MODEL
DODP
Normally open, balanced poppet, logic element - pressure adjustable
SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-21A
This is a normally open, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet
remains open until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point
the poppet shifts to the closed position.

TECHNICAL FEATURES
Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both port 1 and port 2. When the remote pressure signal at port 3 exceeds
the internal valve setting, the valve shifts to the closed position.
Any backpressure at the drain port is directly additive to the valve setting.
These valves are hydraulically balanced between port 1 and port 2.
Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
Leakage rate between port 1 and port 2 is very low, typically less than 10 drops/min. at 5000 psi (0,7 cc/min at 350 bar).
Valve will open when the pilot pressure falls below 145 psi (10 bar).
All ports will accept 5000 psi (350 bar).

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.
