Rexroth solenoid valve selection should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, it should be based on six aspects of the on-site working conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements).

Rexroth Solenoid Valve Selection Basis:

1. Selecting the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection method

1) Determine the nominal diameter (DN) according to the on-site pipeline inner diameter or flow rate requirements;

2) Connection method: Generally, >DN50 requires a flange connection; ≤DN50 can be freely selected according to user needs.

2. Selecting Solenoid Valves Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves 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 are preferred.

3) Fluid state: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN25, these must be clearly distinguished.

4) Fluid viscosity: Generally, any viscosity can be selected below 50 cSt. If it exceeds this value, a high-viscosity solenoid valve should be selected.

3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structural Types

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is 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 valve must be selected; when the minimum working pressure difference is above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected. 4. Electrical Selection: AC220V or DC24V voltage specifications are preferred for ease of use.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the duration 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, a continuously energized type cannot be selected; a type that can be continuously energized should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, Check Valve, Manual Operation, Water-resistant (fogproof), Water Spray, Submersible.

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. They are 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, while ensuring control accuracy and flexibility. There are many types of solenoid valves, each playing a different role in a control system. The most common types include check valves, safety valves, directional control valves, and speed control valves.

Rexroth is committed to providing safe, precise, efficient, and cost-effective drive and control technologies for various machines and systems.
