TECHNICAL FEATURES
Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the external drain open and a minimum pilot
pressure of 400 psi (30 bar).
Valve will open when the pilot pressure falls below 145 psi (10 bar).
These valves are hydraulically balanced between port 1 and port 2.
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).
These 3-port balanced logic valves use the same cavity as unbalanced logic valves of the same frame size and can be considered functional replacements.
Available in external atmospheric vent (X control) or static external drain (E control) configurations.
Three-port vented logic elements with the X control are atmospherically referenced and considered problem solvers for existing circuits using non-vented valves.
Over time, these valves will eventually leak externally and/or allow moisture into the spring chamber. Four-port valves are recommended for new applications.
Alternately, the external vent port can be connected to drain if the static drain port option (control option E) is selected. Removing the vent plug will convert an X
control to an E control.
Port 1 and port 2 are fully sealed from port 3.
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.
