Sun Hydraulics has launched its new Sun FLeX™ family of competitively priced, high-performance electro-hydraulic products. These 25 completely new solenoid-operated cartridge valves, available in directional, electro-proportional and relief functions, and three new coils are the first products in the FLeX Series for 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.

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

- FPB* throttle normally closed (FPBF, FPBD, FPBG, FPBE) and normally open (FPBI, FPBM, FPBJ, FPBN) 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 740 Series high-power coils or the 747 Series explosion-proof coils as needed.
- 3000-psi (210-bar) valves use either the 740 Series low-power coils or the 747 Series explosion-proof coils as needed.

Electro-Proportional Blocking Poppet Throttle Valve
- The FPBU valve uses either the 740 Series high-power coils or the 747 Series hazardous locations coils as needed.
- This 5000-psi (350-bar) normally closed blocking poppet throttle exhibits a large degree of compensation in the 2-to-1 direction and provides proportional flow control in the 1-to-2 direction with the addition of an external compensator.
- Compatible with Sun's XMD mobile drivers for finely tuned control for demanding electro-hydraulics applications.

- RVC* valves are fully adjustable and offer ventable and blockable relief functions. They combine the functionality of two valves into one body and one cavity.
- Provide precise and dependable pressure regulation at flow rates up to 15-gpm (60 L/min) (RVCK and RVCL) and 25-gpm (100 L/min) (RVCM and RVCN) at 5000-psi/350-bar.
- Valves use the 740 Series High-Power Coils.
- 747 Series Hazardous Location (explosion-proof) Coils are also compatible.
740 Series Low- & High-Power Coils
- 740 Series comes in 12, 14, 24, and 28 Vdc and 115 and 230 Vac
- DIN 43650 Form A (IP65/IP67 rated) and Deutsch DT04-2P (IP69 rated)
- Low-power coil draws 17 W; high-power coil draws 25 W (at 20° C)
- Transient voltage suppression (TVS) diode is optional for dc coils and standard for ac coils
