A History of Innovation

Founded in 1884 as the Reliance Gauge Column Company, Clark-Reliance ® has a long and rich history that abounds with innovation. It all began with what would be the company’s first breakthrough product a low water alarm for boiler operators. Using floats attached to a steam whistle, this revolutionary device would sound an alarm when water conditions became unsafe. Although the first, this is just one of the many pioneering products the forward-thinking engineers at Clark-Reliance have developed throughout the years.

Consistently on the forefront of technological progress, Reliance Gauge was also the first company to offer remote water gauges. The company received the ultimate validation of this product’s excellence during World War II when Reliance Gauge was called on to supply the U. S. Navy with all of its remote water gauges. Subsequently, to acknowledge Reliance Gauge’s outstanding efforts in this capacity, the U.S. Navy recognized the company with the prestigious Navy “E” Award.

As Reliance Gauge moved into the future, a number of other significant milestones and achievements also became a part of its impressive history. In 1962, Harry E. Figgie Jr., a Cleveland industrialist, acquired Clark Manufacturing Company. Founded in 1908, the company was well known as a leading supplier of steam traps, strainers, regulators and steam separators. Though their product offerings were quite different, Reliance Gauge and Clark Manufacturing shared a similar reputation for excellence and incredible growth potential. Ultimately, on February 19, 1963, Clark Manufacturing and Reliance Gauge Column were merged into one company: The Clark-Reliance Company. Despite the significant changes the company has undergone since it was founded over 100 years ago, Clark-Reliance remains a leader in innovation today.

Clark-Reliance Today

Clark-Reliance is dedicated to supplying the largest and broadest product line in the instrumentation industry for all types of measurement and control. Key acquisitions over the last few decades have solidified Clark-Reliance as a leader in the separation and filtration industries as well.

Clark-Reliance now includes a number of distinguished product lines: Jerguson®, Jacoby-Tarbox®, Magne-Sonics®, Anderson® Separator and National Filtration Systems®.

In 2014, years of growth and numerous acquisitions led to a corporate-wide reorganization. Today, each of the company’s product lines falls under one of three new operating groups: Clark-Reliance Instrument and Controls Group, Clark-Reliance Filtration Equipment Group and Clark-Reliance Filter Elements Group. The new organization has allowed for a more unified, integrated, service-driven corporation. The incredible success Clark·Reliance has experienced over the past several years has resulted in the need to amplify the floor space at the company’s manufacturing headquarters. A 2016 plant expansion recently added 21,000 square feet to the Strongsville, Ohio facility. Clark-Reliance’s extensive variety of products and solutions are constantly updated to integrate the newest technology. The company’s main goal is to provide world-class customer service, quality products and innovation to the petrochemical, refining and power generation industries. The years to come holds great promise for Clark-Reliance as the company continues to diversify their product lines and seek new acquisitions.


ANDERSON® SEPARATOR was founded in 1855 by a 25-year-old boilermaker named Valerius D. Anderson. He designed a very efficient steam cleaning and purification process for steam boilers. This centrifugal separator quickly became the industry standard for the removal of solids and liquids from steam. The new units quickly found applications in many other industries ranging from food processing to steel making. As Anderson Separator grew, so did its line of separation equipment. Anderson Separator became part of the Clark-Reliance family in the late 1980s and has continued to grow its business in the compressed air, steam, gas and power generation industries.

HYCOA History

For decades, industry has been living with sub-optimal transfer valves as a means to control fluid flow through redundant filters and coolers.  These cast plug valves had two primary draw backs, frequent leakage to the offline vessel and extremely difficult operation.  Despite the presence of several competitive vendors, the traditional designs went unchanged for years. This set the stage for HYCOA's CEO, Jay Williams to revolutionize the transfer valve back in 1980 with our patented resilient seal shoe.  For the first time, "Zero Leak" and "Transfer Valve" became terms that could be used together. This new and innovative approach to an old problem offered industry additional advantages.  Features such as zero friction drag during changeover and a positive mechanical lockdown device have turned the JR-33 into a favorite of design and maintenance engineers as well as plant operators.


Of course, success breeds imitation and several other new transfer valves have sprung up in recent years.  However, our patented design is still the only one with retractable, fully covered elastomer shoes.  This feature is important to reduce operating torque.  The retraction feature also avoids dragging an o-ring seal around the valve body bore and causing potential seal wear or damage. Past, present and future, HYCOA's commitment and focus is with the customer who requires top performance from their transfer valves.  We understand the requirements of duplex filter systems, heat exchangers and other critical API auxiliary lube oil systems.  WE also understand the requirements of our customers who simply want top performance in their transfer valve.
