The Sun Hydraulics SXCALAN (SXCALAN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve setting. The pressure setting regulates the pressure at port 1 relative to port 3, which serves as a drain. Notably, this zero pilot flow valve requires port 3 to be connected to maintain a pressure reference in the control chamber; blockage can cause malfunctions due to seal weepage. Pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The valve is suitable for load-holding applications and features corrosion-resistant options with external stainless steel or zinc-nickel plating. Its floating style construction minimizes internal part binding from excessive installation torque or machining variations. The SXCALAN fits into T-11A cavities and belongs to Series 1, offering a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 2 in\u00b3/min (30 cc/min), with a maximum operating pressure of up to 5000 psi (350 bar). Typical response time for this model is around 2 milliseconds, and it exhibits maximum leakage of about 10 drops/min (0.7 cc/min) upon reseat. For adjustments, turning clockwise increases the setting across four full turns, with specific torques required for installation and locknuts. The cartridge weighs approximately .30 lb (.15 kg), and it uses Viton seals identified by part number 990011006.
