Introduction
The P120 Monoblock Valve 120 Liters per Minute 250 bar is a monoblock directional valve. It is rated at a nominal flow of 120 L/min (31.7 US gpm) and a maximum pressure of 250 bar (3600 psi). The structure type is monoblock, available in 1, 2, 3, or 4 sections. The operating viscosity range is 15 to 75 mm²/s (15 cSt to 75 cSt). The ambient temperature range is -40°C to +80°C (-40°F to +176°F). The drawing shows dimensions including an overall length of 212 mm, a width of 90 mm, and a height of 324 mm. Port threads include G1, G3/4, and M12. The hydraulic schematic shows a manual control configuration with P, T, A1, B1 work ports and a relief valve symbol.

Design Notes
The P120 has a body made from a single casting. That is what sets it apart from a sectional valve, which is put together from a stack of separate sections. The one-piece design keeps the valve compact and rigid, and it also cuts down on the number of external sealing points. It tends to be the right choice when the circuit count is fixed and there is not much room to work with.
Application Scenarios
The P120 fits hydraulic systems where the pump delivers roughly 120 L/min and the working pressure stays at or below 250 bar (3600 psi). It is designed for machines with a fixed number of hydraulic functions, typically between one and four sections. Manual control is used, so the operator needs to be within reach of the valve. Because the body is compact, it works well in installations where space is limited. The valve runs on mineral oil based hydraulic oil with a viscosity between 15 and 75 cSt, and it can operate in ambient temperatures from -40°C to +80°C (-40°F to +176°F).
If the machine may need additional hydraulic circuits later, or if the pump output is consistently higher than 120 L/min, a sectional valve is a more suitable choice. For those cases, consider the DCV140 Hydraulic Directional Valve 140 Liters per Minute 350 bar or the DCV100 Hydraulic Directional Valve 100 Liters per Minute 350 bar.
Selection Boundaries
If your pump delivers around 120 L/min and your working pressure stays at or below 250 bar, the P120 Monoblock Valve 120 Liters per Minute 250 bar will fit your system. It is a solid choice for machines with a fixed set of hydraulic functions, especially when you want a compact body and manual control.
You would not want this valve if your pump output is consistently above 120 L/min, if your working pressure goes over 250 bar, or if you might need to add more circuits down the road.

FAQ
Q: What is the difference between a monoblock valve and a sectional valve?
A: A monoblock valve has a single cast body. A sectional valve is assembled from stacked sections. The P120 uses a monoblock body, which makes it compact and rigid with fewer external sealing points. However, individual sections cannot be added or replaced after production.
Q: Can I add more sections to the P120 after purchase?
A: No. The number of sections is fixed at the time of order. The P120 is available in 1, 2, 3, or 4 sections. If you may need additional circuits in the future, a sectional valve is a more suitable choice.
Q: How do I determine the correct number of sections for my application?
A: Count the number of independent hydraulic functions on your machine. The P120 supports up to 4 sections. Each section controls one working circuit.
Q: What is the purpose of the relief valve symbol in the hydraulic schematic?
A: The schematic includes a relief valve symbol, which indicates a pressure-limiting function in the circuit. This helps protect the system from overpressure.
Q: What is the warranty and delivery time?
A: The warranty is 12 months against B/L date. Standard delivery time is 10–14 business days for items not in stock, and 2–3 business days if stock is available.
