Where This Valve Fits
The DCV100 is a sectional valve - built from individual sections bolted together into one stack. Each section controls one function. You can add or remove sections as your machine changes.
100 L/min at 350 bar. This is the mid-range workhorse of the DCV series. More flow than the DCV60, less than the DCV140. If your equipment needs more than 60 L/min can provide, but 140 L/min would be overkill, the DCV100 is the practical answer.
Sectional construction gives you flexibility. Start with what you need today. Add sections next year if your machine changes.
For equipment that fits this flow and pressure range, the Sectional Directional Valve DCV100 - 100 L/min is a solid, dependable choice.
A Closer Look
100 L/min at 350 Bar
100 L/min nominal flow. 350 bar max pressure. The extra 40 L/min over the DCV60 makes a real difference - faster cycle times, more responsive operation, better productivity.
Sectional Flexibility
Built from individual sections - each with its own spool, springs, and detent. Need more functions later? Add sections. Need to reconfigure? Remove sections. You're not locked in.
Surface Treatment
Phosphating. Passes 48-hour salt spray. Chemical conversion coating - not paint, won't peel.
Internal Leakage
15 cc/min at 160 bar, 50°C. Same spec across the DCV series.
The Sectional Directional Valve DCV100 - 100 L/min is built for mid-range equipment where flexibility and flow matter.
How It Works
Push the lever. The spool moves. Oil redirects from P to either A or B. The cylinder moves. Release the lever, springs return the spool to center. Flow stops.
No sensors. No circuit boards. No software. Just a lever, a spool, and a machined body.
Up to 12 sections. Add or remove as needed. Each section operates independently - one controls lift, another controls tilt, a third might control steering. All sections share the same P port. Each has its own A and B ports.

Production Process
Raw Material Inspection
Iron castings and steel are inspected upon arrival. Each batch undergoes spectral analysis for material composition and internal defect inspection. Non-conforming materials are rejected.
↓
Precision Machining
Valve bodies are machined on CNC machining centers. The DCV100 is a sectional valve - each working section is machined individually before assembly. Tolerances are held to microns to ensure proper spool-to-bore fit.
↓
Heat Treatment
Machined bodies undergo heat treatment to relieve internal stress and improve wear resistance and dimensional stability.
↓
Spool Lapping
Each spool is precision-ground and then fitted to its matching valve body bore. Final lapping is done based on actual clearance measurements. This step directly determines internal leakage performance.
↓
Surface Treatment
Valve bodies are phosphated. This is a chemical conversion coating, not paint - it bonds with the metal and does not peel off when knocked. Random samples are salt-spray tested to verify 48-hour compliance.
↓
Assembly
Working sections, inlet section, and outlet section are assembled with through-bolts. Seals are from reputable brands. Torqued to specification. Operator information is recorded for traceability.
↓
Pressure Testing
Every valve is individually tested - not spot-checked. Test items include neutral position internal leakage, pressure drop, lever operating force, and external leakage. Test data is filed with the serial number for future traceability.
↓
Final Inspection
Final inspection confirms appearance, marking, and packaging meet requirements. Qualified units go to inventory.
About Us
We're a manufacturer, not a middleman. Shijiazhuang Laiye Import & Export Trading Co., Ltd. is part of Hebei Wendefu Hydraulic Technology Co., Ltd. We started in 1988 - over 35 years ago.
The factory has about 200 people. We machine, assemble, and test everything ourselves. Every valve gets tested individually, not as a batch sample. The test results go into a file with the valve's serial number.
FAQ
Q: Does the DCV100 have a built-in relief valve?
A: The DCV100 is a directional valve - it controls flow direction. Pressure relief is handled by a separate relief valve in your system.
Q: How do I know if the DCV100 is the right size?
A: We need your pump displacement, cylinder sizes, and number of functions. Send those to Cathy and we can confirm.
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.
Q: How do I clean the valve?
A: Wipe with a clean cloth and mild solvent. Don't use strong alkaline or acid cleaners. Keep the surface lightly oiled.
Q: Can the DCV100 be used with a closed-center hydraulic system?
A: Different spool types are available for different circuit requirements. Specify your system type when ordering so we supply the correct spool configuration.
Q: Can the DCV100 be used with a hydraulic motor instead of a cylinder?
A: Yes. The valve controls flow direction, so it works with both cylinders and hydraulic motors. The motor will rotate forward or reverse depending on which port gets pressure.
