Where This Valve Fits
The DCV80 is a sectional valve - built from individual sections bolted together into one stack. Each section controls one function.
80 L/min at 350 bar. Available with 1 to 12 sections.
If you're looking at the DCV60 and wondering if it's enough, the DCV80 is probably where you'll end up. It's not the biggest in the DCV series, but it's the one that handles most compact to mid-size equipment without going all the way to 100 L/min. The extra flow over the 60 gives you room to breathe - faster cycles, more responsive operation, less waiting.
It's the valve you choose when you know 60 L/min is borderline but 100 L/min is more than you need.
For equipment that fits this flow and pressure range, the DCV80 Manual Sectional Directional Valve is a practical, no-fuss choice.
A Closer Look
80 L/min - What That Gets You
80 L/min moves bigger cylinders at useful speeds. It's for equipment where the operator notices when flow is restricted - where cycle time matters and waiting costs money. The jump from 60 to 80 is noticeable. Not subtle - noticeable.
The 350 bar pressure rating is the same as the rest of the DCV series. You're not giving up pressure by choosing this flow.
Sectional Construction - Why It Matters
The DCV80 is built from individual sections. Each section is its own valve - spool, springs, detent. You bolt them together. Need three sections? Use three. Need six? Add three more. Need to change the machine next year? You can.
This matters because equipment changes. New attachments, new functions, new requirements. With a sectional valve, you don't replace the whole thing. You just add sections.
Surface Treatment
Phosphating. Passes 48-hour salt spray. Not paint - won't peel when bumped.
Products Description
Installation and Care
Installation
Mount the valve on a clean, flat surface. Torque through-bolts evenly to avoid section distortion. Flush all hydraulic lines before connecting to the valve.
First Start
All levers neutral. Start the pump. Idle for a few minutes. Test each section. If a cylinder moves backward, swap A and B on that section.
Daily Use
Don't open anything while pressurized.
Cold oil? Let it warm up.
If the machine has been sitting, check lever movement.
Keep the valve clean.
Check through-bolt torque periodically - vibration can loosen them over time.
Oil Requirements
Standard mineral-based hydraulic oil - ISO VG 32, 46, or 68.
Recommended viscosity: 12–400 CST.
Keep oil clean - regular oil and filter changes are essential.
Parts That Wear
Lever dust boots. O-rings on fittings. Section seals (when servicing sections).
Section Replacement
If a section fails, you don't replace the whole valve. Disassemble the stack, remove the damaged section, install a new one, and reassemble. That's the advantage of sectional construction.
Where It's Typically Used
Based on its flow rating and sectional construction, the DCV80 Manual Sectional Directional Valve typically ends up on:
Small to Mid-Size Loaders
Boom, bucket, and steering functions. The 80 L/min flow keeps the machine moving fast even with multiple functions running at once. Operators notice the difference when stacking material - the boom comes up without that lag they'd gotten used to.
Compact Excavators
Arm, bucket, swing, and attachments - four to six sections isn't unusual. On a machine like this, cycle time is money. The DCV80 moves enough oil to keep everything responsive, even when you're running multiple functions at once.
Tractors and Harvesters
Implement lift, steering, and auxiliary hydraulics. Farm work is seasonal - you run hard when the weather holds, and you don't stop for breakdowns. The DCV80 holds up to long days without thermal drift.
Material Handling Equipment
Forklifts, aerial work platforms - controlling lift, tilt, and auxiliary functions. The compact size and flexible configuration fit the space constraints of material handling equipment.
