What is the difference between a fail open valve and a fail closed valve?
Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.
Hydraulic directional valves what is the difference bet open center and closed center?
A close center directional valve holds the position of the cylinder. This is because in its center position its 4 ports (4/3 way) are blocked. An open center valve on the other hand does not hold position in the center position. This valve is commonly used for motors because it handles system overloads or "shocks" to the system. All 4 ports are connected in the form of an H. This valve is sometimes called an H-mid position valve. I hope this answered your question.

When do you know that a hcr valve is open?
You can determine that a high-pressure relief (HCR) valve is open when you observe a noticeable drop in system pressure, often accompanied by a flow of fluid or gas discharging from the valve outlet. Additionally, many HCR valves have visual indicators or gauges that show whether the valve is in an open or closed position. If the valve is equipped with an audible alarm or signal, activation of this feature can also indicate that the valve is open. Regular maintenance checks and testing can help confirm the valve's operational status.
How do you know if on a water pipe is open or closed a valve is closed?
To determine if a valve on a water pipe is open or closed, you can usually inspect the valve handle's position. If the handle is parallel to the pipe, the valve is typically open, allowing water flow. Conversely, if the handle is perpendicular to the pipe, the valve is closed, blocking the flow. Additionally, listening for water flow or checking for pressure changes can provide further confirmation.
