The Sun Hydraulics SCCACBV (SCCACBV) is a direct-acting sequence valve with an integrated reverse flow check, designed to manage secondary circuit flow once the inlet port pressure surpasses the valve setting. This model features an integral check valve that allows reverse flow from port 2 to port 1, making it suitable for load holding applications. The pressure setting regulates the pressure at port 1 relative to 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 maximum allowable pressure at port 3 is 5000 psi (350 bar), which directly adds to the valve setting in a 1:1 ratio. The SCCACBV supports interchangeable cartridges across all three-port sequence models within the same frame size, ensuring ease of replacement and compatibility. The cartridge is constructed with corrosion-resistant materials, available with options for external stainless steel or zinc-nickel plating for harsh environments. It employs Sun's floating style construction, reducing internal part binding risks due to installation torque or machining variations. With a capacity of 15 gpm (60 L/min) and a factory pressure setting established at 2 in/min (30 cc/min), this model operates under a maximum pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, and leakage at reseat does not exceed 10 drops/min (0.7 cc/min). The valve design includes EPDM seals for phosphate ester fluid systems, but these seals are incompatible with petroleum-based fluids. Installation requires specific torques for various components, ensuring secure and optimal performance in 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.
