This is a normally open, balanced poppet, switching element. When the external vent port is

blocked, the poppet remains in the open position. Venting the external port shifts it to the

closed position, provided there is sufficient pressure at port 3.

TECHNICAL FEATURESTECHNICAL FEATURES

Unique balanced construction provides predictable switching with 5000 psi (350 bar) at port 1 and port 2, with the external drain

port open and a minimum pilot pressure of 300 psi (20 bar).

The external -4 SAE vent port may be directly connected to a pilot switching valve. The pilot valve should have a leakage rate of less

than 10 drops/min (0,7 cc/min). and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal

for this application.

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).

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.
