The Sun Hydraulics SCGALAV (Material Number: SCGALAV) is a direct-acting sequence valve with an integrated reverse flow check feature, designed to regulate secondary circuit flow once the inlet port pressure surpasses the valve setting. This model includes an integral check valve that facilitates reverse flow from port 2 to port 1. The valve's pressure setting manages the pressure at port 1 relative to the drain port 3, and it is crucial that port 3 remains unblocked for proper functionality. The sequence cartridge is interchangeable across all three ports, maintaining consistency in flow path and cavity dimensions for a given frame size. It is optimized for load-holding applications and features Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a capacity of 60 gpm (240 L/min), and a typical response time of 2 ms. The valve exhibits minimal leakage at reseat, with a maximum rate of 10 drops/min (0.7 cc/min). It has an adjustment range with five full clockwise turns required to increase the setting, utilizing an internal hex adjustment screw size of 5/32 inches (4 mm). Installation requires a torque of 150-160 lbf ft (203-217 Nm), and it weighs approximately 1.50 lb (0.70 kg). The SCGALAV is equipped with Viton seals for durability, making it suitable for various hydraulic applications requiring precise pressure control and reliable performance under demanding conditions.

Direct-acting sequence valves with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Suitable for use in load holding applications.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
