Pilot operated, balanced piston sequence valve
CAPACITY: 30 L/min. / CAVITY: T-163A
Pilot-operated, balanced piston sequence valves will supply a secondary circuit with flow once the pressure at the
inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port
1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence),
up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in
the return line.

TECHNICAL FEATURES
All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
The main stage orifice is protected by a 150 micron stainless steel screen.
Minimum setting is 75 psi (5 bar) for all spring ranges.

Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
Not suitable for use in load holding applications due to spool leakage.
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.
