The Sun Hydraulics SCEALCN (SCEALCN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve's set threshold. It features an integral check valve that enables reverse flow from port 2 to port 1. The sequence valve's pressure setting governs the pressure at port 1 concerning the drain port 3, which must be connected to maintain a proper pressure reference in the control chamber. Blocking port 3 can lead to valve malfunction due to reciprocating seal weepage. The valve allows for a maximum operating pressure of 5000 psi (350 bar), with pressure at port 3 being directly additive to the valve setting at a 1:1 ratio, not exceeding this limit. This product is suitable for load holding applications and offers interchangeable functionality and physical compatibility within its series, ensuring consistent flow paths and cavity dimensions across similar frame sizes. The design incorporates Sun's floating style construction, reducing the likelihood of internal parts binding due to excessive installation torque or cavity-cartridge machining variations. It has a capacity of handling up to 30 gpm (120 L/min) with factory pressure settings established at 2 in/min (30 cc/min). Typical response time is approximately 2 ms, and maximum valve leakage upon reseat is limited to 10 drops/min (0.7 cc/min). The check cracking pressure is set at 25 psi (1.7 bar). Adjustment can be made through clockwise turns, and it includes specific hex sizes for installation and adjustment components, ensuring precision during setup. The model weighs approximately .60 lb (.30 kg) and comes with a Viton seal kit option for enhanced durability in various applications.

Direct-acting sequence valves with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
- Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Suitable for use in load holding applications.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- 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.
