REXROTH 4WE 10 HA33/CW230N9K4/V R900973907

Rexroth Hydraulic Directional Control Valve NG10

Description

This is a 4/3-way directional spool valve, model 4WE 10 HA33/CW230N9K4/V, from Bosch Rexroth. It is a direct-operated valve with solenoid actuation, designed for reliable performance in industrial hydraulic systems. This particular model operates on 230V AC and features a spring-centered spool with the ‘HA’ configuration, which connects ports P to T in the neutral position. The NG10 size (CETOP 5) ensures standard mounting compatibility.

FAQ

What do the designations in ‘4WE 10 HA33/CW230N9K4/V’ mean?

This code specifies the valve’s function: 4WE = 4-way directional valve, 10 = nominal size NG10, HA = spool type (spring-centered, P to T in center position), 33/ = component series, CW230 = 230V AC solenoid type, N9 = with concealed manual override, K4 = electrical connector type, V = FKM seals.

Can I use a different voltage solenoid coil with this valve body?

Yes, the solenoid coil (part no. R900071037) can be replaced. You can mount a different coil from the same Rexroth series with a different voltage (e.g., 24V DC) as long as it is compatible with the valve stem and provides the required actuation force. Always check the datasheet for compatible coil part numbers.

What is the maximum operating pressure for this valve?

According to the datasheet for the 4WE 10 … /3X series, the maximum operating pressure for ports P, A, and B is 315 bar (4568 PSI), and for port T (the return line), it is 160 bar (2320 PSI). Always verify this against your specific application’s requirements.
