The Sun Hydraulics SXEAKWN (SXEAKWN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure surpasses the valve setting. This valve manages pressure at port 1 relative to the drain port 3, ensuring precise control in various applications. All three-port sequence cartridges are interchangeable, maintaining the same flow path and cavity for a given frame size. It's crucial to connect port 3 to maintain a pressure reference in the control chamber, as blocking it can lead to malfunction due to reciprocating seal weepage. The pressure at port 3 directly adds to the valve setting at a 1:1 ratio and must not exceed 5000 psi (350 bar). This model is suitable for load-holding applications and features Sun's floating style construction, which minimizes internal part binding from excessive installation torque or machining variations. With a capacity of 30 gpm (120 L/min) and maximum operating pressure of 5000 psi (350 bar), it offers quick response times typically around 2 ms. The valve's leakage at reseat is minimal, with a maximum of 10 drops/minute (0.7 cc/min). The adjustment mechanism allows for four clockwise turns to increase settings, ensuring flexibility in operation. The SXEAKWN has specific installation requirements: a valve hex size of 1-1/8 inches (28.6 mm), installation torque ranging from 45-50 lbf-ft (61-68 Nm), an adjustment screw internal hex size of 5/32 inches (4 mm), and locknut torque between 80-90 lbf-in (9-10 Nm). Weighing .60 lb (.30 kg), this model includes a Viton seal kit under cartridge number 990202006, providing robust sealing performance for demanding environments.
