Introduction to Major Products of MAC in the United States

1. American MAC valve

The MAC100 series is a three-way lift valve operated directly by electromagnetic means. It has a short stroke solenoid valve, a balance lift valve, and a reset spring. These characteristics translate into high shifting force, fast and consistent response time, and long lifespan. Their balanced design means the versatility of the pipeline - valves can be configured as 3-way or 2-way - normally closed or first open, or can be used for vacuum, splitter, or selector applications. The MAC 1100 series is a multifunctional three-way mechanical operated valve. This series has multiple manual operation options, ranging from levers and buttons to cam and remote pneumatic versions.

2. MAC liquid valve in the United States

Bullet Valve？ The BV series products represent another evolution of MAC valve technology. The Bullet Valve @ series products adopt MAC's Bullet technology. The advantage of this' boost 'solenoid valve configuration lies in the valve's balanced design, which is a signature feature of MAC valves. Therefore, despite fluctuations in inlet pressure, the shifting force remains high and the response time is more reproducible. Bullet Valve @ is available in 2-way, 3-way, and 4-way configurations. Their balanced design means the versatility of the pipeline - valves can be configured as 3-way or 2-way - normally closed or normally open, or can be used for vacuum, splitter, or selector applications.

3. American MAC pulse valve

The MAC liquid valve series products benefit from many of the same innovative features and related advantages, which have become synonymous with MAC performance characteristics over the years. Fast response time, reliable shifting force, and repeatable results are just some of the advantages you can gain from their fluid product line. Proportional flow control (PFC), flow valves, single and double diaphragm (medium separation) valves, wet solenoid valves, and metering fluid pumps are some of the products in the MAC liquid valve series. These valves are also suitable for pneumatic applications that require sealing performance. The MAC liquid valve series products are designed to have a longer service life and perform better in the most demanding applications. Compared to traditional valve technology, there are fewer wear points.

4. American MAC three-way valve

MAC pulse valves can be ordered in one of two pilot configurations: an integrated solenoid valve pilot combined with fast, repeatable pulses and manual operators, and their remote venting version can improve performance and reliability in hazardous locations. The main body of the MAC pulse valve adopts combined valve core technology, which has reliability beyond existing diaphragm technology. Check the accumulator and the main valve core with memory spring to ensure that it returns to its original position in case of possible air supply shortage. A series of adapter boards have also been released to directly insert and replace existing diaphragm pulse valves without interfering with existing pipelines.

Installation pipeline: It has both manual function and eliminates the need for three manual valves, allowing for online maintenance and greatly reducing costs.

1. The applicable range of medium viscosity can be adjusted: it can achieve universal use of gas, water, and oil, making it convenient for procurement, storage, installation, and maintenance.

2. The valve opening and closing time can be adjusted to meet various requirements and effectively prevent water hammer damage.

3. The valve opening can be adjusted: the maximum and minimum opening can be pre-set to improve the accuracy of automatic control.

4. The wear of the main valve can be compensated for: prolonging the service life of the valve and withstanding long-term tests. The structural principle of this valve cleverly combines the pilot MAC solenoid valve, manual valve, and throttle valve into one. The pilot valve receives an electrical signal switch and drives the main valve to operate. Adjusting screws A and B can adjust the applicable range of medium viscosity and the opening and closing time of the main valve, and can compensate for the wear of the main valve. When the pilot valve needs maintenance, simply tighten the adjusting screw B and isolation screw C to remove it, and manual screw operation can be used. This screw can also be used to preset the maximum or minimum flow rate for automatic control of MAC solenoid valves.

What are the working principles, classifications, and parameters of MAC solenoid valves?

When the MAC solenoid valve is laminar, the flow rate of the medium passing through the valve is linearly related to the pressure difference before and after the valve. In the mixed state of laminar and turbulent flow, as the Reynolds number increases, even if the pressure difference remains constant, the amount of medium flowing through the valve will also increase. In turbulent flow, the flow rate does not vary with changes in Reynolds number. However, the selection of small flow regulating valves is still carried out using traditional methods and calculation formulas. However, its calculated value deviates greatly from the actual value. According to data, when Cv is below 0.01, it is only used as a capacity indicator and has reference significance. The actual circulation capacity should be determined based on experience. As the flow capacity decreases, the adjustable ratio of the valve will decrease. But even a small amount can ensure a flow rate between 10:1 and 15:1. If the adjustable ratio is even smaller, it will be difficult to adjust the flow rate.

The commonly used valve seat aperture is 1/8 to 1/4 inch (approximately 3.17-6.35 millimeters), and the stem stroke of this type of valve is small, with a flow capacity of 0.00006 or even smaller. Generally speaking, cylindrical slotted valve cores are better in terms of characterization than conical ones. They can obtain design characteristics by changing the groove depth, but the latter has good adjustability because the fluid passing through the valve is distributed throughout the entire circumference of the valve core section. This type of valve is commonly used in situations where precision requirements are not very high. However, the accuracy of capacity and the reproducibility of characteristics are poor. The flow capacity of a valve mainly depends on the diameter of the flow hole. For a 1/16 inch flow hole, the theoretical Cv value is about 0.06, or only close to the upper limit of small flow rate. To further reduce the flow rate, it is necessary to fundamentally reduce the stroke of the valve core or constrain the opening of the flow hole.

The MAC solenoid valve ensures that the pressure difference before and after the valve is lower than the maximum allowable pressure difference for cavitation of the medium at the inlet temperature of the regulating valve. MAC flow regulating valves are mainly used in centralized heating (cooling) and other water systems to distribute pipe network flow according to demand, eliminate hydraulic imbalance in water systems, solve the problem of uneven heating and cooling, and can save energy and electricity by 15% -20%.
