Product description：

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.
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.
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.
W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
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.

Product features:：

Maximum working pressure = 350 bar;
Maximum oil leakage = RSDC: 32,8 cc/min./70 bar, RSFC: 49,2 cc/min./70 bar, RSHC: 65,5 cc/min./70 bar, RSJC: 81,9 cc/min./70 bar;
Response time =10ms;
The pressure of the oil port 3 directly applied to the set pressure of the valve does not exceed 350 bar;
When the pressure reaches the set value, the guided pressure flow rate of oil port 3(oil discharge) will gradually increase with the pressure of oil port 1(oil intake).
The minimum set pressure of all RSBC springs is 5bar;
