Product description
Bosch Rexroth 4WE6HA6X/EG24N9K4 is a size 6, 4/2-way directional spool valve in the WE 6 range and component series 6X. Material number R900549534 identifies the version with spool symbol HA, a direct-acting wet-pin solenoid and spring return. In its initial position, the HA spool symbol connects all four ports P, T, A and B. The electrical actuation uses 24 V DC with a voltage tolerance of ±10 percent. The solenoid has a rated power of 30 W and is specified for continuous duty. Individual connection K4 uses a three-pole device connector with two contacts plus protective earth according to DIN EN 175301-803. The standard hydraulic version is rated up to 350 bar at ports P, A and B; up to 210 bar applies at tank port T with DC voltage. Maximum flow is 80 l/min. The porting pattern corresponds to ISO 4401-03-02-0-05 and CETOP D03. NBR is specified as the seal material. Listed hydraulic fluids are HL, HLP, HLPD, HVLP, HVLPD and HFC. The version with one solenoid weighs 1.45 kg. The drawing for the unchanged installation geometry of component series 6X gives approximate dimensions of 145.7 × 69 × 45 mm. Type code, material number, spool symbol, solenoid voltage and connector format together identify this valve version.
