Solenoid Valve Application Tip

Solenoid Valve Application Tip
A solenoid valve performs as an electromechanical device via the valve's coil, which forms a magnetic field that is used to control the movement of tools and systems driven by liquids or gases. It is used to regulate the shutdown, discharge, capacity adjustment or mix fluids and gases. Solenoid valves offer switching free of risks and escalate reliability with long service life. Excellent compatibility with materials and resourceful design.

When applying a solenoid valve, check the response time and valve length. To turn cycling on and off, it is recommended that you select a non-stop full service valve to withstand constantly used pressures. Compare all functions to select the correct type of solenoid valve. The maximum operating pressure that can be tolerated must be greater than the pressure required to operate the valve.
The following are some considerations when selecting a solenoid valve.
Check the type of valve to be used
Pilot Operated Valves - This type of valve comes with a pilot and main valve seat, and the valve top is made from a pilot seat with a corresponding hole. Pilot-operated valves require less power to operate, but require full power to open and open.
Direct acting valves - This type of valve operates correctly according to the active current level of the coil. The valve supports the flow and pressure of the liquid or gas and opens and closes as long as the maximum available pressure is not exceeded.
· Bidirectional valve - The valve port is used interchangeably to activate valve opening and closing. This can be shown as a normally open valve or a normally closed valve. Normally, a closed solenoid valve is normally used and will remain idle until the active source is open.
· Three-way valves - Three-way valves have three ports and two holes, one of which is open and the other statics are always closed. These valves are applied alternately to de-pressurize and display in three normally closed, normally open, or general-purpose conditions.
· Four-way valve - This valve has four doors. It is displayed as normally open or as universally closed. This type of valve is usually used with two operating cylinders or two actuators. Two of the ports of this valve apply pressure and the other two release pressure.
Power necessities
The voltage or power required can help you choose the right type of solenoid valve for your application. However, since the flow is limited by the valve bore, large orifices tend to use more force. For example, if high flow rates and low energies are required, pilot operated valves should be used because they are best suited for this type of power requirement.
Flow share
Define the flow rate required by your application to properly select the solenoid valve. Be sure to know how much flow is required if the valve is too large because the fluid / air and money are wasted and the valve is too large. If it is too small, the actuator will not work properly.
Electrical connector
How is the solenoid valve connected to the pneumatic circuit? Whether you choose a knife connector or a fly lead, it depends on your personal preference. Both are easy to install, but choosing both together simplifies the valve replacement required.
Working pressure
Review the operating pressure indicated by the valve manufacturer. Operating pressure has a significant effect on the valve flow rate, so determining the operating pressure will help you to select which valve to operate as needed for your application.
Door size
Check the door size of the base or manifold so that you can purchase the correct valve fitting. The solenoid valve must be installed in a single base manifold or multiple stations to allow air to enter the circuit. Depending on your application, select the appropriate connection and connect the pipeline to ensure that the valve is in place.
