Hydraulics Online Valve Expertise: Sun Hydraulics cartridge valves and integrated packages for mobile and industrial applications
Sun Hydraulics is a leading manufacturer of high-performance screw-in hydraulic cartridge valves and manifolds – used to control force, speed and motion in industrial and mobile fluid power systems.
They offer standard manifolds in nearly limitless variety; custom manifolds can also be designed to meet specific customer requirements. Their cartridge valve 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.
Sun Hydraulics sells its products globally, primarily through independent distributors, to diverse markets of mobile and industrial equipment and machinery manufacturers. They offer products that advance customers’ businesses – improving the safety and performance of the machinery in which they are used.
Sun’s floating cartridge construction and cavity design allows products to operate precisely and reliably at higher pressures and flow rates in the most demanding applications. The generous porting area, coupled with their manifold design and construction techniques, results in integrated packages that can be up to 50% smaller than competitive offerings.
Sun Hydraulics Product Series Overview
Sun Hydraulics manufactures one of the industry’s most comprehensive ranges of screw‑in hydraulic cartridge valves, integrated manifold solutions and electro‑hydraulic controls. Their products are used across mobile machinery, industrial automation, energy systems, marine equipment and advanced hydraulic control applications. Sun valves are engineered for precision, low leakage, long service life and stable performance across a wide range of pressures and flow conditions.
