Product Description:

SD11‑2S Electromagnetic Control Valve – High-Flow Solenoid Directional Control

Advanced Solenoid-Driven Hydraulic Control

The SD11‑2S Electromagnetic control valve is built for applications where fast, reliable, and remote hydraulic actuation is essential. With a maximum flow rate of 70 L/min and pressure handling up to 315 bar, this directional control valve delivers strong performance in demanding hydraulic systems. Electromagnetic operation (solenoid actuation) enables precision switching without manual linkages, making it ideal for automated machinery, industrial equipment, and remote-controlled systems.

Key Specifications & Features

Engineered with care, the SD11‑2S Electromagnetic control valve offers the following attributes:

• Flow & Pressure: Handles 60–70 L/min (approx. 16 GPM) with a maximum rating of 315 bar (31.5 MPa).
• Port Connections: P, A, B are G1/2 BSP; tank (T) port is G3/4. Pressure connection is 3/8″.
• Dimensions & Weight: Measures 28 × 24 × 10.5 cm and weighs 12.7 kg.
• Valve Type: Four-way directional flow, in a solenoid-controlled configuration.
• Oil Circuit & Flow: Parallel circuit design. Includes open-center path, allowing fluid from side inlet to pass through to side outlet when the valve is neutral.
• Filtration & Fluid Compatibility: Requires ≤10 µm filtration. Works with mineral-based hydraulic oils. Supports fluid viscosity of 15–400 mm²/s.
• Temperature Tolerance: Operates smoothly between –40 °C and +80 °C.
• Construction: Tube-structure housing, built for long-term use and consistent performance.
• Warranty & Origin: One-year warranty. Made by Hy-Waloil, located in Jiangsu, China.

These features ensure the valve performs reliably across varying operating conditions while providing responsive electromagnetic control.

How It Works & Why It Matters

With the SD11‑2S Electromagnetic control valve, solenoid coils convert electrical signals into mechanical movement, shifting the spool and routing hydraulic flow. Because this happens electrically, operators can trigger control functions remotely or integrate the valve into automated systems without physical levers or cables.

Importantly, the open-center design means that when the valve isn’t actuated, fluid flows from the inlet to the outlet with minimal resistance. This reduces pump pressure load and enhances system efficiency during idle periods.

Thanks to the parallel circuit layout, each actuator linked to the valve can operate independently, allowing multiple movements simultaneously. This is critical for machines that require coordinated actions, such as grabbing, lifting, rotating, and tilting.

Because the valve tolerates a wide fluid viscosity range and has a high-grade filtration requirement (≤10 µm), it resists internal wear and maintains predictable operation over many cycles.

Applications & Use Cases

The SD11‑2S Electromagnetic control valve is ideal wherever quick, controlled hydraulic flow is necessary:

• Construction machinery – controlling booms, buckets, jibs, or attachments
• Industrial presses or stamping machines – remote switching
• Agricultural equipment – automated hydraulic functions
• Material handling and lifting systems – cranes, lifts, rotators
• Mobile hydraulics – in remote or unmanned systems

Its strong pressure and flow specs, combined with solenoid actuation, make the valve suitable for both heavy-duty and precise control tasks.

Installation Tips & Maintenance Guidance

To leverage the SD11‑2S Electromagnetic control valve reliably:

1. Use clean hydraulic fluid with ≤10 µm filtration to prevent internal damage.
2. Supply stable electrical power to solenoids—voltage drops or spikes may cause mis-actuation.
3. Mount securely to minimize vibration and protect wiring.
4. Monitor fluid viscosity and temperature to stay within 15–400 mm²/s and –40 °C to +80 °C ranges.
5. Inspect seals and wiring periodically, especially in harsh environments or heavy use cycles.

By following these best practices, the valve will maintain consistent performance and longevity.
