Product details

Explosion-proof Solenoid Directional Control Valve 4WE10 FB

This hydraulic control component is specifically designed for hazardous environments, integrating explosion-proof functionality with the core features of a solenoid directional control valve. Below is a detailed introduction:

------

I. Core Functions

1. Directional Control

• Driven by solenoids, the valve spool shifts to switch oil paths in hydraulic systems, controlling the motion direction of actuators (e.g., hydraulic cylinders, motors).

• Supports multiple valve configurations (e.g., 2-position 4-way, 3-position 4-way) to meet diverse operational requirements.

2. Explosion-proof Design

• Enclosure Protection: Utilizes explosion-proof housings (typically cast iron or stainless steel) compliant with international standards (e.g., ATEX, IECEx), isolating internal sparks from explosive atmospheres.

• Sealing Structure: Dual-seal design prevents hydraulic oil leakage and blocks flammable media from entering the valve body, reducing explosion risks.

• Electrical Safety: Built-in explosion-proof solenoids limit current and voltage to suppress arcing, ensuring safe operation in flammable/explosive settings (e.g., mines, chemical plants, oil/gas platforms).

------

II. Technical Specifications

• Model: 4WE10 FB ("FB" denotes explosion-proof variant)

• Pressure Range: Up to 315 bar (model-dependent), suitable for high-pressure hydraulic systems.

• Flow Capacity: Max. 100 L/min, ideal for medium-to-large hydraulic equipment.

• Power Supply: Supports DC (e.g., 24V DC) or AC (e.g., 220V AC) for compatibility with industrial power systems.

• Mounting Interface: Conforms to ISO 4401 standards, enabling direct replacement of similar valves from other brands to reduce maintenance costs.

• Environmental Adaptability: Operates in temperatures from-20°C to +80°C, withstanding extreme conditions.

------

III. Structural Features

1. Modular Design

• Independent replacement of components (e.g., valve body, solenoid, spool) without disassembling the entire valve, minimizing downtime.

2. High-Strength Materials

• Valve body crafted from high-grade cast iron or stainless steel; precision-machined spool ensures minimal internal leakage and a long service life (>5 million cycles).

3. Wet-Armature Solenoid

• Direct immersion in hydraulic oil enhances heat dissipation and thermal stability, reducing failures caused by overheating.

4. Manual Override

• Emergency manual operation allows valve position switching during power outages or solenoid failures, ensuring system safety.

------

IV. Applications

1. Oil & Gas

• Used in drilling platforms and pipelines to prevent explosions triggered by electrical sparks.

2. Chemical Industry

• Controls hydraulic actuators in equipment handling flammable chemicals during production and transportation.

3. Mining Machinery

• Ensures safe operation of excavators and tunneling machines in environments with gas or dust hazards.

4. Grain Processing & Pharmaceuticals

• Mitigates explosion risks in facilities with dense dust concentrations.

------

V. Key Advantages

• Enhanced Safety: Complies with global explosion-proof standards, minimizing accident risks.

• High Reliability: Modular construction and durable materials guarantee stable long-term performance, reducing downtime.

• Interoperability: Standardized interfaces enable quick integration, lowering system costs.

• Maintenance Efficiency: On-site replacement of seals and coils without full valve disassembly saves time and expenses.
