The Sun Hydraulics SCCACWN (SCCACWN) is a direct-acting sequence valve with an integrated reverse flow check feature. This valve is designed to supply a secondary circuit with flow once the inlet port pressure exceeds the pre-set threshold. It incorporates an integral check valve allowing reverse flow from port 2 to port 1, making it suitable for load holding applications. The sequence valve controls pressure at port 1 relative to the drain port 3, and it is crucial that port 3 remains connected to maintain proper functionality; blocking it can lead to malfunction due to seal weepage. The pressure at port 3 should not exceed 5000 psi (350 bar) as it adds directly to the valve setting in a 1:1 ratio. This product features Sun's floating style construction, which minimizes potential internal part binding caused by excessive installation torque or cavity machining variations. The SCCACWN model is physically and functionally interchangeable with other three-port sequence cartridges of the same frame size, offering flexibility in application. It supports EPDM seals for use with phosphate ester fluids but cautions against exposure to petroleum-based substances which could damage the seals. The valve has a capacity of up to 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It exhibits a typical response time of approximately 2 milliseconds, with maximum leakage at reseat limited to 10 drops per minute (0.7 cc/min). Installation specifications include a hex size of 7/8 inch (22.2 mm) and torque requirements between 30\u201335 lbf\u00b7ft (41\u201347 Nm). This model weighs approximately .30 lb (.15 kg), ensuring ease of integration into various hydraulic systems.

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.
