The Sun Hydraulics SCEACEV (SCEACEV) is a direct-acting sequence valve with a reverse flow check designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. Featuring an integral check valve, it allows reverse flow from port 2 to port 1. The valve's pressure setting controls the pressure at port 1 relative to the drain port 3, which must be connected to maintain proper function, as blocking it can cause malfunction due to seal weepage. The sequence valve is suitable for load-holding applications and offers physical and functional interchangeability across all three-port sequence cartridges of a given frame size. It incorporates Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations. The SCEACEV has a cavity T-2A Series 2 design with a capacity of 30 gpm (120 L/min). It operates at a maximum pressure of 5000 psi (350 bar) and features typical response times of around 2 ms. Maximum leakage at reseat is limited to 10 drops/min (0.7 cc/min), and it has a check cracking pressure of 25 psi (1.7 bar). The adjustment mechanism allows for up to five clockwise turns to increase the setting, with specific hex sizes and torque specifications provided for installation and adjustment. Weighing approximately 0.60 lb (0.30 kg), it uses Viton seals, with seal kit part number 990202006 available for maintenance needs.

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.
