The Sun Hydraulics SCEACCV (Material Number: SCEACCV) is a direct-acting sequence valve with an integral reverse flow check, designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This model includes a built-in check valve that allows reverse flow from port 2 to port 1, making it suitable for load-holding applications. The pressure setting controls the pressure at port 1 relative to the drain port 3, which must be connected to maintain proper function. This zero pilot flow valve requires careful management of pressure at port 3, as it is directly additive to the valve setting and should not exceed 5000 psi (350 bar). The SCEACCV features Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It supports a maximum operating pressure of 5000 psi and has a capacity of 30 gpm (120 L/min), with typical response times around 2 ms. The valve incorporates interchangeable design elements for ease of integration into existing systems, sharing cavity and flow path characteristics with other three-port sequence cartridges within its frame size. Additionally, it offers precise adjustment capabilities via a screw mechanism; clockwise turns increase settings, while specific hex sizes are provided for installation and adjustment tasks. The unit weighs approximately .60 lb (.30 kg) and comes with Viton seal options for enhanced durability in demanding environments.
