The Sun Hydraulics SXEAKAV (SXEAKAV) is a direct-acting sequence valve designed to manage the flow to a secondary circuit once the inlet port pressure exceeds the preset valve setting. It features a pressure control mechanism at port 1, which is relative to the pressure at drain port 3, ensuring precise flow management in hydraulic systems. This model is part of a series of interchangeable three-port sequence cartridges, allowing for seamless integration into existing systems with similar flow paths and cavity sizes. The valve requires connection of port 3 to maintain accurate pressure reference in the control chamber; failure to do so may lead to malfunction due to reciprocating seal weepage. The maximum allowable pressure at port 3 is 5000 psi (350 bar), which directly affects the valve setting on a 1:1 ratio basis. The SXEAKAV is suitable for load holding applications and incorporates Sun's floating style construction, minimizing internal part binding from installation torque or machining variations. It boasts a capacity of up to 30 gpm (120 L/min) and operates effectively under pressures up to 5000 psi (350 bar). The typical response time is approximately 2 milliseconds, with maximum valve leakage at reseat limited to 10 drops/minute (0.7 cc/min). Adjustments can be made via an internal hex screw, with four clockwise turns increasing the setting. Installation requires specific torque settings: valve hex size of 1-1/8 inches (28.6 mm) with torque between 45-50 lbf-ft (61-68 Nm), and locknut torque between 80-90 lbf-in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seals for durability and reliability in various hydraulic applications.
