DCV100 control Valve
Are you sure 60 L/min is enough?
That's the first question you should ask yourself before choosing the DCV100 Sectional Directional Valve Flexible Sections.
Many machines ship with a DCV60 - 60 L/min of flow. It's enough when the machine leaves the factory. But then things change. You add an attachment - flow demand goes up. You swap to a larger cylinder - demand goes up. Operating conditions get tougher - demand goes up.
60 L/min gradually becomes not enough. The machine slows down. Productivity drops.
The DCV100 solves that. 100 L/min, 350 bar, 1 to 12 sections, manual control. 40 L/min more than the DCV60 - nearly 70% more flow. Same sectional design, bigger capacity.
If you're running a DCV60 and the machine feels slower than it used to, the DCV100 is the upgrade.
Three questions to decide if you need to upgrade
Question 1: Is your machine running slower?
Measure it. Does a full work cycle take noticeably longer than when the machine was new? If yes, you're likely flow-limited. Attachments added, cylinders enlarged, or internal leakage from wear - whatever the cause, insufficient flow is the bottleneck.
Question 2: Have you added attachments recently?
Every hydraulic attachment needs flow. One attachment might only need 10-15 L/min, but it adds up. If the machine was spec'd with a DCV60 and you've added attachments, the flow may no longer be sufficient.
Question 3: Will you add more attachments later?
This is the one most people overlook. 60 L/min might be enough today. But what about next year? Machine upgrades, new functions, heavier duty cycles - all of these increase flow demand.
Sectional vs monoblock - what you need to know
The difference between sectional and monoblock comes down to one thing: flexibility.
A monoblock valve is a single cast iron piece. Fixed sections. If you need one more function later, you replace the whole valve. High cost, long downtime.
A sectional valve is built from individual sections bolted together. Need another function? Add a section. One section fails? Replace that one. No need to replace the whole valve.
The DCV100 is sectional. If your machine's functions change over time, sectional is the better choice.
How to know you need 100 L/min
Calculate your system's maximum flow requirement, then add a margin. If your calculation is close to 60 L/min, choose the DCV100. The extra flow gives you margin - room for your machine to grow.

Where it belongs
The DCV100 Sectional Directional Valve Flexible Sections is for equipment that needs multiple functions and the ability to change over time:
Loaders and telehandlers - boom, bucket, auxiliary circuits
Medium 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.
Adding sections. Order the extra section, bolt it on, connect the plumbing. No need to replace the whole valve. This is the main advantage of sectional over monoblock.
Port connections. Standard hydraulic ports. Make sure your fittings match.
Maintenance. If one section fails, replace that section. The rest stay in place.

FAQ
Q: What's the difference between DCV100 and DCV60?
A: Flow capacity. DCV100 flows 100 L/min. DCV60 flows 60 L/min. If your system needs more flow, choose DCV100. If 60 L/min is enough, DCV60 is more cost-effective.
Q: How do I know whether to choose a sectional valve or a monoblock valve?
A: Ask yourself one question: will your machine need more hydraulic functions in the future? If yes, go sectional - you can add sections later. If no, monoblock is simpler and cheaper.
Q: What's the most common mistake during installation?
A: Uneven tie rod torque. Sectional valves are held together by tie rods. If torque is uneven, the sections distort - spools bind, internal leakage increases, the valve doesn't work right. Tighten evenly and in sequence to the specified torque.
Q: What are the mounting surface requirements?
A: The surface must be flat and clean. An uneven surface distorts the valve body and causes seal failure. Check the surface before installation.
Q: What if all sections fail simultaneously?
A: The problem is in the common components - low oil supply, low viscosity, low oil level, or clogged suction filter. Check common components first, then each section.
Q: How do I know if a section has internal leakage?
A: The actuator moves slowly or drifts without command. Internal leakage usually comes from spool wear or worn seals. If one section leaks, replace that section only.
