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.
Zinc-nickel plating standard for 1000-hour salt fog protection.
Designed using CFD simulation for optimized geometries.
A wide variety of coil termination and voltage options are available, with and without surge protection. See the
CONFIGURATION section.
Coil connector options oer ratings up to IP69K. See individual coil product pages for details.
The 3000-psi (210-bar) DNBD valves use the low-power (17-W) coils; the 5000-psi (350-bar) DNBF valves use the
high-power (25-W) coils. Note that all DNB* valves can be used with the hazardous location coils. See table on
page 3.
TECHNICAL FEATURESS

SERIES 0, CAVITY: T-30A4WAY, 2POSITION SOLENOIDOPERATED
DIRECTIONAL SPOOL VALVE
TECHNICAL FEATURES
The 4-way, 2-position directional spool valves are direct
acting. They comprise a hex body (3), solenoid with coil
(2), spool (4), and a coil nut (1).
DNB*-XC* (C Spool)
Function: When de-energized, the spool (4) creates a
blocked ow path in all directions. When energized, the
spool (4) creates a bidirectional open ow path from 3 to
2 and 4 to 1.
DNB*-XN* (N Spool)
Function: When de-energized, the spool (4) creates a
bidirectional open ow path from 3 to 2 and 4 to 1. When
energized, the spool (4) creates a bidirectional open ow
path from 3 to 4 and 2 to 1.
DNB*-XE* (E Spool)
Function: When de-energized, the spool (4) creates a
bidirectional open ow path from 3 to 4 and 2 to 1. When
energized, the spool (4) creates a blocked ow path in all
directions.
DNB*-XV* (V Spool)
Function: When de-energized, the spool (4) creates a
bidirectional open ow path from 3 to 4 and 2 to 1. When
energized, the spool (4) creates a bidirectional open ow
path from 3 to 1 and blocks 2 and 4.
DNB*-XD* (D Spool)
Function: When de-energized, the spool (4) creates a
blocked ow path in all directions. When energized, the
spool (4) creates a bidirectional open ow path from 3 to
4 and 2 to 1.
DNB*-XT* (T Spool)
Function: When de-energized, the spool (4) creates a
bidirectional open ow path from 3 to 1 and blocks 2 and
4. When energized, the spool (4) creates a bidirectional
open ow path from 3 to 2 and 4 to 1.

The DNBD 3000-psi (210-bar) valves use the low-power (17-W) coils; the DNBF 5000-psi (350 bar) valves use the high-power (25-
W) coils. Note that all DNB* valves can be used with the hazardous location coils.
Sun cartridges have a base seven-digit part number. Each
of the digits in the sequence has signicance as shown in
the model code explanation below. Available options and
modiers for specic cartridges, manifolds, and valve packages
are shown on the individual product pages and data sheets.
Not all modiers are applicable for every model.

The DNB* family of FLeX valves is based on the new Sun T-30A cavity. Currently, there are six standard
single-cavity, 90-degree line mount manifolds available in a wide range of port sizes for the new T-30A
cavity. More standard manifolds will be introduced soon, including two-cavity and sandwich style
manifolds for this new cavity.
Visit our website to see a complete list of available standard manifolds for the T-30A cavity.
