What is a pneumatic solenoid valve?

Pneumatic solenoid valve is a type of standard electromechanical solenoid, which, when activated by electricity, opens the valve under positive or negative air pressure. In standard industrial applications, they have been used as a type of switching on/off for for many years for pneumatic -powered systems, such as air drills. They are also commonly used in fluid control systems, such as for the release of hot and cold water into the washing bathtub in an automatic washing machine or for outdoor lawn sprinkler systems. It consists of a wire winding around a movable shaft, which is similar to the design of the engine. When the electrical energy passes through the winding, it creates a magnetic field that pushes on the shaft that acts as a form of the control of the controller to lower the switch, valve or other mechanical unit. The pneumatic solenoid valve varies from traditional, in that the controller controls the valve that is below a certain pressure level. Can either work to relaxKU and allow the flow of gas or liquid when electric current is applied, or the pressure itself can activate the valve in the opposite and create an electrical signal that is directed to the monitoring station.

Some pneumatic valve assemblies are also small control units that act as triggers for larger solenoids, and together these types of pneumatic solenoid valve design are often referred to as a pilot valve or a compressed air pilot valve. Pilot valves can be stackable, which means that they can be arranged in a series for pipes or other assembly of fluid or gas flow so that pressure and flow can be directed to key points in the industrial process. The only pneumatic solenoid valve that is installed as a pilot valve often also has a manual control level of control. This means solenoid function of the unit where the driver opens and closesThe valve can be operated manually by pressing the button or moving the mechanical arm. In more sophisticated industrial systems, however, the pilot valve unit is electrically controlled by a number of programmable settings for running power to solenoid, if necessary to open or close the valve.

In automated industrial systems where there are a large number of inaccessible pipes that must be controlled remotely, pneumatic solenoid valve systems are often selected because they can be operated by the ambient pressure that is built in the system itself and does not require external performance. This allows them to act as a type of safety valve to release pressure if necessary, and in the process mechanical movement of pressure release can activate the electromechanical feature of solenoid so that the short electrical signal is transferred to the control station to change the valve status. Ghoj, also serve a reverse function where they can be opened or closed from the control station if the operator determines that the systemdoes not perform correctly.

Parts

solenoid valve parts can range from very small units for fast, micro-control systems where they have a diameter of 0.4 inches (10 millimeters) and can be performed at low-level direct current (DC) voltage of 12 volts. High performance industrial valves at the opposite end of the spectrum are made of strengthened steel alloys. They can handle pressures of up to £ 4,500 per square inch (316 kilograms of centimeters to the other) and temperatures up to £ 1,200 ° Fahrenheita (649 ° Celsius).

types of solenoids used in electromechanical systems differ greatly depending on the needs of the system. The pneumatic solenoid valve can control multiple input and output ports with complexity in the range up to 5/3 of the air valve. 5/3 Pneumatic solenoid valve has 2 exhaust ports to control gas or liquids out, 2 power ports that serve as special action members of the system, and 1 supply port for input gas or fluid pressure. TowerHowever, a number of pneumatic solenoids are based on a 2/2 design, with an input port, an outlet port and a pilot port that serves as a shift mechanism to fully open or close the system. Depending on the needs of the machinery, the pneumatic solenoid valve is designed with normally open (not) or normally closed (NC) latent condition that keeps against pressure if no energy is applied to it.
