SUN SXCA-LBN
The SUN SXCA-LBN is a pilot-to-open check valve, commonly referred to as a counterbalance valve. It is designed to control overrunning loads by allowing free flow from the directional valve (port 2) to the load (port 1) while blocking flow from port 1 to port 2. The valve will remain closed, holding the load, until sufficient pilot pressure is applied at port 3 to open the checking element. These screw-in, cartridge-style valves are ideal for motion control applications, providing smooth, stable, and chatter-free operation. The SXCA-LBN fits into the standard Sun T-11A cavity and is part of Sun’s reliable Series 1 family of hydraulic valves.
