Directional Poppet Valve M-4SMM6D3X/420 - Bosch Rexroth R901121178

Hand operated poppet valves come with several designs of actuating element. Directional poppet valve M-4SMM6D3X/420 weighs 1.99 kg in this version, works with spool symbol D across four ports and is released for 420 bar.

Benefits

• 1.99 kg in size 6.
• Manual actuation with no electrical connection and no control line.
• 40 l/min at 420 bar, subplate mounting ISO 4401-03-02-0-05.
• Spool symbol D, two switching positions across four ports.
• Poppet design with NBR seals for HL hydraulic fluid.

Application

Typical uses are manually operated clamping circuits and test rigs. Since the valve needs no solenoid, wiring and heat input in the manifold are avoided. Swapping it for a solenoid operated NG6 version leaves the interface pattern unchanged.
