The Sun Hydraulics SXCALCV (Material Number: SXCALCV) is a direct-acting sequence valve designed for hydraulic systems requiring precise control of pressure and flow. This valve activates a secondary circuit once the inlet port 1 pressure surpasses the preset threshold, maintaining control by referencing the pressure at drain port 3. All three-port sequence cartridges are interchangeable, ensuring compatibility within the same frame size. Notably, this zero pilot flow valve necessitates an open connection at port 3 to prevent malfunction due to seal weepage, with pressures not exceeding 5000 psi (350 bar). The valve is ideal for load-holding applications and features corrosion-resistant options identified by specific model code suffixes for use in harsh environments. It incorporates Sun's floating style construction to mitigate binding issues from installation torque or machining variations. The SXCALCV operates within a cavity T-11A and has a series 1 capacity of 15 gpm (60 L/min). Factory pressure settings are established at 2 in/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar) and typical response time of 2 ms. Valve leakage is minimal, with a maximum of ten drops per minute at reseat. The adjustment mechanism allows for pressure setting changes by turning clockwise up to four turns. Installation requires specific torques: valve hex size is 7/8 in. (22.2 mm), with an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw uses an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm) with a torque requirement of 80-90 lbf in. (9-10 Nm). The model weighs .30 lb (.15 kg) and includes a Viton seal kit option under cartridge number 990011006 for enhanced durability and performance in various applications.
