When 40 L/min Is Not Enough
You have been running a 40 L/min valve. The machine works, but the cycle feels slow. The operator waits. Productivity drops.
You do not need a sectional valve. You do not need 200 L/min. You need more flow - about twice as much.
The P80 delivers 80 L/min. Same monoblock construction. Same one-piece body. Same manual control. Just more flow.
It is built for medium equipment that needs more flow than the P40 but still wants the simplicity of a monoblock valve.
The P80 Series - Monoblock Valve for Medium Equipment is the natural step up from the P40.
What You Get
Twice the flow of the P40. 80 L/min instead of 40. Enough to make a real difference on medium equipment. Faster cycles. Quicker response. Better productivity.
Same monoblock simplicity. One piece of iron. No assembly. No tie rods. No seals between sections. Fewer leak points.
25 MPa. Enough pressure for medium equipment.
Phosphated surface. Corrosion protection. Passes 48-hour salt spray.
Manual control. Lever on each section. No electricity. No wiring.
1 to 7 sections. Order what you need. Nothing extra.
Proven design. Iron castings. Precision machining. Ground spools. Built to last.

Where the P80 Fits
Loaders and excavators. Medium-sized machines that need more flow than 40 L/min. The P80 keeps them moving.
Agricultural machinery. Larger tractors and harvesters. 80 L/min for bigger cylinders.
Industrial equipment. Presses and material handlers. Faster cycles with higher flow.
Mobile equipment. Utility vehicles, sweepers. More flow when you need it.
Marine applications. Deck machinery. Phosphated surface handles salt.
If the P40 is not enough flow, the P80 Series - Monoblock Valve for Medium Equipment gives you the extra capacity in the same monoblock package.
Manufacturing Process
Casting. Iron castings inspected. One piece per valve.
Machining. Bores, ports, and faces machined in one setup.
Assembly. Spools inserted. End caps fitted. Levers attached.
Testing. Every valve tested for leakage and pressure.
Phosphating. Surface treated. Salt spray tested.
Packing & Shipping. Cartons or cases. Worldwide delivery.

How to Order
Ordering a P80 valve is straightforward. You need to specify three things:
1. Series
P80. That is fixed.
2. Number of sections
1 to 7 sections. Each section controls one hydraulic function. Count how many functions your machine needs. Order that many sections. You cannot add sections later, so get it right upfront.
3. Quantity
How many valves do you need? Standard valves have no minimum order. Custom valves require at least 10 pieces.
How to place an order
Contact Cathy by email or WhatsApp. Tell her the three items above. She will confirm availability, price, and delivery time.
For standard valves, we usually ship within 2-3 business days if in stock, or 10-14 business days if not. For custom valves, lead time depends on the complexity-typically 15-25 business days.
What you get with your order
Each valve comes with the standard packing list and inspection certificate. The inspection certificate confirms the valve passed our ten-step test. If you need additional documents-dimensional drawings, hydraulic schematics, or detailed test data-request them when you order. We will include them with the shipment.
Payment terms
T/T for larger orders. Paypal, Western Union, or MoneyGram for smaller amounts. Payment terms are negotiable for regular customers.
FAQ
Q: What is the flow rating of the P80?
A: 80 L/min. That is twice the flow of the P40. If your equipment has been running on 40 L/min and the cycle feels slow, this is the upgrade you need. The extra flow cuts cycle times and boosts productivity.
Q: What is the pressure rating?
A: 25 MPa. Same as the P40. The P80 gives you more flow at the same pressure. No need to upgrade your entire hydraulic system.
Q: What control method is available?
A: Manual lever. Each section has its own lever. The operator moves the lever directly. No electricity. No wiring. No solenoids to fail. Simple and reliable. The lever gives you direct feel of the spool position.
Q: What is a monoblock valve?
A: One piece of cast iron with multiple sections machined into it. No assembly required. No seals between sections. Fewer leak points. Simpler installation. Lower cost than sectional valves. That is why monoblock valves are the standard choice for compact and medium equipment.
Q: Can I add sections to the P80 later?
A: No. The valve is cast as one piece. You cannot add sections after it is made. Order the number of sections you need upfront. If your machine might need more functions later, consider a sectional valve instead.
Q: What machines typically use the P80?
A: Loaders, excavators, larger tractors, harvesters, presses, material handlers, and marine deck machinery. Any medium equipment that needs more than 40 L/min but does not need a sectional valve.
