Sun FLeX™ Series Solenoid Valves & Coils:
Performance driven. Market priced.

FLeX Series Solenoid Valves & CoilsSun Hydraulics has just launched its new Sun FLeX™ family of competitively priced, high-performance electro-hydraulic products. These 16 completely new solenoid-operated cartridge valves and three new coils are the first products in the FLeX Series Solenoid Valves for both the mobile and industrial hydraulics markets.

Designed to outperform comparable valves in the market, FLeX Series solenoid valves deliver what you're looking for in a range of solenoid valves:

  • Consistently better pressure drop in a virtually leak-proof poppet-style valve
  • Designed and tested to exceed 10-million-cycle operations
  • Zinc-nickel plating standard (1000-hour salt fog) on valve and coil
  • Coil options that include interchangeable low-power, high-power and hazardous location (explosion-proof) versions for expanded configuration flexibility.
  • Valve and coil package that delivers a perfect market-priced solution.

The FLeX Series valves use Sun’s unique floating-style design, adding an extra layer of security in those harsh applications where torque and force can become excessive. FLeX Series products are available for order now through your local Sun distributor and begin shipping in January, 2018.

FLeX Performance Advantages

FLeX valves offer significant performance advantages over competitive valves. For example, the FLeX DTBF normally closed, direct-acting blocking poppet valve, like all the FLeX valves, was designed with advanced Computational Fluid Dynamics (CFD) simulation tools to optimize flow path geometries. It is coupled with a solenoid actuator that provides optimized actuation force at critical points in the valve stroke. The result, as shown in the performance curves, is the following:

  • Lower pressure differential across the valve at a given flow rate
  • Increased shift performance at higher pressures and flows.

Performance Comparison - Sun's DTBF vs Competition

In practice, this means hydraulic systems utilizing the DTBF valves will see significant improvements in both efficiency and reliability while providing higher pressures and flow rates over competitors' products.

FLeX Phase 1 Products

The initial FLeX Series introduction includes the following:

Four Two-Way, Direct-Acting, Solenoid-Operated Directional Blocking Poppet Valves (Normally Closed and Normally Open)

FLeX DTAF & DTBF
FLeX DTAF & DTBF
  • DTAF pilot-capacity models leverage Sun's T-8A cavity design and can be used to pilot larger, higher-capacity valves. (Shown at left)
  • DTBF directional valves use the Sun T-162A cavity.
  • Both models can use any of the three coil types (740 Series low- and high-power and 747 Series explosion-proof) in the normally closed version.
  • Neither valve requires hydraulic pressure for operation.

Eight Two-Way, Two-Stage Solenoid-Operated Directional Blocking Poppet Valves (Normally Closed and Normally Open)

FLeX DFB* Family
DFB* valve without coil
  • DFB* 10-gpm (40 L/min) valves offer either 3000-psi/210-bar (DFBD, DFBE) or 5000-psi/350-bar (DFBF, DFBG) maximum operating pressure with improved pressure drop and reliable operation across their full operating range.
  • 3000-psi valves use the 740 Series Low-Power Coils.
  • 5000-psi valves use the 740 Series High-Power Coils.
  • Both use the 747 Series Hazardous Location (explosion-proof) Coils.

Two Normally Closed & Two Normally Open Pilot-Operated Electro-Proportional Throttle Valves

FLeX FPB* Electro-Proportional Throttle Valves
FLeX FPB* Electro-Proportional Throttle Valves
  • FPB* throttle normally closed (FPBF, FPBG) and normally open (FPBI, FPBJ) valves offer excellent command-versus-flow and pressure differential-versus-flow performance.
  • Compatible with Sun's new XMD mobile drivers for finely tuned control for demanding electro-hydraulics applications.
  • 5000-psi (350-bar) valves use either the FLeX 740 Series high-power coils or the 747 Series explosion-proof coils as needed.
