DCV40 Series
Blince
The DCV40 DCV20 4OT 1 Solenoid Directional Control Valve is a versatile solution designed for precise directional control in high-pressure hydraulic systems, ideal for industrial machinery, automation, and mobile equipment. Engineered with solenoid actuation and multiple spool positions, this valve ensures reliable operation and fast response in demanding applications.
High-Pressure Performance:
Rated for 350 bar (5075 PSI) pressure (DCV40) and 250 bar (3625 PSI) (DCV20), supporting high-force hydraulic actuators (e.g., cylinders, motors).
Solenoid actuation (12V/24V DC, 110V/230V AC), with response time ≤30ms for rapid directional changes in high-frequency cycles.
Precision Spool Design:
4-way, 3-position (4OT) spool configuration (neutral, forward, reverse), with optional detent or spring-centered returns for precise flow control.
Low hysteresis (≤3% of rated pressure), ensuring consistent performance in closed-loop control systems (e.g., CNC machines, robotics).
Durable & Efficient:
Nitrided steel spools (HV 900) and bronze bushings, resisting wear (500,000 cycle life) and reducing internal leakage (≤50 mL/min at rated pressure).
Energy-efficient solenoids (power consumption ≤15W), minimizing heat generation in multi-valve manifolds.
Installation Flexibility:
Subplate mount (ISO 4401) and modular design, compatible with stackable valve manifolds (up to 8 valves per manifold), saving 40% space in hydraulic cabinets.
IP65-rated solenoid coil (NEMA 4X), suitable for wet or dusty environments (e.g., car washes, grain processing plants).
Suited for high-pressure systems, the DCV series is used in:
CNC Machine Tools: Controls hydraulic chucks and tool changers, ensuring precise motion in milling and lathe machines (positioning accuracy ±0.01mm).
Automation Systems: Directs flow to robotic arms and grippers, supporting high-speed pick-and-place operations (cycle times ≤2 seconds).
Mobile Hydraulics: Powers boom and stabilizer functions in cranes and aerial lifts, with vibration-resistant mounts (20G, 10-2000Hz).
Metalworking Equipment: Controls press brakes and shears, with fail-safe neutral position for operator safety during tool changes.
Q: What is the difference between DCV40 and DCV20?
A: DCV40 supports higher pressure (350 bar) and flow (40 L/min), while DCV20 is optimized for lower pressure (250 bar) and flow (20 L/min).
Q: Can it be used with proportional control?
A: Yes, optional proportional solenoids (0-10V input) enable variable flow control (5-100% stroke adjustment).
Q: What is the recommended filtration level?
A: ISO 4406 16/14/11 (≤14μm particles), critical for preventing spool jamming in contaminated fluids.
☆ Auxiliary valve: over-load valve, anti-cavitation valve, combined valve, etc.（not for DCV40-45）
☆ Control type: manual, joystick, cable, pneumatic, solenoid, electro-pneumatic, electro-hydraulic, etc.
☆ Structure: monoblock, sectional.
☆ Carry-over port as hydraulic source for other parts.
