The Sun Hydraulics SCCACWE (Material Number: SCCACWE) is a direct-acting sequence valve with an integral reverse flow check, designed to provide flow to a secondary circuit once the inlet pressure at port 1 exceeds the valve's setting. This valve is equipped with a check valve that allows reverse flow from port 2 back to port 1. It is essential for the drain port 3 to be connected to maintain a pressure reference, as blocking it can cause malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). This sequence valve is ideal for load holding applications and features interchangeability in all three-port sequence cartridges, ensuring consistent flow paths and cavity compatibility within a given frame size. The SCCACWE model incorporates Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. It can handle capacities up to 15 gpm (60 L/min) with maximum operating pressures of 5000 psi (350 bar). The response time of this valve is typically around 2 ms, and it has a maximum leakage rate of 10 drops/min at reseat. The check cracking pressure is set at 40 psi (2.8 bar), and adjustments can be made with five clockwise turns using an internal hex screw. The cartridge comes with Viton seals, but options are available for EPDM seals suitable for phosphate ester fluids, ensuring compatibility across different hydraulic systems. Corrosion-resistant options are available for use in harsh environments, identified by suffixes AP or LH in the model code. The valve's compact design features a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30-35 lbf ft (41-47 Nm).

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).
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- 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.
