Hydraulic Monoblock Valve FM55/4 1/2 4P DDSS
Product description:
The FM55/4 1/2 4P DDSS is a four-section, high-flow hydraulic monoblock directional control valve that provides two DE (double effect) – double-acting – and two SE (single effect) – single-acting – working circuits. All control levers feature a spring return mechanism, ensuring each section immediately returns to a safe neutral position when released.
The valve is built on the high-performance FM55 platform, offering a 50 l/min nominal and up to 70 l/min maximum flow rate, and can operate at pressures up to 300 bar. The integrated pressure relief valve is adjustable between 100–250 bar, with a factory setting of 140 bar. The 1/2" BSP ports ensure high flow capacity with minimal pressure loss.
Technical specifications:
- Nominal flow rate: 50 l/min
- Maximum flow rate: 70 l/min
- Nominal pressure: 280 bar
- Maximum operating pressure: 300 bar
- Max. tank line pressure: 80 bar
- Relief valve setting range: 100–250 bar (factory: 140 bar)
- Number of sections: 4
- Spool type: DDSS – two double-acting and two single-acting circuits
- Inlet/outlet ports: 1/2" BSP
Applications:
- Simultaneous control of two DE and two SE hydraulic circuits
- Tipping, lifting and manipulator systems
- Agricultural and industrial hydraulic machinery
- High-flow multi-circuit hydraulic applications
The FM55/4 1/2 4P DDSS valve is an excellent choice for systems where mixed-function hydraulic circuits must be reliably and powerfully controlled within a compact monoblock valve assembly.
