The Sun Hydraulics SCCAKWV (Material Number: SCCAKWV) is a direct-acting sequence valve with a reverse flow check feature designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This valve includes an integral check valve that allows reverse flow from port 2 sequence to port 1 inlet. It is crucial for the pressure at port 3, which acts as a drain, to be connected to maintain a proper pressure reference in the control chamber; blocking this port can lead to malfunction due to seal weepage. The pressure at port 3 directly adds to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The SCCAKWV is suitable for load-holding applications and features interchangeable cartridges across all three-port sequence configurations, maintaining consistent flow paths and cavity compatibility for given frame sizes. This model is available with EPDM seals, making it compatible with systems using phosphate ester fluids but unsuitable for petroleum-based fluids. For use in corrosive environments, corrosion-resistant variants are available, identifiable by model code suffixes AP or LH, indicating stainless steel or zinc-nickel plated components respectively. The floating style construction of the cartridge minimizes internal binding risks due to installation torque or machining variations. Technical specifications include a capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. The valve features an adjustment mechanism allowing up to five clockwise turns to increase settings, with specific torque guidelines for installation and locknut adjustments. Weighing approximately .30 lb (.15 kg), this model's design ensures efficient operation in demanding hydraulic applications.

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.
