The Sun DTDAMCN is a high-performance, pilot-assisted counterbalance valve with an integral check valve. Designed as a screw-in hydraulic cartridge valve, it is engineered to control overrunning loads and provide reliable load holding. The pilot-assist feature allows the valve to open and permit flow from port 1 to port 2 when sufficient pilot pressure is applied at port 3. The integral check valve allows free flow from port 2 to port 1. The DTDAMCN is ideal for applications requiring smooth and stable motion control, thermal expansion relief, and protection against hydraulic line failure. Its robust construction ensures durability and consistent performance in demanding hydraulic systems.
