11004144 - VALVE 2-WAY - CP710-8-B-0-C-080 - DANFOSS
Directional Control Valve, 2-Way, Spool Type, Hydraulic Pilot, External Drain
210 bar [3000 psi] • 40 l/min [11 US gpm]
This is a 2-way, spool type, hydraulically piloted directional control valve with external drain. It is available in normally open or normally closed configurations between ports 2 and 3 that shift when pilot pressure is applied to port 1. Due to the external drain, the pilot pressure required shift the valve is dependent on the pressure in port 4, which would normally be connected to tank. 
850168919 - 4 WAY PSV10-34-05-00-00-22-B-00 - DANFOSS
Description: PSV10-34-05-00-00-22-B-00
Function: Proportional Directional Valve, 4-way, 3-position, Spool Type, Non-Compensated
250 bar [3600 psi] • 221/min [S.8 US gpm] 
This is a 4-way, 3-position, spool type, non-compensated proportional directional valve. In its de-energized condition, port 3 is blocked, while ports 2 and 4 are open to port 1. Increasing the current to the bottom coil will cause the spool to move, proportionally opening flow from port 3 to 2 with return flow passing from port 4 to 1. Increasing the current to the top coil will proportionally open flow from port 3 to 4 with return flow passing from port 2 to 1. Using this as a variable orifice in conjunction with a compensator, the valve will provide compensated flow to an actuator in both directions.
