About MAC Valves Inc. (USA):

MAC Valves was founded in January 1948 as Mechanical Air Control, with a capital of US$2,000. In 1962, the company name was changed to MAC Valves Inc.

Starting in 1964, MAC implemented an 18-month unconditional quality guarantee policy for all its products, printing this guarantee on its brochures and distributing them worldwide to emphasize the quality of MAC products. To date, no other manufacturer prints an 18-month quality guarantee on its brochures.

In 1971, MAC Valves Europe was established in Belgium, a branch of MAC Valves Inc.

In 1971, the Japanese government approved a manufacturing contract between MAC and SMC Corporation of Japan, under which MAC transferred technology to SMC and authorized SMC to produce solenoid valves in Japan. SMC also became MAC Valves' agent in the Asia-Pacific region. SMC was originally a filter manufacturer.

In 1972, MAC sold one million valves; five years later, sales doubled, exceeding two million by 1977.

In 1984, MAC Valves Pacific was established in New Zealand, a branch of MAC Valves responsible for sales and service in the Asian and Australian markets.

MAC Valves is an employee-owned company with over 1,300 employees worldwide.

Over the past six decades, MAC's technology in designing and developing equipment has successfully created highly competitive products with superior advantages for industrial automation applications.

MAC's material combinations are all proven through testing. This equipment provides testing of responsiveness and lifespan characteristics, making its ultra-high-speed performance among the best in the world.

Valve responsiveness, lifespan, and reliability have become standard requirements in manufacturing plants. Manufacturing valves with so many advantages requires advanced technology, but MAC has not neglected the importance of price.

MAC ultra-high-speed solenoid valves are competitive with other valves in the market.

MAC outsources sales and service to its worldwide network of agents, rather than directly selling its products.

Many features protect MAC's design capabilities, ensuring its expertise in pneumatic valve technology.

Here are some of the features of MAC's ultra-high-speed solenoid valves:

1. Coil burnout prevention.

2. Air and spring return ensure smooth and consistent valve response and prevent blockage.

3. Internal check accumulator design prevents valve tripping in case of insufficient air during operation.

4. Built-in shaft design with a larger open flow orifice provides a larger flow rate than usual.

5. Built-in dual shafts move within a single flow orifice, shortening the valve's stroke, resulting in less wear and longer lifespan.

MAC Valves currently holds a 26% market share in the United States, with 45% of its customers in packaging machinery, and the remainder in sorting machinery, tire machinery, mining, automotive, electronics, aluminum, timber, paper, printing, food, and beverage industries.

MAC Solenoid Valve Selection Criteria

The selection of MAC solenoid valves should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, it should 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).

MAC Solenoid Valve Selection Criteria:

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

1) Determine the nominal diameter (DN) based on the on-site pipeline inner diameter or flow requirement;

2) For the connection type, generally, >DN50 requires a flange connection, while ≤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 Type

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is determined based on 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 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.

MAC Solenoid Valve Selection Principles:

Safety:

1. Corrosive Media: Plastic King 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 working pressure difference above 0.04 MPa, an indirect pilot-operated type can be selected; for working pressure difference close to or less than zero, a direct-acting type or a step-by-step direct-acting type must be selected.

3. Environmental Conditions

1) The maximum ambient temperature 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 the environmental 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 Conditions

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

2) For voltage specifications, AC220V and DC24V should be preferred;

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

5. Control Accuracy

1) Ordinary solenoid valves only have two positions: open and closed. 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 grades.

Performance Requirements (Folded Edit Section)

1. Reversing Performance

Under specified operating conditions, can the solenoid valve reliably reverse direction after being energized and reliably reset after being de-energized? 2. Pressure Loss

The pressure loss of a solenoid directional valve consists of flow loss and throttling loss caused by fluid flowing through the valve orifice.

3. Internal Leakage

The internal leakage of a solenoid directional valve refers to the leakage from the high-pressure chamber to the low-pressure chamber under specified operating conditions and in various operating positions.

4. Switching and Reset Time

The switching and reset time is the time required from the energization of the solenoid to the termination of the valve core's switching. The reset time is the time required from the de-energization of the solenoid to the valve core returning to its initial position.

5. Reversing Frequency

Maximum number of reversals allowed per unit time
