Direct acting MAC solenoid valve technology and application

Direct acting MAC solenoid valve technology and application

The balanced lift valve design facilitates the use of the same valve at any port to achieve six functional connections to vacuum, pressure, or blockage. The pipeline is shown in the following figure.

The interchangeable function board between valve bodies allows for the selection of three normally closed or three normally open operations.

Direct acting solenoid valve is a type of solenoid valve that uses electromagnetic force to directly drive the valve core to achieve opening and closing control. It is suitable for vacuum, negative pressure, and zero pressure working conditions, with a conventional diameter not exceeding 25 millimeters. The device is divided into normally closed and normally open types. When the normally closed type is powered on, the electromagnetic coil generates magnetic force to open the valve, and when the power is off, the spring returns and closes; The working principle of normally open type is opposite [2-3] [5]. Its structure includes components such as valve body, valve stem, sealing part, and reset spring. By eliminating the back pressure of the valve stem, zero pressure starting is achieved, improving response speed

An internal or external pilot valve model used on solenoid valves for vacuum to 25 PSI main valve pressure.

Large check accumulator for air/spring return.

Serial connection: Modular valve bodies can be connected in series with dedicated screws, and the number of valve bodies can be increased or decreased as needed, with common inlet and outlet ports.

Seat connection: A structure in which the valve body is installed on a base that contains all interfaces.

Busbar: It is a common bottom plate with shared inlet and outlet ports, and valves can be installed in groups.

The interchangeable functional board between the valve body and the base allows for the selection of options suitable for 2-way or 3-way, normally closed or normally open operation. In a three-way application, a functional board is used for N.C. and N.O.

When "3-NC" is visible on the board, the function will be N.C. When "3-NO" is visible, the function will be N.O.

In bidirectional applications, two separate boards are used, one for N.C. and labeled as "2-NC"; The other is N.O., marked as "2-No".

Injecting lubricant into the rubber material can reduce friction without the need for further lubricant;

3-channel normally open or normally closed (solenoid valve or remote air).

Bidirectional (by blocking the exhaust port), normally open or normally closed (solenoid valve or remote air).

It is a principle that combines direct action and pilot type. When there is no pressure difference between the inlet and outlet, after being energized, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward in sequence, and the valve opens. When the inlet and outlet reach the starting pressure difference, after being energized, the electromagnetic force pilot small valve, the lower chamber pressure of the main valve rises, and the upper chamber pressure drops, thereby using the pressure difference to push the main valve upwards; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing member downwards, causing the valve to close.
