The Sun Hydraulics SCCAKBN (SCCAKBN) is a direct-acting sequence valve designed to manage flow and pressure in hydraulic systems effectively. This model is equipped with a reverse-flow check valve, allowing it to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. The integral check valve facilitates reverse flow from port 2 to port 1, enhancing system flexibility. Notably, the pressure setting of this sequence valve controls the pressure at port 1 relative to the drain port 3, which must be connected to maintain proper functionality. The maximum allowable pressure at port 3 is 5000 psi (350 bar), and it directly adds to the valve setting at a 1:1 ratio. This zero pilot flow valve is suitable for load-holding applications and features interchangeable cartridges across all three-port sequence models, ensuring compatibility within similar frame sizes. The SCCAKBN model incorporates Sun's floating style construction, minimizing potential internal binding due to installation torque or machining variations. It supports a capacity of up to 15 gpm (60 L/min) and operates efficiently under a maximum pressure of 5000 psi (350 bar). The typical response time is around 2 ms, with minimal leakage at reseat. For versatility in fluid compatibility, cartridges configured with EPDM seals are available for phosphate ester fluid systems; however, these should not be exposed to petroleum-based substances. Corrosion-resistant options are also offered with specific model code suffixes indicating external stainless steel or zinc-nickel plated components. Installation specifications include a hex size of 7/8 inch (22.2 mm) and an installation torque range of 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.
