Selection principles for MAC solenoid valves

Selection principles for MAC solenoid valves

MAC Valves, founded in 1948, has over 70 technologies in the field of solenoid valve technology and specializes in designing and manufacturing high-performance air pressure solenoid valves. MAC focuses on providing customers with solenoid valves, which are known for their compact structure, high repeatability, and easy maintenance. MAC solenoid valves currently hold 26% of the market in the United States and are widely used in packaging machinery, tire machinery, mining, automotive industry, electronics industry, aluminum products industry, wood industry, paper industry, printing industry, food industry, and beverage industry. The main products of MAC company include MAC solenoid valves, MAC proportional valves, MAC servo valves, MAC regulating valves, MAC pneumatic valves, MAC electromagnetic directional valves, MAC electromagnetic control valves, etc. Here are the MAC, American MAC valves, and MAC solenoid valves that we introduce to you

Selection principles for MAC solenoid valves

Safety of MAC solenoid valve:

1. Corrosive media: Plastic king solenoid valves and all stainless steel should be selected; For strongly corrosive media, isolation membrane type must be selected. Neutral media, it is also advisable to use copper alloy as the valve shell material for solenoid valves, otherwise rust debris often falls off from the valve shell, especially in situations where the action is not frequent. Ammonia valves cannot use copper materials.

2. Explosive environment: Corresponding explosion-proof products must be selected, and waterproof and dustproof varieties should be selected for outdoor installation or in dusty environments.

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

Applicability of MAC solenoid valve:

1. Medium characteristics

1) Select different types of solenoid valves for gas, liquid, or mixed states;

2) Products with different specifications and medium temperatures may cause the coil to burn out and the sealing components to age, seriously affecting their service life;

3) The viscosity of the medium is usually below 50cSt. If it exceeds this value and the diameter is greater than 15mm, use a multifunctional solenoid valve; When the diameter is less than 15mm, use a high viscosity solenoid valve.

4) When the cleanliness of the medium is not high, a backwash filter valve should be installed in front of the solenoid valve. When the pressure is low, a direct acting diaphragm solenoid valve can be selected;

5) If the medium flows in a directional manner and backflow is not allowed, it needs to flow in both directions;

6) The medium temperature should be selected within the allowable range of the solenoid valve.

2. MAC solenoid valve pipeline parameters

1) Select valve ports and models based on the requirements of medium flow direction and pipeline connection method;

2) Select the nominal diameter based on the flow rate and valve Kv value, or choose the same pipe inner diameter;

3) Working pressure difference: Indirect pilot type can be selected for working pressure difference above 0.04Mpa; If the working pressure difference is close to or less than zero, direct action or step-by-step direct action must be selected.

3. MAC solenoid valve environmental conditions

1) The maximum and temperature of the environment should be selected within the allowable range;

2) In environments with high relative humidity and water droplets and rain, waterproof solenoid valves should be selected;

3) Special varieties should be selected for situations where there are frequent vibrations, bumps, and impacts in the environment, such as marine solenoid valves;

4) The use in corrosive or explosive environments should prioritize the selection of corrosion-resistant types according to safety requirements;

5) If the environmental space is limited, a multifunctional solenoid valve should be selected because it eliminates the need for a bypass and three manual valves, and is easy to maintain online.

4. MAC solenoid valve power supply conditions

1) Select AC and DC solenoid valves according to the type of power supply. Generally speaking, AC power supply is easy to access;

2) Voltage specifications should prioritize AC220V and DC24V as much as possible;

3) The fluctuation of power supply voltage is usually selected as+% 10% AC -15%, DC allowable ±% 10, if exceeding the tolerance, voltage stabilization measures must be taken;

4) The rated current and power consumption should be selected based on the power capacity. Attention should be paid to the high VA value during communication start-up, and indirect induction solenoid valves should be preferred when the capacity is insufficient.

5. Control accuracy of MAC solenoid valve

1) Ordinary solenoid valves only have two positions, on and off. When high control accuracy and stable parameter requirements are needed, multi position solenoid valves should be selected;

2) Action time: refers to the time from when the electrical signal is turned on or off to when the main valve action is completed;

3) Leakage rate: The leakage rate values given on the sample are commonly used economic levels.

Reliability of MAC solenoid valve:

1. The working life is not included in the factory test items, but belongs to the type test items. To ensure quality, products from reputable manufacturers should be selected.

2. Work system: divided into three types: long-term work system, repeated short-term work system, and short-term work system. For situations where the valve is open for a long time but only closed for a short time, it is advisable to use a normally open solenoid valve.

3. Working frequency: When the operating frequency requirement is high, the structure should preferably use a direct acting solenoid valve, and the power supply should preferably use AC.

4. Action reliability

Strictly speaking, this test has not yet been officially included in the professional standards of Chinese solenoid valves. To ensure quality, products from reputable manufacturers should be selected. In some situations where the number of actions is not high, but the reliability requirements are very high, such as fire protection, emergency protection, etc., we must not take it lightly. It is particularly important to adopt dual insurance for two consecutive uses.

Economy:

It is one of the selected scales, but it must be economical based on safety, applicability, and reliability.

Economy is not only about the price of the product, but also about prioritizing its functionality and quality, as well as the cost of installation, maintenance, and other accessories.

More importantly, the cost of a single solenoid valve in the entire control system and even in the production line is negligible. If one chooses the wrong one for the sake of small gains, it can cause huge damage to the group.
