Product details

I. Model Interpretation & Structural Features

1. Model Composition

• DCVL: Series identifier, typically representing ahigh-pressure multi-way directional control valvewith a rated pressure of up to350 barand flow capacity ranging from20–200 L/min(total flow for dual-section valves may be higher).

• 15: Likely denotes thenominal diameter (DN15)or flow coefficient (e.g., KV value of 15). Confirm with specific parameter tables.

• -5: Explicitly indicates adual-section (dual-unit) design, integrating two independent control units in a single valve body for simultaneous management of two pneumatic actuators (e.g., dual cylinders or motors).

2. Key Structural Features

• Modular Dual-Section Design:

• Reduces connection points and leakage risks.

• Saves installation space, ideal for synchronized control of two actuators (e.g., excavator boom and bucket linkage).

• Material & Construction:

• Valve body: High-strength cast iron or ductile iron.

• Seals: Wear-resistant rubber or PTFE for long-term pressure resistance and sealing.

• Safety Features:

• Built-in overload protection valves (prevent system overpressure).

• Manual emergency operation (for manual switching if pneumatic control fails).

II. Core Performance Parameters

【表格】

Parameter Typical Value for DCVL15-5 Notes

Working Pressure ≤350 bar (some applications up to 40 bar) Pneumatic valves typically operate at lower pressures than hydraulic valves (up to 50 MPa).

Flow Range 60–200 L/min (per section) Total flow for dual-section valves: 120–400 L/min (verify by model).

Control Modes Pneumatic, manual, electric (optional) Supports hybrid control (e.g., one section pneumatic, one manual).

Temperature Range -40°C to +80°C Seals must maintain elasticity within this range.

Port Types G3/4, SAE12, etc. (confirm) Must match system piping (threaded or flanged connections).

III. Typical Applications

1. Construction Machinery

• Excavators: Synchronized control of boom and bucket cylinders for compound motions (e.g., digging and dumping).

• Cranes: Management of telescopic cylinders and slewing motors for enhanced operational safety.

2. Municipal Vehicles

• Garbage Trucks: Coordination of compression plates and packing mechanisms for optimized waste loading.

• Street Sweepers: Dual-brush synchronization for efficient cleaning.

3. Industrial Automation

• Assembly Lines: Simultaneous clamping/transport of workpieces by dual cylinders for precision positioning.

• Packaging Machinery: Synchronized sealing and cutting for high-speed, high-quality packaging.

IV. Selection & Customization Guidelines

1. Confirm Control Modes

• Choose betweenpure pneumatic, pure manual, or hybrid control(e.g., dual-section valves with mixed modes).

• For electric control, verify compatibility with electromagnetic valve modules.

2. Match Flow & Pressure

• Ensure per-section flow meets individual actuator demands (e.g., select ≥80 L/min per section for an 80 L/min cylinder).

• Validate system pressure ≤ valve’s rated pressure (e.g., 350 bar).

3. Ports & Installation

• Confirm port type (e.g., G3/4) matches system piping.

• Evaluate space constraints; prioritize compact designs (e.g., stacked or segmented valve groups).

4. Supplier Support

• Select vendors offeringcustomization(e.g., adjustable section count, control modes, or integrated functions).

• Ensure rapid after-sales support (e.g., 24/7 technical assistance, 48-hour on-site repairs).
