What Makes This Valve Different
The P120 is a monoblock valve - one solid piece of iron, not sections bolted together. No through-bolts to torque, no seals between sections because there are no sections.
120 L/min at 250 bar inlet, 300 bar at the work ports. Available with 1 to 4 levers.
Most valves have the same pressure rating on the inlet and work ports. The P120 is different - the work ports handle 300 bar while the inlet is 250 bar. That means your cylinders can get more pressure than the pump delivers. If you need high force at the actuator, this matters.
It's a monoblock, so what you order is what you get. No adding sections later. But for equipment with fixed functions - and a lot of medium to large equipment fits that description - monoblock makes more sense than paying for sectional flexibility you'll never use.
For equipment that needs 120 L/min and up to four functions, the 1-4P120 Hydraulic Valve One-Four Levers is a straightforward choice.
A Closer Look
120 L/min - Medium to Large Equipment Territory
120 L/min is enough for telehandlers, larger forklifts, compact wheel loaders, and agricultural machinery. Not 40, not 80 - 120. The kind of flow that sits in the middle, where a lot of equipment actually lives.
Dual Pressure Rating - Higher Work Port Pressure
Here's what sets the P120 apart: P port is 250 bar, but A and B ports are 300 bar. Most valves don't do this. It means your cylinders can get more pressure than the pump inlet - useful when you need high force at the actuator but the pump doesn't need to run at that pressure.
Monoblock Simplicity
One casting. No stack assembly. No section-to-section alignment issues. The spool bores are all machined into the same block, so they stay aligned for the life of the valve. No through-bolts to check. No section seals to leak.
Spool Return Options
Two choices: spring-centered (lever returns to neutral when released) or detent (lever stays where you put it). One for momentary operation, one for hold. Choose what fits your machine.
Integral Relief Valve
Built-in. Protects the system from overpressure. One less thing to add externally.
Applications:
Based on its flow rating and monoblock construction, the 1-4P120 Hydraulic Valve One-Four Levers typically ends up on:
Telehandlers
Boom lift, extension, and attachment functions. The 120 L/min flow matches the pump output of medium to large telehandlers.
Forklifts and Pallet Stackers
Mast tilt and lift functions. The 120 L/min moves the mast faster than 80 L/min - matters in busy warehouses where every second counts.
Compact Wheel Loaders
Boom and bucket functions. Operators notice the difference when stacking material - the boom comes up without that lag they'd gotten used to.
Tractors with Front Loaders
Loader lift and bucket tilt. Farm work is seasonal - you run hard when the weather holds, and you don't stop for breakdowns. The P120 holds up to long days.
Skid-Steer Loaders and Backhoes
Boom, bucket, and auxiliary attachments. The 120 L/min flow keeps everything responsive, even when running multiple functions at once.

FAQ
Q: Are there any special precautions during installation?
A: Before installation, inspect the valve body for shipping damage and thoroughly clean the piping. Tighten the mounting bolts in a diagonal pattern, applying torque in stages to the specified value; avoid overtightening on one side, which could cause valve body deformation or valve core binding. Ensure the mounting surface has a flatness of at least 0.5 mm so that the valve body is not subjected to extraneous stress. Prior to initial startup, operate the system at low pressure to purge any trapped air.
Q: How do I confirm specifications and model numbers when purchasing?
A: You need to confirm the following information: number of sections, control method, spool neutral function type, main relief valve setting pressure, presence of overload or make-up valves, port thread specifications, and mounting dimensions. It is recommended to send the technical requirements and installation drawings to the sales team for verification.
Q: What kind of equipment is the P120 suitable for?
A: The P120 is primarily used in equipment such as telehandlers, forklifts, all-terrain cranes, medium and small excavators, skid-steer loaders, compact wheel loaders, dump trucks, concrete pump trucks, harvesters, and tractors equipped with front loaders.
Q: What precautions should be taken during prolonged periods of inactivity?
A: Before the equipment is stored for an extended period, apply anti-rust oil to the valve core to prevent corrosion. Before putting it back into service, check that the valve core moves freely and bleed out any air before normal operation.
Q: Why has the P120 slowed down after operating for some time?
A: First, check whether the oil pump is supplying oil correctly, whether the relief valve's pressure setting has dropped, and whether the oil temperature is too high (causing a drop in viscosity). If these factors are not the cause, the issue may be increased internal leakage due to spool wear.
