Clark Cooper - A Division of Magnatrol Valve Corp.

Clark Cooper is a manufacturer of solenoid valve products who offers personal solutions not just standard product lines. There are many valve manufacturers who make `off the shelf` solenoid valve products. They may even offer a variety of metals and optional components for industrial applications. But as corrosive chemicals, abrasive materials, temperature extremes and high pressures begin to disqualify standard product lines and producers, finding a suitable product and willing vendor becomes a sourcing challenge. Today, engineers, researchers, maintenance departments, purchasing managers, and others involved in identifying solenoid valve solutions have to go through a variety of channels.

In 1914, Mr. Clark Cooper founded the Clark Cooper Company in response to a request from the US Army. Klaxon horns, manufactured in France, were needed for the production of US military vehicles. As a result of the German invasion in WWI these horns were no longer available. Mr. Cooper established the company in Philadelphia and began to produce horns and other signaling equipment.

From 1914 to 1944 Mr. Cooper invented and patented whistles and pneumatic signaling equipment for locomotive and rail systems. Many of the bronze horns and whistles made in Philadelphia are still in existence today.

In 1944 The Clark Cooper Company was moved to Palmyra, NJ and began to diversify their product lines. Palmyra, located across the river from Philadelphia, allowed the company to sell signaling equipment to the Navy during WWII. Most notably during that time was the rapid construction of Liberty Ships by the Navy.

After the war, the company looked to expand into other markets and began to develop a line of chemical metering pumps. This line of pumps became very attractive to a Midwest chroming company, Hooker Electrochemical, who purchased Clark Cooper Company in 1961.

In 1968 Clark Cooper Co. was sold to William Hagan who would operate the business in Palmyra, Riverton and Cinnaminson, New Jersey until 2002. During his long tenure, the company continued to manufacture and sell signaling equipment and chemical metering pumps. Also during this time a relationship with Magnatrol Valve began to form as Mr. Hagan began to manufacture valves. With a focus on military applications, Mr. Hagan would purchase general service solenoid valves from Magnatrol and modify them to meet Navy requirements.

This relationship with Magnatrol provided the opportunity for the company to be acquired by Magnatrol Valve Corp. in 2003. The company has since narrowed its focus to concentrate solely on designing and manufacturing solenoid valves for specialty applications. There have been numerous investments in engineering and production capabilities that resulted in new high pressure valve product lines, third party certifications and drastically reduced lead times.

In 2013, due to expansion and growth, the company relocated its headquarters to a larger facility in Roebling, New Jersey.

After 100 years of business, we want you to know that the same 1914, Made-In-America standards go into every one of our versatile solenoid valve products. As a Clark Cooper customer, you can count on a responsive technical support team, faster deliveries and famous Clark Cooper innovation for years to come.
