DRBB
2-way, direct-acting, directional valve with internal drain to port 3 - normally
closed
SERIES 1 / CAPACITY: 28 L/min. / CAVITY: T-11A
NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
Normally closed, direct-acting, 2-way directional cartridges are switching devices typically used in moderate flow
circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic
cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the setting.

TECHNICAL FEATURES
Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration,
the 4 port version of this valve may be a solution.
Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
This valve is not bistable; it is capable of modulating between the two positions shown.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
