Sun Hydraulics



Sun Hydraulics designs and manufactures high performance screw-in hydraulic cartridge valves and manifolds which are used to control force, speed and motion as integral components in fluid power systems. Sun's products allow machine designers to develop innovative and efficient control systems for all types of capital goods. Our hydraulic valves and packaged manifold systems work accurately and reliably, no matter how demanding the application.

Sun's cartridge valves provide pressure, flow, logic, directional and load control and are available in up to 5 sizes (capacities). Flow capacity ranges up to 400 gallons per minute and cartridges are designed to operate at pressures up to 5,000 pounds per square inch. Sun's standard manifolds are offered in an almost limitless variety, including direct mount, line mount, sandwiches, subplates and motor mounts. Custom manifolds can be designed for customer circuit requirements to provide a unique, application specific control system. All manifold products are offered in two basic materials – T6061 aluminum and ductile iron.

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's floating style cartridges provide a myriad of benefits to the user:

  • Reliable operation when installed in a cavity manufactured with Sun cavity tools
  • Reliable operation at high pressures
  • Superior cartridge retention in severe duty applications
  • Higher capacities relative to physical size
  • Low internal leakage rates
  • Smaller manifolds
