The Sun Hydraulics SXCAKEV (SXCAKEV) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This valve controls the pressure at port 1 relative to the drain port 3, making it suitable for load-holding applications. Notably, all three-port sequence cartridges are interchangeable, maintaining the same flow path and cavity for a given frame size. Despite being a zero pilot flow valve, it requires port 3 to be connected to maintain pressure reference in the control chamber; blocking this port can lead to malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The cartridge is corrosion-resistant, with options for stainless steel or zinc-nickel plated components. It incorporates Sun's floating style construction to prevent internal part binding from excessive installation torque or machining variations. The SXCAKEV features a T-11A cavity, Series 1 capacity of up to 15 gpm (60 L/min), and operates under maximum pressures of 5000 psi (350 bar). It has a typical response time of 2 ms and maximum leakage of 10 drops/min at reseat conditions. Adjustments can be made via an internal hex screw with specific torque requirements for installation and locknut adjustments. The model weighs .30 lb (.15 kg) and is compatible with Viton seal kits (990011006). This sequence valve opens when inlet pressure exceeds its setting, allowing bidirectional flow as long as port 1 remains above this threshold.
