Rexroth Solenoid Valve 4WE10J3X/CG24N9K4+Z4 in Stock

Rexroth solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Commonly used types include check valves, safety valves, directional control valves, and speed control valves.

Rexroth is committed to providing safe, precise, efficient, and cost-effective transmission and control technologies for various machines and systems. The company integrates global application experience to develop innovative products, providing customized system solutions and services for customers in every segment of the mobile machinery, mechanical applications and engineering, factory automation, and renewable energy markets. Bosch Rexroth also provides customers with a wide range of hydraulic, electronic drive and control, pneumatic, gear, linear drive, and assembly technologies. The company operates in more than 80 countries worldwide, employs over 37,500 professionals, and achieved global sales of nearly €6.5 billion in 2012.

A Rexroth solenoid valve has a sealed chamber with through-holes at different locations, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. Controlling the movement of the valve body opens or closes different drain holes, while the inlet hole is always open. Hydraulic oil enters different drain pipes, and the oil pressure pushes the piston in the cylinder. The piston then moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.

Rexroth Solenoid Valve Selection Criteria:

1. Selecting the solenoid valve based on pipeline parameters: Nominal diameter (DN), connection type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) For connection type, generally, >DN50 requires a flange connection; ≤DN50 can be selected freely according to user needs.

2. Selecting the solenoid valve based on fluid parameters: Material, temperature group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.

2) High-temperature fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves should be chosen.

3) Fluid state: Valves can be gaseous, liquid, or mixed, especially for diameters greater than DN25, which must be clearly distinguished.

4) Fluid viscosity: Generally, below 50 cSt, any valve can be selected; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.

2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.

4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.

5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected.

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open valves cannot be selected; a continuously energized type should be chosen. 6. Select auxiliary functions according to environmental requirements: explosion-proof, backflow preventer, manual operation, waterproof mist, water spray, and diving protection.
