The 140 L/min Sweet Spot
The DCV140 is the middle child of the DCV family. Not the smallest. Not the largest. Just right for a lot of heavy equipment.
40% more flow than DCV100. That is the headline. DCV100 gives you 100 L/min. The DCV140 gives you 140 L/min. Same footprint. Same sections. The difference is inside-larger passages let more oil through without increasing pressure drop.
Same footprint, easy upgrade. The DCV140 mounts the same way as the DCV60 and DCV100. Same tie rod layout. Same section width. Same bolt pattern. If you already have a DCV100 manifold, the DCV140 bolts right on. No machining. No redesign. Just swap and go.
Same control options. Manual, pneumatic, electro-hydraulic. Pick the one that fits your operator. Change it later if you need to. The control mechanism is the only thing that changes-the valve sections underneath stay the same.
Phosphated surface. Corrosion protection built in. No paint to chip. Passes 48-hour salt spray. If your equipment works outdoors or near salt water, this matters.
Low leakage. Oil goes where it should, not past the spool. That means efficient operation and less heat.
Built for heavy work. Iron castings, precision-machined bores, ground spools. No shortcuts. This valve is designed for machines that work hard every day.
Room to grow. If you are designing a new machine and 100 L/min looks marginal, the DCV140 gives you headroom. You do not have to run right at the limit. The extra capacity means faster cycles, better productivity, and less strain on the system.
Which Flow Rating Do You Need?
The DCV series comes in four flow ratings:
| Series | Flow | Best For |
|---|---|---|
| DCV60 | 60 L/min | Medium-duty machines, smaller cylinders |
| DCV100 | 100 L/min | Larger machines, faster cycles |
| DCV140 | 140 L/min | Heavy equipment, high-speed operations |
| DCV200 | 200 L/min | Largest machines, extreme flow demands |
The DCV140 sits in the middle. It is for applications that need more than 100 L/min but do not need 200 L/min. Large excavators. Heavy presses. High-speed material handlers. The DCV140 gives you the extra capacity without oversizing.
The DCV140 Series - High-Flow Sectional Valve delivers 140 L/min in the same modular package.

Control Options
Manual. You pull a lever. The spool shifts. Simple as that. No wires, no solenoids, no electrical problems to chase.
Pneumatic. Air pressure does the work. Push air into the pilot, the spool shifts. No wiring. Good for places where you do not want sparks.
Electro-hydraulic. Solenoids manage the pilot pressure. Flip a switch or push a button in the cab. The valve shifts. Good for remote operation and automated systems.
The sections are the same for all three. Only the pilot mechanism changes. Pick the one that works for your operator and your application.
Applications That Need 140 L/min
Large excavators. Big booms, big buckets. Fast cycles need high flow.
Heavy presses. Large cylinders move quickly with 140 L/min.
Material handlers. Faster lifting and lowering cuts cycle time.
Marine winches. Higher flow for faster line speeds.
Large harvesters. Big machines need big valves.
Mining equipment. Heavy-duty machines need high flow.
If 100 L/min is not enough, the DCV140 Series - High-Flow Sectional Valve gives you the extra capacity.
How We Build These Valves
Casting
Iron castings come in from our foundry. We check every one before machining. Castings with porosity or wrong dimensions get rejected on the spot.
Machining
Each section is machined to size. Spool bores, ports, mounting faces-all held to tight tolerances. If a part does not meet spec, it does not move to the next step.
Spool grinding
Spools are ground to final size. Surface finish and clearance are critical. Too tight and the spool sticks. Too loose and leakage goes up. We hold the spec.
Assembly
Sections are stacked in order. Tie rods run the full length of the stack. Tightened in sequence to the specified torque. Spools inserted. End caps fitted. Every fastener checked.
Testing
Every valve gets tested on the stand. Not sample testing. Leakage measured at rated pressure. Control function verified. If it does not pass, it does not ship.
Phosphating
The assembled body gets a phosphate coating. It protects against corrosion. Samples from each batch are salt spray tested to 48 hours.
Packing
Small orders in cartons with foam. Bulk orders in plywood cases. Test reports included on request.
Shipping
Sea, air, rail, truck, or express. Worldwide. Tracking numbers for every shipment.
FAQ
Q: Why would I choose DCV140 instead of DCV100?
A: Flow capacity. DCV100 tops out at 100 L/min. The DCV140 delivers 140 L/min-40% more flow. If your machine struggles with cycle times or you are upsizing actuators, the extra flow makes a noticeable difference. The upgrade path is simple because both valves share the same footprint.
Q: Can I upgrade from DCV100 to DCV140 without changing the manifold?
A: Yes. The mounting is identical. Same tie rod spacing. Same section width. Same port locations. The valve swaps in directly. No new holes to drill. No new manifold to machine.
Q: Is the phosphating just a coating or something more?
A: It is a surface conversion, not just a coating. The phosphate layer bonds with the metal. It does not chip or peel like paint. It protects against corrosion and passes 48 hours of salt spray testing.
Q: Can I mix control methods across sections?
A: No. All sections share the same pilot mechanism. The control method is consistent across the entire stack.
Q: What kind of maintenance does the DCV140 need?
A: Keep the oil clean and change filters regularly. That covers most of it. Check for external leakage during routine inspections. If performance drops, test internal leakage.
Q: How do I know if the valve is leaking internally?
A: Watch for cylinder creep. If an actuator moves when the spool is centered, internal leakage is likely. You can also test the leakage by measuring flow from the T port with the valve in neutral.
