The Sun Hydraulics SCCACCV (SCCACCV) is a direct-acting sequence valve with a reverse flow check, designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. It features an integral check valve allowing reverse flow from port 2 to port 1. The valve controls the pressure at port 1 relative to the drain port 3, and while it is a zero pilot flow valve, maintaining a connection to port 3 is essential for proper function. The pressure at port 3 directly adds to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). This model is suitable for load-holding applications and offers interchangeability across all three-port sequence cartridges of the same frame size. It can be configured with EPDM seals for phosphate ester fluids, but these seals are incompatible with petroleum-based substances. Corrosion-resistant options are available, identified by suffixes AP or LH for stainless steel or zinc-nickel plated components, respectively. The Sun floating style construction reduces binding risks from excessive torque or machining variations. Specifications include a capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 2 ms, and maximum leakage at reseat of 10 drops/min (0.7 cc/min). The check cracking pressure is set at 40 psi (2.8 bar), with adjustment requiring up to five clockwise turns to increase settings. It has specific installation requirements including torque settings and seal kit options like Viton: 990011006, ensuring reliable performance in varied conditions.

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.
