The Sun Hydraulics SXCALEV (SXCALEV) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This model controls the pressure at port 1 relative to the drain port 3, and all three-port sequence cartridges are interchangeable, sharing the same flow path and cavity for a given frame size. While it is a zero pilot flow valve, maintaining an open connection at port 3 is crucial for proper operation, as blocking it can lead to malfunction due to reciprocating seal weepage. The pressure at port 3 adds directly to the valve setting in a 1:1 ratio and should not surpass 5000 psi (350 bar). The SXCALEV is suitable for load-holding applications and can be used in corrosive environments when specified with corrosion-resistant components, indicated by model code suffixes AP or LH. This valve features Sun's floating style construction to minimize binding risks due to excessive installation torque or machining variations. It operates within a maximum capacity of 15 gpm (60 L/min) and maintains pressures up to 5000 psi (350 bar). The typical response time is approximately 2 ms with minimal leakage upon reseat, limited to 10 drops/min (0.7 cc/min). Adjustment settings are increased by turning clockwise up to four turns, with specific installation torque requirements: valve hex size of 7/8 inch (22.2 mm), installation torque between 30 - 35 lbf ft (41 - 47 Nm), adjustment screw internal hex size of 5/32 inch (4 mm), locknut hex size of 9/16 inch (15 mm), and locknut torque of 80 - 90 lbf in (9 -10 Nm). The cartridge's weight is approximately .30 lb (.15 kg) and uses a Viton seal kit part number: 990011006.
