This manual lever-operated monoblock directional control valve is built for compact, straightforward hydraulic circuits that require reliable on/off or directional control of one actuator. With a rated flow of 160 L/min and maximum pressure up to 315 bar, it supports demanding mobile equipment functions such as lift/lower, tilt, auxiliary attachment control, and other single-circuit operations.
Key advantages:
- Monoblock structure: compact layout for easier installation in tight machine spaces.
- High capacity: suitable for higher flow mobile systems (160 L/min).
- High pressure capability: up to 315 bar for heavy-duty applications.
- Broad fluid compatibility: operating viscosity range 12–400 mm²/s for varied hydraulic oils and working conditions.
- Wide environmental adaptability: ambient temperature range from -40°C to +80°C for cold starts and hot climates.
