Main features of SMC solenoid valves

1. Main features of SMC solenoid valves: Solenoid valves eliminate external leakage, easily control internal leakage, and are safe to use. Internal and external leakage are factors that endanger safety. Other self-control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by electric, pneumatic, or hydraulic actuators. This requires solving the problem of external leakage of the dynamic seal of the valve stem during long-term operation; only solenoid valves use electromagnetic force to act on the iron core sealed in the magnetic sleeve of the electric regulating valve, which does not have a dynamic seal and easily eliminates external leakage. [1]

2. Electric valves are difficult to control torque and are prone to internal leakage, even breaking the valve stem head; the structure of solenoid valves makes it easy to control internal leakage, even reducing it to zero. 1. Solenoid valves are exceptionally safe to use, especially suitable for corrosive, toxic, or high/low temperature media.

2. SMC solenoid valve systems are simple, easy to connect to computers, and inexpensive. The solenoid valve itself has a simple structure and low price, making it easier to install and maintain than other types of actuators such as control valves. More significantly, the resulting automatic control system is much simpler and cheaper.

3. Because solenoid valves are controlled by on/off signals, they are very easy to connect to industrial control computers. In today's era of widespread computer use and significantly reduced prices, the advantages of solenoid valves are even more pronounced. SMC solenoid valves offer rapid action, low power consumption, and a compact design.

The response time of solenoid valves can be as short as a few milliseconds; even pilot-operated solenoid valves can be controlled within tens of milliseconds. Due to their self-contained circuit, they are more responsive than other automatic control valves.

4. Well-designed solenoid valve coils consume very little power, making them energy-saving products; they can also be designed to automatically maintain the valve position only after triggering, consuming no power under normal conditions. Solenoid valves are small in size, saving space and are lightweight and aesthetically pleasing. However, the adjustment accuracy and applicable media of solenoid valves are limited.

6. Solenoid valves typically only have two states: on and off. The valve core can only be in two extreme positions, preventing continuous adjustment (although many innovative designs are attempting to overcome this limitation, they are still in the experimental stage). Adjustment precision is also somewhat limited.

7. SMC solenoid valves have high requirements for media cleanliness. Media containing particulate matter are unsuitable; impurities must be filtered out first. Furthermore, viscous media are unsuitable, and certain products have a relatively narrow applicable viscosity range.

8. SMC solenoid valves come in various models and have wide applications. Although solenoid valves have inherent limitations, their advantages are still very prominent, allowing for the design of a wide variety of products to meet diverse needs and making them extremely versatile. Advances in solenoid valve technology have all focused on overcoming these inherent limitations and better leveraging their inherent advantages. SMC Solenoid Valves (Japan)

SMC Solenoid Valve Selection Principles (Japan)

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, copper alloy valves are also recommended; otherwise, rust particles will frequently fall from the valve body, especially in infrequent applications. Copper valves cannot be used for ammonia.

2. Explosive Atmospheres: Products with the appropriate explosion-proof rating 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 pipeline.

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

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 these limits, voltage stabilization measures must be taken.

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