Where This Valve Fits
The DCV100 is a sectional valve - built from individual sections bolted together into one stack. Each section controls one function.
100 L/min at 350 bar. Available with 1 to 12 sections.
It's the middle of the DCV series. Not the smallest, not the biggest. If you're looking at the DCV60 and wondering if it's enough, the DCV100 is probably where you'll end up. It's the one that handles most mid-size equipment without going all the way to 140 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 140 L/min is more than you need.
For equipment that fits this flow and pressure range, the DCV100 Sectional Directional Valve is a practical, no-fuss choice.
Application
Based on its flow rating and sectional construction, the DCV100 Sectional Directional Valve typically ends up on:
Mid-Size Loaders
Boom, bucket, steering, and auxiliary functions. The 100 L/min flow keeps the machine moving fast. Operators notice the difference when stacking material - the boom comes up without that lag.
Excavators
Arm, bucket, swing, and attachments. On a machine like this, cycle time is money. The DCV100 moves enough oil to keep everything responsive.
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.
Forklifts
Mast tilt, lift, and side-shift. The compact sectional design fits in tight equipment compartments.

Installation Checks
Mounting surface. The surface must be flat and clean. An uneven surface distorts the valve body when the mounting bolts are tightened. Distortion causes spools to bind and seals to leak. Check the surface with a straight edge before installation.
Tie rod torque. Sections are held together by tie rods. Tighten them evenly and in sequence. Uneven torque is the most common installation mistake. It distorts the section bodies, increases internal leakage, and causes spools to stick. Use a torque wrench. Do not estimate.
Hydraulic line flushing. Flush all lines before connecting them to the valve. Debris left in the lines will travel into the valve and score the spool bores or block the pilot passages. Flushing is not optional.
Port connections. The DCV100 uses standard hydraulic ports. Confirm that the fittings match the port threads. Cross-threading or over-tightening can damage the port and cause external leakage.
First start. All levers should be in neutral. Start the pump and let it idle for a few minutes. Cycle each section through its full range several times to purge air. If a cylinder moves in the wrong direction, swap the A and B lines on that section.
Routine Maintenance
Oil cleanliness. Contamination is the leading cause of spool sticking and premature wear. Keep the oil clean. Replace filters on schedule. Do not open the hydraulic system unless necessary. When you do open it, protect the openings from dust and debris.
Tie rod torque check. Check tie rod torque periodically. Vibration can loosen the rods over time. A loose stack will leak between sections and may cause erratic spool movement.
Lever dust boots. Inspect the dust boots around the lever pivots every 500 hours. Replace any that are cracked or missing. Damaged boots allow dust and moisture into the spool bore.
External leakage. Check the mounting face and the joints between sections for weeping. A small weep usually indicates a damaged O-ring or uneven tie rod torque. Address it before it becomes a larger leak.
Oil temperature. The valve is rated for ambient temperatures from -40°C to +80°C. If the oil runs hot, check the system relief valve setting and the oil cooler. High oil temperature accelerates seal degradation and reduces oil viscosity.
Fault Diagnosis
A section does not respond. The spool may be stuck. Possible causes: contamination in the spool bore, a broken spring, or a bent lever linkage. Remove the end cap and inspect the spool. If the spool is scored or stuck, the section may need replacement.
A function moves slowly. The actuator may be starved of flow. Check the pump output and the system relief valve. If the pump is delivering full flow and pressure, the problem may be internal leakage in that section. Internal leakage of 15 cc/min at 160 bar is the specification. If leakage is significantly higher, the spool or bore may be worn.
A function drifts under load. The load check valve in that section may be leaking. Or the spool may not be centering fully. Check the spool centering first. If the spool centers properly, the load check valve may need replacement.
All sections fail at once. The problem is in the common components, not the individual sections. Check oil level, oil viscosity, suction filter, and pump output. A clogged suction filter or low oil level will affect every section simultaneously.
External leakage between sections. Uneven tie rod torque is the most likely cause. Re-torque the tie rods evenly and in sequence. If leakage persists, the section seals may be damaged. In that case, the affected section must be removed and resealed.
The valve is noisy. Noise usually indicates air in the oil or a restricted inlet. Check the oil level and the suction line. Bleed the system if air is present. If the noise is a high-pitched whistle, a pilot passage or orifice may be partially blocked.

Strong & Reliable
The DCV100 is a high-performance, sectional (modular) directional control valve designed for medium-to-high pressure, medium-flow hydraulic systems. It is widely used in mobile machinery and industrial equipment to control the direction, start/stop, and speed of multiple hydraulic actuators (cylinders, motors).
FAQ
Q: What is the most common cause of a section not responding?
A: A stuck spool. Contamination in the spool bore, a broken spring, or a bent lever linkage can prevent the spool from moving. Remove the end cap and inspect the spool. If it is scored or stuck, the section may need replacement.
Q: Why does a function move slowly even when the pump is delivering full flow?
A: Internal leakage in that section is a likely cause. The specification is 15 cc/min at 160 bar. If leakage is significantly higher, the spool or bore may be worn. Check the load check valve as well.
Q: Why choose DCV100 over DCV60?
A: Flow. DCV60 is 60 L/min. DCV100 is 100 L/min - 67% more flow. If your mid-size equipment needs faster cycles or drives bigger cylinders, the DCV100 gives you the extra capacity without jumping all the way to 140 L/min.
Q: What if I need more flow later?
A: If your equipment grows beyond 100 L/min, you can upgrade to a DCV140 or DCV200. The DCV100 is the mid-range option - it's not meant to be the last valve you ever buy, but it covers most mid-size equipment.
Q: Can the DCV100 be repaired if it develops a problem?
A: Yes. On a sectional valve, individual sections can be replaced. Disassemble the stack, remove the damaged section, install a new one, and reassemble. We recommend having our team do this unless you're experienced.
Q: What should I do if oil is seeping from the valve body?
A: Check the through-bolts - if loose, torque them to spec. If bolts are secure, check the section seals for wear or damage. Seepage between sections usually means worn seals.
Q: What if I need the valve quickly?
A: We can expedite production and ship by air freight. Additional cost applies. Contact Cathy with your deadline.
