Directional Poppet Valve M-4SH6D3X/420/V - Bosch Rexroth R901521548

In circuits without electrical control a pilot pressure does the switching. This hydraulically actuated size 6 poppet valve works to symbol D, passes up to 40 l/min and is rated for a maximum operating pressure of 420 bar.

Benefits

• Hydraulic actuation, no coil and no wiring required
• Poppet design, tight even after a long standstill under pressure
• Flow 40 l/min, maximum operating pressure 420 bar
• FKM seals instead of NBR
• Four ports, two switching positions, subplate mounting in size 6
• Interface ISO 4401-03-02-0-05, weight 2.34 kg

Technical data

Application

The valve sits in manifolds where a pilot circuit issues the switching commands, for example in hazardous areas that keep electrics away from the valve. The seat holds the load through long breaks. It runs on HL mineral oil.

Manufacturer

The material number is R901521548. Data sheet RE 22340 covers the 2/2, 3/2 and 4/2 directional seat valves of this series.
