Quotation for MAC solenoid valves in the United States

Quotation for MAC solenoid valve in the United States:Product Description: Like other solenoid valves, MAC solenoid valves are industrial equipment controlled by electromagnetic means. They are automation basic components used to control fluids and belong to actuators, not limited to hydraulic and pneumatic systems. It is used in industrial control system to adjust the direction, flow, speed and other parameters of medium. Electromagnetic valves can be used in conjunction with different circuits to achieve the desired control, while ensuring the accuracy and flexibility of the control.

Quotation for MAC solenoid valves in the United StatesWorking Principle:

The solenoid valve has a sealed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil on the other side is energized. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the oil cylinder, which in turn drives the piston rod, which drives the mechanical device. In this way, the mechanical motion is controlled by controlling the current on and off of the electromagnet.

The selection of solenoid valves should first follow the four principles of safety, reliability, applicability, and economy. Secondly, the selection should be based on six aspects of on-site conditions (i.e. pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action mode, and special requirements).

Quotation for MAC solenoid valves in the United StatesSelection criteria:

1、 Select the solenoid valve based on pipeline parameters: diameter specification (i.e. DN), interface method

1. Determine the diameter (DN) size according to the on-site pipeline inner diameter size or flow requirements.

2. Interface method, generally>DN50 requires flange interface, ≤ DN50 can be freely selected according to user needs.

2、 Select the material and temperature group of the solenoid valve based on fluid parameters

1. Corrosive fluids: corrosion-resistant solenoid valves and all stainless steel should be selected; Edible ultra clean fluid: It is recommended to use food grade stainless steel solenoid valves.

2. High temperature fluid: It is necessary to choose electromagnetic valves made of high-temperature resistant electrical materials and sealing materials, and to choose piston type structures.

3. Fluid state: ranging from gaseous, liquid or mixed state, especially when ordering with a diameter greater than DN25, it must be distinguished.

4. Fluid viscosity: Usually below 50cSt, it can be freely selected. If it exceeds this value, a high viscosity solenoid valve should be used.

3、 Selecting solenoid valves based on pressure parameters: principles and structural types

1. Nominal pressure: This parameter has the same meaning as other general valves and is determined based on the nominal pressure of the pipeline.

2. Work pressure: If the work pressure is low, the principle of direct action or step-by-step direct action must be selected; When the low working pressure difference is above 0.04Mpa, direct acting, step-by-step direct acting, and pilot operated can all be selected.

4、 Electrical selection: The voltage specifications should preferably be AC220V or DC24, which are more convenient.

5、 Choose based on the duration of continuous work: normally closed, normally open, or continuously powered on

1. When the solenoid valve needs to be opened for a long time and the duration is longer than the closing time, the normally open type should be selected.

2. If the opening time is short or the opening and closing time is not long, choose the normally closed type.

3. However, for some working conditions used for safety protection, such as furnace and kiln flame monitoring, the normally open type cannot be selected, and the long-term electrified type should be selected.

6、 Select auxiliary functions according to environmental requirements: explosion-proof, check, manual, waterproof fog, water shower, diving

1. Explosive environment: Electromagnetic valves with corresponding explosion-proof levels must be selected
