The Sun Hydraulics SXEALCV (SXEALCV) is a direct-acting sequence valve designed to manage the flow to a secondary circuit once the pressure at the inlet port 1 surpasses the set threshold. This valve ensures precise control of pressure at port 1 relative to the drain port 3, with all three-port sequence cartridges being interchangeable in terms of flow path and cavity for a given frame size. The SXEALCV features zero pilot flow, but requires port 3 to be connected for maintaining a pressure reference in the control chamber; blocking this port can lead to malfunction due to seal weepage. The valve setting pressure is directly influenced by the pressure at port 3, with an additive effect at a 1:1 ratio, not exceeding 5000 psi (350 bar). It is particularly suitable for load-holding applications and incorporates Sun's floating style construction, which minimizes internal part binding due to excessive installation torque or machining variations. The SXEALCV has a capacity of up to 30 gpm (120 L/min) and operates under a maximum pressure of 5000 psi (350 bar). Its typical response time is approximately 2 ms, with maximum valve leakage at reseat being limited to 10 drops/min (0.7 cc/min). The valve's adjustment can be increased with four clockwise turns, and it features specific installation torque requirements: valve hex size is 1-1/8 in. (28.6 mm), requiring torque between 45-50 lbf ft (61-68 Nm), while locknut hex size is 9/16 in. (15 mm), requiring torque between 80-90 lbf in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seals as part of its construction for enhanced durability and performance reliability.
