Company Profile

Founded In 1970, Robert E. Koski and John Allen co-founded Sun Hydraulics Corporation, Sarasota, Florida, to develop and manufacture screw-in hydraulic cartridge valves and manifolds for industrial and mobile markets. In January 1997, 2,300,000 shares of common stock were sold in an initial public offering. The Company has paid a dividend every quarter since going public. Products Sun Hydraulics is a leading designer and manufacturer of high performance screw-in hydraulic cartridge valves and manifolds which control force, speed and motion as integral components in fluid power systems. Everything we do at Sun, from design to manufacturing, is done with one objective in mind: to provide distinctive designs and reliable solutions. Our hydraulic valve and packaged manifold systems work accurately and reliably, no matter how demanding the application.. Cartridge products are available in up to 5 sizes (capacities), are capable of handling flows up to 400 gallons per minute, and operate at pressures up to 5,000 pounds per square inch. Product Differentiation Sun Hydraulics' screw-in hydraulic cartridge valves feature a unique, two piece, floating construction. This design allows working parts in the cartridge to freely move in relation to the fixed position of the cartridge in its cavity, thus producing a high level of performance and a high degree of reliability. Sun Hydraulics manufactures one of the most comprehensive ranges of standard screw-in hydraulic cartridge valves and manifolds in the world, and also develops and manufactures custom manifolds. Our Culture Our workplace is as distinctive as our products, and provides just as many advantages. We have no job titles, no hierarchy, no formal job descriptions, organizational charts or departments. We have open offices, promoting open communication. Each member of our technologically skilled, cross trained workforce is trusted to take the initiative and invent new ways to serve you better. This results in innovative products and processes delivered by a motivated workforce. As engineers, idealists and entrepreneurs, we're always on the lookout for emerging market needs and creating innovative ways to fill them. Manufacturing Sun Hydraulics is a process intensive manufacturing company that extensively employs computer numerically controlled (CNC) machinery and robotics. Automation is utilized throughout manufacturing areas to ensure consistent product replication and to promote manufacturing efficiencies and workplace safety. Where commercial machinery is not available for specific manufacturing or assembly operations, Sun Hydraulics often designs and builds its own machinery to perform these tasks. The Company has the ability to manufacture all components of its products with the exception of raw materials, springs and seals. Global Operations Sun Hydraulics has operations in the United States, the United Kingdom, Germany, France, Korea, China and India. There are three United States facilities, two in Sarasota, Florida and one in Lenexa, Kansas. The two Florida facilities are the primary locations for cartridge manufacturing. One of the Florida facilities and the Kansas facility manufacture standard and custom manifolds. The Coventry, England and Erkelenz, Germany operations act as European distributors of Sun's products and also manufacture manifolds. The operation in France is a technical sales and support office. The Korean operation distributes Sun products and manufactures manifolds for the local market. Sun’s China operation in Shanghai is a joint venture. The China plant incorporates Sun cartridge valves into manifolds designed and manufactured in China. The operation in India is a technical sales and support office in Bangalore. Market The global market for non-aerospace hydraulic valves is approximately $3 ½ billion (US$). The segment Sun Hydraulics participates in, screw-in hydraulic cartridge valves manifolds and integrated packages, is believed to represent approximately $1.3 billion. Sun Hydraulics believes that the screw-in hydraulic cartridge valve, manifold and integrated package market will continue to grow at a faster rate than, and at the expense of, the overall hydraulic valve market because of the myriad benefits associated with screw-in cartridge valves. Fluid Power Industry Sun Hydraulics is a member of the National Fluid Power Association and the British Fluid Power Association. Fluid power is one of the methods of transmitting power and controlling motion, along with mechanical and electrical technologies. A typical hydraulic system contains a pump to generate pressure, actuators to convert pressure into force, and valves and manifolds to control force, speed, and motion.
