Solenoid valves are the most common component in pneumatic systems given that they control actuation and/or its direction. There are some frequently asked questions that our clients ask about solenoid valves:
Metallic vs Plastic Solenoid Valves
Solenoid valves from, Univer (AC-series) or Metal Work, for example, can be composed of a metallic chasis (zinc, alumnium, and the like), which allows for greater reliability and robustness. On the other hand, plastic variants such as those from Mindman (MVSC Series) present ultimate economy with reliability almost just as good. In some circumstances, solenoid valve weight also plays a role in which case plastic solenoid valves are necessary.
Spool vs Poppet vs Rotary Solenoid Valves
By definition, solenoid valves, for pneumatic use, have a solenoid coil which when electrilised effects some consequence. The consequence varies between the different types of solenoid valve constructions: Spool, Poppet and Rotary. In the case of Spool valves, when the coil is electrilised, a magnetic field is produced and the internal spool physically moves within the valve body, and thereby changing paths in which compressed air can flow.
A poppet solenoid valve works in a similar fashion. However, instead of a spool, a poppet (usually a metallic ball) changes position, thereby changing the airways. There are some critical differences that are important to be aware of for different applications. Read more...
Solenoid Valve Voltage
The most common voltages for solenoid valves are DC24v, AC110v, AC220v, and the other possible voltages being DC12v and AC24v. Each voltage has their advantages and disadvantages.
To setup a pneumatic system to be used with DC (direct current) supply is more costly than AC (alternating current) supply. This is because the operating current of DC supply is higher than that of AC supply, and procedures must be in place to preclude voltage drops on the return line. Read more...
