Directional Spool Valve H-4WEH25G6X/6EG205N9TK4 - Bosch Rexroth R900782553

External supply with internal return keeps the piping effort down to one additional line. The H-4WEH25G6X/6EG205N9TK4 is plumbed that way, is actuated at 205 VDC and switches flow up to 400 l/min.

Benefits

• External pilot supply, internal return, only the X line is added to the mounting pattern.
• Solenoid actuation at 205 VDC, 3-pole (2 + PE) plug to EN 175301-803.
• Flow up to 400 l/min, 350 bar maximum operating pressure in size 25.
• Three switching positions with spool symbol G, four ports, ISO 4401-08-08-0-05 pattern.
• 17.92 kg weight, NBR seals, HL hydraulic fluid, UKCA to SI2016/1091.

Applications

The valve is used on manifolds that already provide a pilot supply port but no separate drain. Pilot oil leaves through the tank channel of the connection pattern, whose back pressure should be checked beforehand. Pilot pressure comes from the external source.
