Product Description:

High‑Precision Electromagnetic Flow Control

The SD11‑2S Electromagnetic Control Valve 70 LPM 315 Bar G1/2 G3/4 is a powerful and responsive hydraulic directional valve designed for demanding systems that need fast, dependable control. With solenoid (electromagnetic) actuation, this valve enables remote switching with precision—even under high pressure and harsh conditions. Whether for construction machinery, industrial presses, or mobile hydraulic systems, the SD11‑2S brings modern control to classic hydraulic setups.

Key Features & Technical Strengths

The SD11‑2S Electromagnetic control valve provides a range of advantages that make it a smart choice for serious hydraulic systems.

• Flow & Pressure Capacity: It supports up to 70 L/min flow, with a top rating of 75 L/min, and handles pressures up to 5 MPa (315 Bar)—ideal for heavy-duty use.
• Ports & Connections: P, A, B ports use G1/2 BSP threads, and the T (tank) port is G3/4. The pressure connection is 1/2 inch, making it compatible with many hydraulic lines.
• Compact Dimensions: At 25 × 17.5 × 12 cm and weighing 4 kg, the valve fits well in tight assemblies while still offering strong performance.
• Oil Circuit & Design: It uses a parallel circuit layout and an open‑center design (fluid flows from side inlet to outlet when in neutral).
• Clean Operation: The valve supports up to ≤10 µm filtration, so only clean hydraulic oil reaches sensitive parts. It also accepts viscosities from 15 to 400 mm²/s.
• Wide Temperature Range: It works reliably between –40 °C and +80 °C, making it suitable for both cold and hot environments.
• Two‑Way, Double‑Acting: The valve operates in both directions (double-acting) and switches between two states (two-way).
• Construction: Built with strong tube-structure materials suitable for long-term use and resistance to system stresses.

Because of these specs, the SD11‑2S is ideal when you need fast solenoid-driven control without sacrificing hydraulic strength.

How the SD11‑2S Electromagnetic Control Valve Works and Why It Matters

The ability to actuate the valve electromagnetically means you can control hydraulic flow from a distance—without manual levers or mechanical linkages. In practice, this means you can:

• Automate motion sequences in machines
• React quickly to changing loads or system states
• Improve safety by isolating human operators from high-pressure zones

Moreover, thanks to its parallel circuit design, the valve allows multiple actuators to work at once, which helps in systems where several movements must occur simultaneously. When the valve is neutral, its open-center layout lets fluid pass freely between inlet and outlet, reducing strain on pumps and improving efficiency.

Because the SD11‑2S Electromagnetic control is engineered for clean fluid (≤10 µm) and wide viscosity range, it keeps internal wear low—especially when running mineral-based hydraulic oil. Plus, with tolerance to extreme temperatures, it’s ready for field use, both in hot summers and freezing winters.

Ideal Applications & Use Cases

Thanks to its performance and features, the SD11‑2S fits many hydraulic systems, such as:

• Earthmoving and construction machinery
• Mobile cranes and lifting gear
• Industrial presses and machine tools
• Agricultural equipment with remote controls
• Material handling systems

Wherever fast, reliable, solenoid-operated hydraulic control is needed, the SD11‑2S brings that capability to your design.

Installation, Maintenance & Safety Tips

To get the most from your SD11‑2S Electromagnetic control valve:

1. Use proper filtration (10 µm or finer) to prevent abrasive particles from damaging internal parts.
2. Ensure power supply to the solenoid is stable and meets specifications—unstable power can cause mis-actuation.
3. Protect from extreme shocks or vibrations; mount solidly to avoid wiring or internal damage.
4. Check fluid viscosity and temperature conditions to stay within allowed ranges (15–400 mm²/s, –40 °C to +80 °C).
5. Use compatible hydraulic oil, preferably mineral-based, to maintain seal integrity and performance.

Routine inspection of seals, connectors, and solenoid coils will keep the valve functioning reliably over many cycles.
