P120 Series Hydraulic Monoblock Valve

Shijiazhuang Laiye Import& Export Trading Co., Ltd. is one of the leading manufacturers and suppliers of p120 series hydraulic monoblock valve in China, also supports customized service. If you're going to wholesale high quality p120 series hydraulic monoblock valve made in China, welcome to get pricelist from our factory.

The P120 Series Hydraulic Monoblock Valve flows 120 L/min - the largest in the P series.

If you're running equipment that needs more flow than the P80 can deliver, the P120 is the step up. Telehandlers, forklifts, all-terrain cranes, medium excavators - these machines need 120 L/min to perform.

Monoblock construction. One piece of cast high-strength alloy steel. Fixed sections - 1 to 7. Simpler than sectional, fewer leak points, lower cost.

Control options: manual, hydraulic, pneumatic, electro-pneumatic, electro-hydraulic, solenoid, joystick, cable. Temperature range: -40°C to +80°C. Viscosity: 15 to 75 mm²/s.

120 L/min isn't just a number. It's about what your equipment can do.

A telehandler lifting and extending simultaneously needs flow. 120 L/min keeps the boom moving without bogging down.

A forklift lifting heavy loads needs flow. 120 L/min keeps the lift fast and responsive.

A medium excavator running arm, boom, swing, and blade at the same time needs flow. 120 L/min gives you enough to keep them all moving.

Compared to 80 L/min, 120 L/min is 50% more flow. That's the difference between a machine that works and a machine that works fast.

1. Controlling Movement Direction: By switching the oil circuit, directly control the extension/retraction of the hydraulic cylinder or the forward/reverse rotation of the hydraulic motor.

Examples: Excavator boom and arm movements, lifting and lowering of a lifting platform.

2. Stop and Lock:Utilize the neutral position to cut off the oil circuit, allowing the actuator to precisely stop and maintain its position.

Examples: Crane suspending heavy objects, clamping workpieces and maintaining pressure.

3. System Unloading and Energy Saving: In the neutral position, the oil pump output is directly returned to the oil tank, allowing the pump to operate under zero pressure and no load.

Example: Energy saving and consumption reduction during injection molding machine cooling standby.

Table(1)

Controls direction. Switches oil flow to extend or retract cylinders, forward or reverse motors. Excavator boom and arm, lifting platforms - that's direction control.

Stops and locks. The neutral position blocks flow. The actuator stays put. Crane holding a load, clamp holding a workpiece - that's lock.

Unloads and saves energy. In neutral, pump flow goes back to tank at low pressure. The pump runs, but it's not working hard. Injection molding machines do this during cooling - saves energy, reduces heat.

The P120 Series Hydraulic Monoblock Valve is for equipment that needs the highest flow in the P series:

Telehandlers - boom lift, extension, and attachment control

Forklifts - lift, tilt, and side shift

All-terrain cranes - lifting and swing control

Stackers - material handling

Aerial work platforms - boom and platform control

Motor graders - blade and wheel control

Medium and compact excavators - arm, boom, swing, blade

Skid-steer loaders - bucket and attachment control

Compact wheel loaders - lift and bucket control

Pre-installation check. Inspect the valve body for damage during shipping. Clean all piping before connecting - contamination is the main cause of spool sticking.

Mounting bolts. Tighten diagonally, in stages, to the specified torque. Uneven tightening distorts the body and binds the spools.

First start. Run at low pressure first to purge air. Check for leaks before full operation.

Oil. Don't mix new and used oil. Used oil contains impurities - mixing them wastes the oil change. Drain and clean the system before adding new oil.
