Introducing 16 New FLeX Series Solenoid-Operated Directional Valves

New FLeX Series Directional Valves, Series DNB* and DMB*

New 3- and 4-way solenoid-operated directional valves in the FLeX product family provide robust electro-hydraulic control for mobile and industrial applications. When paired with Sun’s portfolio of pressure and flow-control valves, these new directionals can help you manage a complete range of functions such as direction, position and power in your most demanding applications. 

And with these new additions to the FLeX family, you can now create complete FLeX solutions for 3000- or 5000-psi (210- or 350-bar) applications that give you 10-million-cycle reliability, 1000-hour salt fog protection and industry-leading performance in a market-priced solution.  You’ll feel the difference with FLeX.

Three-Way Directionals, Series DMB*

The new DMBD (3000-psi/210-bar) and DMBF (5000-psi/350-bar) 3-way directional valves are direct acting and are offered in two spool types as shown here.

DMBD-XA* / DMBF-XA*The "A" spool creates an open bidirectional flow from 2 to 1 when de-energized, and flow 2 to 3 is blocked bidirectionally. When energized, it creates an open bidirectional flow path from 2 to 3 and blocks flow 2 to 1 bidirectionally.

DMBD-XN* / DMBF-XN*The "N" spool functions the opposite way. When de-energized, it creates an open bidirectional flow path from 2 to 3, and flow 2 to 1 is blocked bidirectionally. When energized, it creates an open bidirectional flow path from 2 to 1, and flow 2 to 3 is blocked bidirectionally.

FLeX Series DMB* valves use the new T-150A cavity. Sun standard manifolds are available for the T-150A cavity so you can start applying the DMB* valves now.  Explore the new manifold options by clicking here. 

Four-Way, Two-Position Directionals, Series DNB*

The new DNBD (3000-psi/210-bar) and DNBF (5000-psi/350-bar) 4-way, 2-position directional valves are direct acting as well and are offered in six spool types as shown here.

DNBD-XC* / DNBF-XC*The “C” spool creates a blocked flow path in all directions when de-energized. When energized, it creates an open bidirectional flow path from 3 to 2 and from 4 to 1.

DNBD-XD* / DNBF-XD*The “D” spool also creates a blocked flow path in all directions when de-energized.  When energized, it creates an open bidirectional flow path from 3 to 4 and from 2 to 1.

DNBD-XE* / DNBF-XE*The “E” spool creates an open bidirectional flow path from 3 to 4 and from 2 to 1 when de-energized.  When energized, it creates a blocked flow path in all directions.

DNBD-XN* / DNBF-XN*The “N” spool creates an open bidirectional flow path from 3 to 2 and from 4 to 1 when de-energized.  When energized, it creates an open bidirectional flow path from 3 to 4 and from 2 to 1.

DNBD-XT* / DNBF-XT*The “T” spool creates an open bidirectional flow path from 3 to 1 and blocks 2 and 4 when de-energized.  When energized, it creates an open bidirectional flow path from 3 to 2 and from 4 to 1.

DNBD-XV* / DNBF-XV*The “V” spool creates an open bidirectional flow path from 3 to 4 and from 2 to 1 when de-energized.  When energized, it creates an open bidirectional flow path from 3 to 1 and blocks 2 and 4.

FLeX Series DNB* valves use the new T-30A cavity. Sun standard manifolds are available for the T-30A cavity so you can start applying the new DNB* 4-way directional valves now. Explore these new manifold options by clicking here.


The FLeX Advantage

FLeX LogoSun applied 50 years of valve design experience to the FLeX Series concept. We studied the future of fluid power, benchmarked the competition on performance and price and applied what we learned to develop the next-generation FLeX solenoid-operated valves. 

With the addition of these new directional valves, Sun now offers 28 FLeX Series directional valves, nine proportional valves and four relief valves.  That's a total of 41 solenoid-operated valves that deliver the FLeX Advantage. Like the other FLeX valves, these new directional valves offer key advantages:

  • High reliability - designed and tested to 10-million operational cycles at full rated pressure. 
  • Zinc-nickel plating standard for 1000-hour salt fog protection
  • Interchangeable coil options include the 740 Series high-power coils for 5000-psi/350-bar valves and low-power coils for 3000-psi/210-bar valves.  All FLeX valves can use the 747 Series hazardous location coils. (See below for more detail.)
