also be wear-resistant and capable of sustaining higher temperatures, and CVD-5B was developed as a cost-effective alternative for addressing these process control issues.

Unlike coatings and traditional hard facings that harden only the surface of the host material, during the CVD-5B process, superheated boron atoms are diffused deep into a host surface to form a metal boride layer that permeates evenly up to .015’’. Trimteck has harnessed and perfected this advanced technology to, in many cases, effectively extend the life of our control valves more than ten-fold.

  • Economical alternative to Tungsten Carbide
  • Corrosion resistant; acids and bases
  • Lends extended life to severe service trims
  • Resists temperatures of up to 1200 Degrees F
  • Reduces coefficient of friction
  • Not a ceramic, will not crack under duress

See our ad in Hydrocarbon Processing Magazine

Trimteck is featured in this month’s issue of Hydrocarbon Processing, which contains a special report on process and plant optimization and covers a series of issues relevant to the end user seeking to optimize his/her plant. The topics discussed in the report include: reliability performance to enable better risk assessment and identify root causes for potential catastrophes before they occur, several new tools and equipment to improve the prediction of refinery unit feed qualities and yields, and an overview of retrofit options for improving energy efficiency in distillate hydrotreaters. At Trimteck, we believe that selecting a reliable, rigid control valve is the first, and easiest step in optimizing a plant. A system, as it were, is only as effective and efficient as its component parts.
