What Makes This Valve Different
The P120 is a monoblock valve - one solid piece of iron. No sections bolted together. No seals between sections because there are no sections.
120 L/min at 250 bar. Available with 1 to 7 sections. G1 inlet and outlet, G3/4 work ports.
Here's what sets the P120 apart from the smaller P40 and P80: it's built for equipment that needs more flow and more sections. 1 to 7 sections - more than the P120's 1-4 in other configurations. And the G1 ports are bigger, matching the higher flow.
It's a monoblock, so what you order is what you get. No adding sections later. But for equipment with fixed functions - telehandlers, forklifts, cranes, mid-sized excavators - monoblock makes more sense than paying for sectional flexibility you'll never use.
For equipment that needs 120 L/min and up to seven functions, the P120 G1 Oil Port is a straightforward choice.
A Closer Look
120 L/min - The Flow for Mid-to-Large Equipment
120 L/min is enough for telehandlers, mid-sized excavators, forklifts, and agricultural machinery. The flow that sits between the smaller stuff and the really big stuff - where a lot of equipment actually lives.
250 bar max pressure - enough for most medium-to-high pressure hydraulic systems.
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.
G1 Ports - Built for Higher Flow
The G1 inlet and outlet ports are bigger than the G3/4 ports you'll find on smaller P-series valves. They match the 120 L/min flow - big enough to move the oil without restriction. If your system already uses G1 fittings, the P120 G1 Oil Port fits without adapters.
Integrated Safety Valves
Built-in overload relief valves and anti-cavitation valves on the work ports. System protection without external valve blocks. One less thing to add.
Multiple Control Options
Manual, flexible shaft, pneumatic, electric - choose what fits your machine. Manual is standard. The others are optional.
Where It's Typically Used
Based on its flow rating and monoblock construction, the P120 typically ends up on:
Telehandlers
Boom lift, extension, and attachment functions. The 120 L/min flow matches the pump output of mid-to-large telehandlers.
Forklifts
Mast tilt and lift functions. The 120 L/min moves the mast faster - matters in busy warehouses where every second counts.
Mid-Sized Excavators
Arm, bucket, and auxiliary functions. The 120 L/min flow keeps everything responsive, even when running multiple functions at once.
Loaders and Dump Trucks
Boom, bucket, and steering functions. Operators notice the difference when stacking material - the boom comes up without that lag.
Harvesters and Concrete Pump Trucks
Implement control and pump functions. Seasonal work demands reliability - the P120 holds up to long days.

Our production and equipment
Raw Material Casting
Iron castings are produced in our own foundry. We control the material composition from the start. Each batch is inspected for internal defects and material quality.
↓
Precision Machining
Valve bodies go to CNC machining centers. The P120 is a monoblock valve - the entire body is machined from a single casting in one setup. All spool bores, mounting surfaces, and porting are completed to micron-level tolerances.
↓
Heat Treatment
Machined bodies undergo heat treatment. This relieves internal stress, improves wear resistance, and locks in dimensional stability so the valve holds its geometry over years of use.
↓
Spool Carburizing & Hard Chrome Plating
Spools are carburized for surface hardness, then hard chrome plated. This reduces wear and extends service life - especially important in applications that cycle frequently.
↓
Spool Grinding
Each spool is precision-ground to final dimensions. Clearances are held to tight tolerances - this determines internal leakage performance.
↓
Assembly
The valve body, spools, springs, seals, and levers are assembled. Each section is checked for proper movement. Each assembler stamps their work for traceability.
↓
Pressure Testing
Every valve is individually tested - not spot-checked. Pressure tests, seal integrity checks, and flow performance tests are performed. Test data is filed against the serial number.
↓
Surface Treatment
Valves are phosphated, painted, or Dacromet coated - depending on customer specification. Surface treatment provides corrosion protection for outdoor equipment.
↓
Final Inspection & Packaging
One last check - appearance, marking, packaging. If it passes, it goes to inventory. If it doesn't, it goes back. We don't ship valves we wouldn't use ourselves.
FAQ
Q: Is the P120 in stock? How do I check availability?
A: Contact the sales team directly-give them the model, number of sections, and control type, and they'll check stock for you. Standard models are usually in stock; non-standard ones need to be scheduled for production.
Q: How does OEM customization work?
A: You provide the specs, mounting dimensions, and branding requirements. We'll draw up plans for your approval, then make a sample. Once the sample passes testing, we move to mass production.
Q: What equipment is the P120 good for?
A: The P120 is used on mid-to-large gear-telehandlers, forklifts, cranes, mid-sized excavators, loaders, dump trucks, concrete pump trucks, and harvesters. It's a good fit when space is tight, functions are fixed, and you don't plan to add anything later.
Q: What if oil is seeping from the valve body?
A: First, check the mounting bolts-if they're loose, torque them back to spec, tightening in a diagonal pattern. If bolts are fine, check the port seals for wear or damage. If it's seeping at the mounting face, you may need new seals or to check if the surface is flat.
Q: What if the valve spool sticks?
A: Start by checking the oil-if it looks dirty, take the spool out, clean it and the bore, then put in fresh oil and a new filter. If the spool is scored or worn, you'll need to replace it.
