FLeX Series
All FLeX Series valves incorporate the Sun oating-style construction to minimize the possibility of internal
parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
Designed and tested to 10-million operational cycles at full rated pressure
Exceeds the new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
Higher ow rates than competing valves of similar size.
Extremely low leakage – 0.004 in (0,07 cc)/min (1 drop/min)
Designed using CFD simulation for optimized geometries.
Zinc-nickel plating standard for 1000-hour salt fog protection.
Direct actuated and requires no minimum hydraulic pressure for operation.
Manual push-version override options are available in the "A" poppet congurations (DWBF-*A*). The force on
the "M" manual override must not exceed 25 lbf (110 N).
Suitable for load-holding applications when using the normally closed option. See the website for more
information.
A wide variety of coil termination and voltage options are available, with and without surge protection. See the
CONFIGURATION section.
Can be used with high-power (25-W) and hazardous location coils.
Coil connector options oer ratings up to IP69K. See individual coil product pages for details.
TECHNICAL FEATURESS
SERIES 0, CAVITY: T-150A3WAY, DIRECTACTING, SOLENOIDOPERATED
DIRECTIONAL BLOCKING POPPET VALVE
TECHNICAL FEATURES
The 3-way, two position directional poppet valves are direct
acting and feature a pressure-balanced design. They are
comprised of a coil nut (1), a solenoid with coil (2), a hex
body (3), a spring (4), a poppet (5), and two valve seats (6, 7).
DWBF-*A* (Normally Open 2 to 1, Closed 3 to 2)
Function: When de-energized, the poppet(5) is pulled
against the valve seat (6) by the spring (4), closing the valve
in the 3 to 2 ow path and allowing unidirectional ow in
the 2 to 1 ow path. When energized, the solenoid with coil
(2) pushes the poppet (5) o the seat (6) onto the other seat
(7), allowing unidirectional ow in the 3 to 2 ow path and
blocking ow in the 2 to 1 ow path.
DWBF-XN* (Normally Open 3 to 2, Closed 2 to 1)
Function: When de-energized, the poppet (5) is pushed
against the valve seat (7) by the spring (4), closing the valve
in the 2 to 1 ow path and allowing unidirectional ow in
the 3 to 2 ow path. When energized, the solenoid with coil
(2) pushes the poppet (5) o the seat (7) onto the other seat
(6), allowing unidirectional ow in the 2 to 1 ow path and
closing the valve in the 3 to 2 ow path.
