Directional Poppet Valve M-4SMM6D3X/420/P - Bosch Rexroth R901500644

A manually switched hydraulic circuit needs neither supply voltage nor wiring. The directly actuated directional poppet valve M-4SMM6D3X/420/P covers that case in size 6, carries up to 40 l/min across 4 ports and is rated for a maximum operating pressure of 420 bar.

Benefits

• Maximum operating pressure 420 bar in size 6
• Seat valve design, rated by the manufacturer for safe switching even after longer standstill periods under pressure
• Manual actuation without supply voltage, which is why the supply voltage figure reads -
• 2 switching positions on symbol D across 4 ports at 40 l/min
• 1.99 kg weight, NBR seals matched to HL hydraulic fluid
• Subplate mounting to connection diagram ISO 4401-03-02-0-05

Technical data

Application

Manually actuated seat valves switch clamping circuits, test rigs and service lines on and off wherever no solenoid can or should be driven. The 420 bar rating allows use in high pressure circuits such as clamping cylinders and tool locking. At 1.99 kg and with the ISO 4401-03-02-0-05 hole pattern, the valve sits on common size 6 subplates.
