Sunstar Hydraulics CK6B-T17A-XCN Directional Control Valve

Sunstar Hydraulics CK6B-T17A-XCN is a line-mount, externally pilot-operated cartridge valve in the CK6B family, configured around a T17A cavity for direct integration into hydraulic manifolds. It is rated for up to 240 L/min, making it suitable for medium-to-high flow circuits. The XCN suffix identifies an external pilot port, enabling a pilot signal to actuate the valve’s check function; the unit is described as a vented, pilot-to-open check valve with external pilot port. In operation, the external pilot pressure opens the check path to permit controlled flow in the desired direction and then reseats when pilot pressure is removed. This arrangement supports circuits that require a controlled one-way flow under separate pilot control, such as sequencing, load-holding, or controlled release tasks in machinery. The T17A cavity specification defines the standard mounting geometry and cartridge interface, ensuring compatibility with Sunstar CK6B components and with manifolds designed for T17A cavities.
