A Rexroth solenoid valve has a sealed chamber with through-holes at different positions, 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. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn 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. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and 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 freely selected according to user needs. 2. Selection of Solenoid Valves Based on Fluid Parameters: Material, 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 should be chosen;

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN25, which must be clearly distinguished;

4) Fluid Viscosity: Generally, any choice is acceptable below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected. 3. Selection of Solenoid Valves Based on Pressure Parameters: Principle and Structural Types

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; 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: For voltage specifications, AC220V and DC24V should be prioritized for convenience. 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, normally open types cannot be selected; continuously energized types should be chosen.

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

1. Selecting Solenoid Valves 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) Connection type: Generally, for DN > 50, a flange connection should be selected; for DN ≤ 50, the connection type can be freely selected according to user needs.

2. Selecting Solenoid Valves Based on Fluid Parameters: Material, 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 should be chosen.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN 25, it is essential to distinguish between these states.

4) Fluid Viscosity: Generally, any choice is acceptable below 50 cSt; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3.
