The Sun Hydraulics SXCALBN (SXCALBN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This valve controls pressure at port 1 relative to the drain port 3, making it suitable for load holding applications. It features a zero pilot flow design but requires port 3 to be connected to maintain pressure reference in the control chamber. Blocking port 3 can cause malfunction due to reciprocating seal weepage. The valve setting is directly additive with pressure at port 3 at a 1:1 ratio, with a maximum of 5000 psi (350 bar). The SXCALBN model incorporates Sun's floating style construction, reducing the risk of internal binding from excessive torque or machining variations. It fits into cavity T-11A and has a series capacity of 15 gpm (60 L/min). Factory pressure settings are established at 2 in\u00b3/min (30 cc/min), and it operates up to a maximum pressure of 5000 psi (350 bar). Typical response time is approximately 2 ms, with maximum valve leakage at reseat being 10 drops/min (0.7 cc/min). Adjustment for increasing settings requires approximately four clockwise turns. The valve's hex size is 7/8 inch (22.2 mm), with an installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), and the locknut hex size is 9/16 inch (15 mm) with a torque range of 80-90 lbf in (9-10 Nm). Weighing approximately .30 lb (.15 kg), it uses Viton seals for its cartridge, identified by seal kit number: 990011006.
