Sun Introduces Electro-Proportional Cartridge Valves

Electro-Proportional Cartridge ValvesSun introduces the first of its new line of electro-proportional cartridge valves. This initial offering comprises both direct-acting and pilot-operated versions. The direct-acting models consist of proportional flow controls, pressure reducing/relieving cartridges, and a pilot stage relief. The pilot stage relief also provides the foundation for the pilot-operated proportional product line.

There are significant advantages to Sun's line of proportional products. These include:

  • An extensive array of proportionally controlled functions available in 2-, 3- and 4-port varieties
  • Flow capacities ranging from as low as 0.1 gpm (0,4 L/min) up to as high as 200 gpm (760 L/min)
  • Operating pressures up to 5000 psi (350 bar)
  • Sun floating-style construction eliminates the effects of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations
  • Functional interchangeability with Sun's non-electro-proportional products
  • Physical interchangeability with Sun's non-electro-proportional products of same function and frame size—i.e. same cavity and manifolds
  • Same coil as Sun's solenoid-operated, full-flow switching cartridges
