FESTO

Solenoid Valve JMFH-5-3/8-B; 19700

FESTO solenoid valves are used until major components fail, preventing normal switching and reset actions, or until their main performance indicators significantly deteriorate beyond the specified number of switching cycles.

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

FESTO Solenoid Valve Selection Criteria:

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

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

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 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 types cannot be selected; continuously energized types should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, check valve, manual operation, waterproof mist, water spray, submersible.

FESTO Solenoid Valve Selection Principles

Safety:

1. Corrosive Media: Plastic-coated solenoid valves and all-stainless steel valves are recommended. For highly corrosive media, diaphragm-type valves must be selected. For neutral media, solenoid valves with copper alloy valve bodies are also recommended; otherwise, rust particles will often fall from the valve body, especially in applications with infrequent operation. 1. Copper cannot be used for ammonia valves.

2. Explosive environments: Appropriate explosion-proof products must be selected. For outdoor installations or dusty environments, waterproof and dustproof models should be selected.

3. The nominal pressure of the solenoid valve should exceed the maximum working pressure in the pipe.

Applicability:

1. Media characteristics

1) Different types of solenoid valves should be selected for gaseous, liquid, or mixed states.

2) Different specifications of products should be used for different media temperatures; otherwise, the coil will burn out, the seals will age, and the lifespan will be severely affected.

3) Media viscosity is usually below 50 cSt. If it exceeds this value, a multi-functional solenoid valve should be used when the pipe diameter is greater than 15mm; a high-viscosity solenoid valve should be used when the pipe diameter is less than 15mm.

4) When the media cleanliness is not high, a backflush filter valve should be installed before the solenoid valve. For low pressure, a direct-acting diaphragm solenoid valve can be selected.

5) If the media flows in a directional manner and backflow is not allowed, a bidirectional flow valve is required.

6) The media temperature should be selected within the allowable range of the solenoid valve. 2. Piping Parameters

1) Select the valve port and model according to the medium flow direction requirements and pipeline connection method;

2) Select the nominal diameter according to the flow rate and valve Kv value, or select the same as the pipeline inner diameter;

3) Working pressure difference: For a minimum working pressure difference above 0.04 MPa, an indirect pilot-operated valve can be selected; for a minimum working pressure difference close to or less than zero, a direct-acting or step-by-step direct-acting valve must be selected.

3. Environmental Conditions

1) The maximum and minimum ambient temperatures should be within the allowable range;

2) In environments with high relative humidity or water droplets/rain, a waterproof solenoid valve should be selected;

3) In environments with frequent vibration, bumps, and impacts, a special type should be selected, such as a marine solenoid valve;

4) In corrosive or explosive environments, corrosion-resistant types should be selected based on safety requirements;

5) If space is limited, a multi-functional solenoid valve should be selected, as it eliminates the need for a bypass and three manual valves and facilitates online maintenance. 4. Power Supply Requirements

1) Select AC or DC solenoid valves according to the type of power supply. Generally, AC power is more readily available.

2) Prioritize AC220V or DC24V voltage specifications.

3) Power supply voltage fluctuations are typically +10% to -15% for AC and ±10% for DC. If these fluctuations exceed the tolerance, voltage stabilization measures must be taken.

4) Select the rated current and power consumption according to the power supply capacity. Note that AC has a higher VA value during startup; if the capacity is insufficient, indirect-acting solenoid valves should be preferred.

5. Control Accuracy

1) Ordinary solenoid valves only have open and closed positions. For high control accuracy and stable parameters, multi-position solenoid valves should be selected.

2) Activation Time: The time from the electrical signal being connected or disconnected to the main valve completing its action.

3) Leakage: The leakage values ​​given in the sample are for commonly used economic levels.
