Clark Cooper

What Clark Cooper does

Clark Cooper is a U.S.-based custom solenoid valve manufacturer operating as a division of Magnatrol Valve Corp. out of Roebling, New Jersey. Founded in 1968 (with brand heritage traced to 1903 and over a century of continuous operation), the company designs and builds high-pressure and specialty solenoid valves rated up to 15,000 PSIG, serving industrial B2B customers in oil and gas, hydrogen, compressed natural gas, power generation, navy and marine, cryogenics, aerospace, and specialized industrial applications. Core product families include the EH and EX Series high-pressure solenoid valves (up to 15,000 PSI), the EP70 pilot-assisted valve, the ER Series rotary valves with exotic material options (Naval Bronze, Hastelloy, Monel, stainless steel), the EV Series specialty valves, and MIL-SPEC Navy/Marine trip valves. Differentiated technical content includes cartridge-style designs for hydrogen, explosion-proof coils (ETL, ATEX), and conformance to MIL-S-901D shock and MIL-STD-167-1 vibration standards.

The business model is engineered-to-order hardware sales. Pricing is quote-based via a website "Get a Quote" workflow, phone, and email; standard EH/EX products ship in 1-3 days while EP70 builds run approximately 10 weeks. The company sells direct with no disclosed reseller or distributor network, supported by a small technical sales team (11-50 employees). Go-to-market relies on a content-rich website, application-specific landing pages, technical comparison charts, and a modest social media presence. Revenue mechanics are project-driven, configuration-driven, and certification-gated rather than high-volume catalog distribution.

Customer segments are organized by use case across at least eight verticals. Hydrogen applications (refueling stations, generation, fuel cells) and oil and gas are primary, followed by CNG, power generation, and navy/marine; aerospace, cryogenics, and specialized industrial are secondary. The company holds ISO 9001, ETL (UL/CSA hazardous-location), CRN for all Canadian provinces, ATEX for the EU, and multiple MIL-SPEC certifications, which collectively define its addressable market and act as the principal barrier to entry for competing solenoid valve suppliers.
