While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics SCCACBN (SCCACBN) is a direct-acting sequence valve with an integrated reverse flow check, designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. The valve features an integral check valve for reverse flow from port 2 to port 1 and requires connection to port 3 drain to maintain proper pressure reference in the control chamber. The pressure at port 3 adds directly to the valve setting at a 1:1 ratio, with a maximum of 5000 psi (350 bar). This makes it suitable for load holding applications. The cartridge is interchangeable with other 3-port sequence cartridges of the same frame size, maintaining consistent flow paths and cavity requirements. It incorporates EPDM seals for compatibility with phosphate ester fluids, while exposure to petroleum-based fluids can damage these seals. Corrosion-resistant options are available, identified by model code suffixes AP or LH for stainless steel or zinc-nickel plated components, respectively. The floating style construction minimizes internal binding due to installation torque or machining variations. The SCCACBN has a capacity of 15 gpm (60 L/min) and operates at pressures up to 5000 psi (350 bar), with typical response times of 2 ms and maximum leakage rates at reseat of 10 drops/min (0.7 cc/min). It features adjustable settings through clockwise turns, with specific torque requirements for installation and adjustment components. The cartridge weighs .30 lb (0.15 kg) and uses Viton seal kits for maintenance and replacement 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).
- 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.
