A highly corrosive and toxic chemical with strong disinfecting properties, Sodium Hypochlorite plays an ever increasing role in many industries. However, its corrosive nature and tendency to release tiny gas bubbles that can permeate non-metallic pumps poses a major challenge to conventional pumping techniques.

A large utility company had a series of dams along a river which controlled the flow of water into the local area. These dams were deemed as a critical infrastructure by the Federal Energy Regulatory Commission. The spillways are controlled by large butterfly valves which are actuated utilizing hydraulics and they needed to be tested.

For a leader in industrial flow equipment and services, one specific application was causing significant difficulties for their end user. The harsh environment – high-temperature chlorinated gas for fiber optic production – was causing half of their pressure transmitters to fail. By working with WIKA’s experts in quality instrumentation on a custom pressure sensor solution, the customer overcame their systematic field problem with great success.

The wastewater treatment equipment market was worth over $35 billion in 2015, and is expected to reach more than $55 billion by 2023. Increasing demands for water, alongside a trend in recycling and reusing this precious resource, are two reasons for the growth. End-user industries – power generation, pharmaceuticals, paper, oil & gas, food & beverage and general industrial – are also driving the water treatment industry.

Several years ago, a major U.S. pharmaceutical plant suffered the loss of a full batch of an expensive drug because of contamination caused by a diaphragm seal failure.This failure of the seal on a measuring instrument allowed the diaphragm seal fill fluid to leak into the process media, leading to a shutdown of the production line, a quarantine of the product, and a time-consuming and very expensive investigation of what went wrong.

In geothermal plants, transforming the earth’s heat into electricity imposes challenging conditions on pressure measurement equipment. WIKA’s pressure monitoring instruments and diaphragm seals can withstand harsh environments, as shown in a recent installation at a geothermal well in Southeast Asia.

Chlorine dioxide is a powerful oxidant used in pre-treatment of drinking water for reduced trihalomethanes, as an oxidizing agent for contaminated water used in oil drilling, as a sanitizer in vegetable and fruit washing, as a biocide in cooling towers and its largest market the bleaching of pulp for paper. Chlorine dioxide is a very unstable compound and highly reactive, so typically it is made by generators placed on site.

Valin recently had the opportunity to bid on large specialized dampers for flue gas with a leading engineering and equipment firm. While working with engineers on a smelter environmental project, the Valin team assured them that Valin was very capable of supplying non-standard complex damper assemblies and would use the customer specified actuators with Valin specified controls and accessories. The firm agreed, and submitted a bid package for five 54” heavy duty all stainless dampers with actuators and controls.

A large energy company needed to lower costs, reduce maintenance and provide more reliable hydrogen-cooled generators for their customers worldwide. In order to monitor seal oil pressure remotely, provide switch control and be able to instantly view pressure readings, three discrete instruments were needed – a pressure transmitter, a pressure switch and a local gauge. Click on the "Read More" button below to find out how they were able to accomplish all of that with one product.

A public utility company needed a compact liquid metering solution with a minimal footprint. The company required a LACT unit that could not only accurately measure the produced liquid product, but one that could control the automated requirements and have an interface with truck drivers to load their trucks. Valin’s engineers collaborated over multiple meetings with the public utility company’s engineers to design a system that would satisfy accuracy, performance, and safety issues, as well as consider environmental concerns. Valin listened to the customer and created a system that would outperform older systems and still meet the many requirements.

Valin was approached by a company that purchases natural gas direct from the pipeline, processes it and transports it to CNG filling stations throughout California. They wanted a portable metering system which would allow them to confirm the mass quantities and chemical composition of the natural gas they were purchasing from the pipeline. Valin’s technical specialists designed a portable metering skid that would fulfill the customer’s needs and provided diagrams, drawings, and control schematics.

A hydrogen production plant was having to replace gauges every 30 days and needed a better solution. Valin’s technical specialists recommended an all-welded system gauge and installed it shortly thereafter. The special gauge can be used in many applications where vibration and temperature are a challenge and the customer has experienced on-going gauge failures. The gauge is well-suited for applications in refineries, chemical, power generation and all other critical process applications.

A major refinery was looking for a way to control the distribution and handling of instrumentation products during a dual turnaround. Valin was able to provide a locking cabinet and tubing rack for each side of the turnaround with on-site restocking capabilities. Valin’s material handling solution took the burden off the refinery’s planners and freed up their time to work on more important tasks. The planners no longer have to control or place restocking PO's.

During an observation at a refinery, chemists noticed the sample cylinders currently installed at their facility did not have the latest features specified by the Department of Transportation (DOT) / Cal-OSHA regulations.It was reported to the quality control division where the risk was recognized and resulted in an action item that the Maintenance & Reliability team had to resolve. Valin assessed the issue and recommended replacing the rupture disc with a bushing and relief valve, set at 1800 psi. The recommendation was reviewed with the Instrument Mechanical team leader, a QCD stake holder, the local PED representative for PRVs, the ETC sample gas cylinder subject matter expert, and the PRO maintenance planner/scheduler. Everyone agreed that the change should be implemented and Valin was called in to handle the installation.

A developer and manufacturer of molded-fiber packaging was struggling with controlling the consistency of the pulp feed stock in their manufacturing process. They tried numerous solutions with little to no success. This was due in large part to the fact that they were forced to use numerous vendors for the equipment needed to control their pulp consistency. Their supplies did not offer a full solution to measure, control, and automate their process. The outcome was an inconsistent product that would burn due to a thick pulp stock that dried too fast, or wet stock that took excessive time to dry and wasted time and resources.

There are 27 mines located in a geographically isolated area using fittings and tubing provided by Valin.  Unfortunately, Valin did not have a local office to support the mines with a bin stocking program. To combat this Valin looked at the areas local resources to see if we could partner up with a local vendor that is currently in the mines and can present Valin products to the mines. After an extensive search, a partner was found that had a good reputation and could expand our presence in the mines.
