At 200 L/min, you're not just moving more oil. You're changing how the machine behaves.
Here's the thing about high flow: when you're running multiple functions at the same time-lifting, tilting, steering, running an attachment-the pump's output gets divided. Each function gets a piece of the total flow. At 140 L/min, each piece is smaller. At 200 L/min, each piece is bigger.
What does that feel like to the operator? The boom lifts without hesitation. The bucket curl keeps its speed even when the steering is working. The attachment doesn't starve. The machine stays responsive, not sluggish.
The DCV200 Manual Control For High-Flow Equipment isn't the valve for everyone. It's for equipment that runs multiple functions simultaneously-where 140 L/min is borderline but you don't want to look outside the DCV series. It's the largest flow we offer in this family, and it's built for machines that need it.
Why This Valve Exists
Some valves are designed for versatility. This one is designed for capacity.
The Flow
200 L/min at 350 bar. This is serious flow-for big pumps, big cylinders, big equipment. Not compact machines. Not mid-range. The kind of equipment where cycle time is measured in seconds, not minutes, and a faster cycle means more production at the end of the day.
The Construction
Sectional. Sections bolt together, each with its own spool, springs, and detent. You build the stack to match your machine. Add sections later if you add functions. This isn't a monoblock-you're not locked in.
The Details
Phosphating: passes 48-hour salt spray. Not paint, won't peel.
Leakage: 15 cc/min at 160 bar. Same as the rest of the series. The larger spool gives more sealing surface area, so leakage stays under control.
Mounting: M12 bolts, 30° angle (see drawing).
Working Methods
The principle is as old as hydraulic systems themselves. Push the lever, the spool shifts inside its bore, and oil changes direction. The cylinder extends or retracts. Release the lever, springs push the spool back to center, and the oil stops moving.
No electronic signals. No circuit boards. No software to update. Just a lever connected directly to a spool inside a block of machined iron. It works because it's simple - and simplicity is what keeps it working when other things fail.
The DCV200 can hold up to 12 sections. Each section is independent - its own lever, its own spool, its own A and B ports. But they all share the same P port, drawing oil from the same source. One section might control the lift; another controls tilt; a third handles steering. Each does its job without interfering with the others.
Add sections when you add functions. Remove them if you need to reconfigure. The valve changes with your machine - not against it.
Specifications
| Parameter | Value | What It Means |
|---|---|---|
| Control method | Manual | Direct lever operation. No electronics, no wiring. Simple and reliable. |
| Nominal flow | 200 L/min | The rated flow capacity. If your pump delivers 200 L/min or less, this valve keeps up. |
| Viscosity range | 12–400 CST | Most standard oils fall within this range. Outside it, performance suffers. |
| Operating pressure | 350 bar (35 MPa) | Maximum operating pressure. Set your relief valve at or below this. |
| Internal leakage | 15 cc/min @160 bar, 50°C | Leakage at neutral under 160 bar at normal operating temp. Tight enough that you won't notice drift. |
| Ambient temperature | -40°C to +80°C | The valve works in these conditions. Outside this range, we should talk. |
| Valve structure | Sectional | Sections bolt together. Add or remove as your machine changes. |
| Surface treatment | Phosphating | Chemical conversion coating. Not paint - won't peel when bumped. Passes 48-hour salt spray. |
| Valve sections | 1 to 12 | One section per function. Specify the number when ordering. |
| Rustproof level | 48h neutral salt spray test | Standard industrial corrosion protection. |
About The Company
Shijiazhuang Laiye Import & Export Trading Co., Ltd., part of Hebei Onederful® Hydraulic Technology Co., Ltd., has been manufacturing hydraulic components since 1988 - over 35 years of experience. We are a factory, not a trading company, with around 200 employees and a full in-house production process covering machining, assembly, testing, and phosphating. Every valve is individually tested, not spot-checked, with test data filed against its serial number for full traceability. We export to more than 20 countries, hold ISO 9001 certification, and offer OEM customization, technical support, and a 12-month warranty. Material certificates, test reports, and certificates of origin are available upon request - because we believe you need more than just parts; you need peace of mind.
Production Process
Raw Material Inspection
Iron castings and steel arrive with mill certificates. We verify each batch through spectral analysis for material composition and inspect for internal defects. Any material that doesn't meet spec gets rejected at the door - we don't compromise on raw materials.
↓
Precision Machining
Each valve body goes to the CNC machining center. Because the DCV200 is a sectional valve, every working section is machined individually before assembly. We hold tolerances to microns - the kind of precision that makes the difference between a valve that seals and one that seeps.
↓
Heat Treatment
Once machined, the bodies go through heat treatment. This relieves internal stress from the cutting process, improves wear resistance, and locks in dimensional stability so the valve holds its geometry over years of use. It's what keeps the spool moving smoothly long after the machine has left the factory.
↓
Spool Lapping
This is where internal leakage is won or lost. Each spool is precision-ground, then measured against its matching bore. Based on the actual clearance, we lap it to final spec. It's tedious work, but it's what keeps leakage at 15 cc/min instead of 50 - and why our valves hold position when others drift.
↓
Surface Treatment
The valve bodies are phosphated. This isn't paint - it's a chemical conversion coating that bonds at the molecular level. If the valve gets knocked, the coating stays. No peeling. No rust creep underneath. We salt-spray random samples to confirm they pass 48 hours, which means the valve holds up in standard industrial environments.
↓
Assembly
Working sections, inlet, and outlet end cover get stacked and pulled together with through-bolts. We use seals from trusted suppliers and torque every bolt to spec. Each assembler stamps their work - if something comes up later, we know who built it. This is traceability at the operator level.
↓
Pressure Testing
Every valve gets tested. Not every tenth one. Not a random batch sample. Every single valve goes on the test stand. We check neutral leakage, pressure drop across each section, lever effort through the full stroke, and external leaks under pressure. The test data is recorded and filed against the serial number - if you ever need to look it up, we can pull it.
↓
Final Inspection
One last look - 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: Can the DCV200 Manual Control For High-Flow Equipment be mounted in any orientation?
A: Yes, but horizontal with levers facing up is recommended for best lever feel and longest spring life. Other orientations may affect centering due to gravity.
Q: How do I check for internal leakage?
A: Watch the cylinder. If it drifts in neutral, internal leakage may have increased. We can test the valve at our facility to confirm the leakage level.
Q: What is the torque spec for the through-bolts?
A: Through-bolt torque is critical for proper sealing between sections. Contact us for the specific torque spec - it varies with the number of sections and configuration.
Q: Can I order the DCV200 with a different lever shape or length?
A: Yes. For OEM customers, we offer custom lever shapes, lengths, and handle grips. Minimum quantity applies.
Q: What is the DCV200's typical application?
A: Large wheel loaders, large excavators, heavy construction machinery, marine winches, and extreme-duty industrial systems. Anywhere the flow demand exceeds what a 140 L/min valve can deliver.
Q: Does the DCV200 come with overload valves?
A: Not as standard, but each section has pre-drilled ports for optional overload valves. These allow individual pressure limiting per function - useful when different actuators need different pressure settings.
Q: Can the DCV200 be mounted in any orientation?
A: Yes, but horizontal with levers facing up is recommended for best lever feel and longest spring life. Other orientations may affect centering due to gravity.
