Why 24V Solenoid Systems Dominate Industrial Hydraulics

In today’s fast-changing world of industrial hydraulics, picking the right control voltage matters more than ever. Factories and mobile machines head toward greater automation, so many system builders now prefer 24V solenoid systems over older AC setups. At KYDAC, we have worked in hydraulic research and manufacturing for more than 24 years. We have seen how 24V DC systems bring better safety, steady performance, and accurate control. Our components follow these current standards and help companies run more smoothly with fewer stops in production.

The Technical Superiority of 24V DC over AC Systems

The move to 24V DC comes from clear gains in safety and how long parts last.

Enhanced Safety and Reduced Electrical Risk

Low-voltage DC setups create a much safer workplace for workers and technicians than high-voltage AC ones.

• By running at 24V, the chance of serious electric shock drops almost to zero. This matters a lot in damp or shaky industrial settings.
• DC systems make emergency stops simpler and fit more easily with modern safety PLCs and low-voltage circuits.
• They avoid the sudden voltage spikes common in AC coils. This cuts wear on contacts and stops noise that could affect nearby sensors.

Thermal Management and Solenoid Longevity

Keeping temperatures steady helps hydraulic systems run without breaks in tough factory conditions.

• 24V DC solenoids produce even magnetic pull without the buzzing or shaking that AC coils often cause. This leads to less strain on moving parts.
• KYDAC’s 24V systems manage heat better and stop oil from getting too hot, which protects seals and helps components last longer.
• The steady power use in DC setups gives more reliable valve action, so they keep switching well even after many thousands of operations.

KYDAC’s 24V Solenoid Product Portfolio: Engineering Excellence

At KYDAC, we build products that go beyond basic requirements through careful production and strong materials.

The 4WE6 and 4WE10 Series: High Flow and Pressure Capabilities

Our main directional valves manage heavy hydraulic work while staying compact.

• The 4WE6 series handles a rated flow of 80 L/min and works under pressures up to 35 MPa. It serves as a reliable choice for medium equipment.
• The 4WE10 series pushes flow up to 120 L/min for bigger demands. This supports quicker movements and higher output in heavy machines.
• Both lines use solid cast iron bodies that hold shape well and feature precise spools for smooth direction changes.

Explosion-Proof Reliability: The GD-4WE6E-DC24V Advantage

Safety comes first in places with gases or dust that could ignite.

• The GD-4WE6E-DC24V is a special solenoid directional valve with built-in explosion protection.
• It runs on 24V DC power and fits safely into electrical systems on mining excavators or chemical spraying gear.
• This model stops sparks from causing fires while still managing 31.5 MPa pressure and 80 L/min flow.

How 24V Solenoid Systems Solve Tough Performance Challenges in the Field

Knowing exactly how and where these valves work helps match them to different industries.

Precision Control in Heavy Construction Machinery

Big construction jobs need machines that handle multiple movements smoothly and without delay.

• In 400-ton hydraulic excavators, KYDAC’s 24V solenoid valves, like the 4WE10 series, control the boom, arm, and bucket.
• Their quick response, with switching under 100ms, lets operators perform digging and leveling moves accurately.
• The 24V DC power connects directly to onboard batteries and removes the need for extra power converters.

Automated Production Lines and Robotics

In automated factories, speed and consistent results decide success.

• Production lines use our EMC series electromagnetic multi-way valves to manage several hydraulic cylinders from one PLC signal.
• These 24V systems cut down on complicated piping and take up over 50% less space than scattered control setups.
• On robotic lines, the fast action of KYDAC solenoids supports quick pick, place, and clamp tasks.

Harsh Environments: Mining and Oil & Gas

Gear that works underground or at sea deals with pressure, moisture, and corrosion every day.

• Our 24V solenoid systems, especially stainless steel versions of the 4WE series, resist corrosion in chemical plants and coastal areas.
• In oil and gas service equipment, the GD series explosion-proof valves protect people and machines from ignition dangers.
• These units run well from -40°C to +80°C, covering cold northern winters and hot desert mining conditions.

Simplified Industrial Layouts and Integration

Good industrial design means fewer complications and parts that are easy to get and service.

Interchangeability and Global Standards

KYDAC valves make upgrades straightforward for plants with existing equipment.

• Our 24V solenoid valves match dimensions and performance with models from major brands like Rexroth, Yuken, and Vickers.
• This compatibility keeps maintenance costs down and avoids long waits for spare parts that could halt operations.
• Following ISO 4401 mounting standards lets our valves drop into current setups with few changes.

Reducing System Complexity with Integrated Valve Groups

Today’s hydraulic designs favor combined units instead of many separate valves that might leak.

• The KYDAC EMC series packs up to 12 control channels into one compact body. This cuts outside connections and possible leak spots.
• For dual-pump setups, our Double Pump Valve Group series applies 24V logic to combine or separate flows as needed and can lower energy use by up to 25%.
• The approach simplifies the main control area on vehicles like silage balers or sanitation trucks, so daily checks and repairs stay easy.
