Product Introduction
Monoblock valves are simple. One piece, fixed sections, no seals between them. If you know exactly what you need and won't change it, monoblock works fine.
The DCV60 is not monoblock. It's sectional - built from individual sections bolted together. Each section is a separate function. One section for the boom. One for the bucket. One for the auxiliary circuit. Add a section when you need another function. Remove one if you don't.
This flexibility is the whole point of a sectional valve. If your machine changes, the valve changes with it.
The DCV60 Sectional Directional Valve Manual Pneumatic Electro Hydraulic flows 60 L/min at 350 bar. Available with 1 to 12 sections. Phosphated surface, 48 hours salt spray resistance. Temperature range: -40°C to +80°C. Viscosity: 12 to 400 cSt.
Sectional vs monoblock - the real difference
A monoblock valve is one piece of cast iron. Fewer leak points, simpler installation, lower cost. But it's fixed. What you order is what you get. If you need one more function later, you buy a new valve.
A sectional valve is modular. Sections bolt together. If you need another function, you add a section. If a section fails, you replace that one, not the whole valve.
So which is better? It depends. If your machine has stable, known requirements, monoblock makes sense. If your machine has multiple functions and you want to keep options open, sectional is the way to go.
The DCV60 Sectional Directional Valve Manual Pneumatic Electro Hydraulic is for the second group.
Three control options
The DCV60 supports three control types. You can mix them across sections.
Manual. Pull a lever, the spool shifts. Simple, direct, no electronics. Operators feel what the valve is doing. Good for basic machines.
Pneumatic. Air pressure does the shifting. No electrical solenoids, no wiring. Good for remote control or explosive environments.
Electro-hydraulic. A solenoid-operated pilot valve shifts the main spool. Connects to PLCs and electronic controls. Good for automation and remote operation.
You can put manual control on the boom section, pneumatic on the auxiliary, electro-hydraulic on the attachment. Whatever fits your machine.
Six ways to think about this valve
When you're looking at a sectional directional valve, you're really asking a handful of practical questions. Here's how the DCV60 answers each one.
1. What flow and pressure can it handle?
60 L/min and 350 bar. That's the nominal flow and max operating pressure.
2. How many sections do I need?
1 to 12. Count your hydraulic functions. Each function needs one section.
3. What makes sectional different from monoblock?
Flexibility. You can add sections later. A monoblock valve is fixed.
4. What control options are available?
Manual, pneumatic, electro-hydraulic. You can mix them across sections.
5. How do I install it?
Sections bolt together with tie rods. Tighten them evenly - uneven torque distorts the sections and causes leaks or binding.
6. What about maintenance?
Sectional valves have more seals than monoblock - potential leak points. But you can replace a single section instead of the whole valve. Keep spare sections on hand.

Where it belongs
The DCV60 Sectional Directional Valve Manual Pneumatic Electro Hydraulic is for equipment that needs multiple functions and flexibility:
Loaders and telehandlers - boom, bucket, auxiliary circuits
Compact excavators - arm, boom, swing, blade
Agricultural machinery - tractors with multiple implements
Industrial equipment - machines with multiple hydraulic actuators
Installation notes
Assembly matters. Sections are held together by tie rods. Torque them evenly and in sequence. Uneven tightening distorts the bodies - spools bind, internal leakage increases, the valve doesn't work right.
Port connections. G1/4 ports. Make sure your fittings match.
Control selection. Tell us which sections need which control type when you order. Changing control types later is possible but involves disassembly.
Adding sections. Order the extra sections, bolt them on, connect the plumbing. No need to replace the whole valve. This is the main advantage of sectional over monoblock.
About the company
Shijiazhuang Laiye Import & Export Trading Co., Ltd., part of Hebei Onederful® Hydraulic Technology Co., Ltd., has been making hydraulic components since 1988 - over 35 years.
We're a factory, not a trading company. Around 200 employees. Full in-house production: casting, machining, assembly, testing, phosphating.
Products go to Russia, Europe, the Middle East, South America, and Asia. ISO 9001 certified. Every valve is tested individually, with data linked to its serial number.
Production Process
The manufacturing process follows a standard hydraulic component production sequence. Each step is documented and traceable.
Raw Material Inspection
High-strength cast iron and alloy steel are checked for composition and mechanical properties before anything else happens.
Precision Machining
CNC equipment handles milling, drilling, grinding, and honing to hold tight tolerances on bodies, spools, and end covers. After machining, all parts go through deburring, cleaning, and dimensional verification.
Heat Treatment
Key components such as spools and valve seats undergo hardening to improve wear resistance and extend service life.
Surface Treatment
Phosphating or other rust-proof coatings are applied to protect against corrosion and improve surface durability.
Assembly
Skilled workers install spools, springs, seals, and control parts in sequence, with torque control on each connection.
Pressure Testing
Every assembled valve goes through hydraulic testing-pressure resistance, leakage detection, and functional debugging under rated working pressure.
Final Inspection
Visual inspection, dimensional confirmation, and test data review. Each valve is individually tested, not spot-checked, with test data filed against its serial number for full traceability.
FAQ
Q: Can I add sections to the DCV60 after I've already installed it?
A: Yes. That's the main advantage of sectional over monoblock. Add sections, bolt them on, connect the plumbing. The existing sections stay in place - no need to replace the whole valve.
Q: What's the difference between the DCV60 and a monoblock valve like the P80?
A: The DCV60 is sectional - you can add or remove sections. The P80 is monoblock - one piece, fixed sections. If you need flexibility and your machine might change, choose DCV60. If you know exactly what you need and won't change it, monoblock is simpler.
Q: Can I change the control type on a section after installation?
A: Yes, but it involves disassembly. It's easier to specify the correct control type when ordering. If you need to change later, contact our technical team for guidance.
Q: What if the spool sticks on one section?
A: Contamination is the most common cause - dirt in the spool bore. Work the lever (or cycle the control) a few times to free it. If that doesn't work, remove the section, clean the spool and bore, and check for scoring. Clean oil prevents this.
Q: How do I know if I need a sectional valve or a monoblock valve?
A: Ask yourself one question: will my machine need more hydraulic functions in the future? If yes, go sectional - you can add sections later. If no, monoblock is simpler and more cost-effective.
