The Sun Hydraulics SCCALAN is a high-performance, pilot-operated, balanced poppet logic element. This cartridge valve is designed as a normally open component, allowing flow from port 1 to port 2 until pilot pressure is applied at port 3. Its balanced poppet design ensures minimal effect from back-pressure at port 2, providing stable and reliable operation across a wide range of hydraulic applications. Manufactured for the standard Sun T-11A cavity, the SCCALAN is a versatile solution for functions such as blocking, load-holding, and directional control within complex hydraulic circuits.
