Selecting the appropriate valve for any application is imperative to ensure proper direction of flow, flow rate, exhaust function, and even basic valve functionality. In pneumatics there are so many terms for valves that it can seem overwhelming. Knowledge of valve function, porting, and actuation is key to obtaining the correct valve for the application.

What is hysteresis? Is it important for your application? What effects could it have? Generally speaking, hysteresis is a lag in reaction to a force. It can be found everywhere—from physics and engineering to biology, chemistry, and even economics. In this article, we explain the fundamentals and complexities as we explore how hysteresis affects the proportional control of fluids.
Every solenoid valve has a nominal actuation voltage, which is usually based on common power supply voltages such as 12 VDC, 24 VDC, 110 VAC, or 220 VAC. The nominal voltage is typically printed somewhere on the valve body or coil and is the voltage required to actuate (shift) the valve. Applying less than the nominal voltage will result in undervoltage and may result in a slower "on" response time or the valve not actuating at all.
It's no surprise that the cleaner your valve is, the less it will leak. However, cleanliness is also important in other ways, such as for medical applications where fluid flowing through the valves may be entering a person's body or for applications in the food and beverage industry. In these cases, the valves must not only be cleaned of any particulate matter, but also of any harmful substances used in the normal machining or assembly process.
To control flow without contaminating media such as blood, pharmaceuticals or reagents, a wide variety of medical devices and analytical equipment utilize media isolation valves. This article explores the characteristics of three main types of valves commonly used to isolate media.
