ONE QUARTER 1/4 TURN Oxygen FULLY open I strongly suggest you take the AWS safety course if you ask this kind of question as you may end up killing some innocent because of your dangerous actions
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
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.
The handle faces the direction of flow

No. Gate valves are designed to be either completely open or completely closed. Regulating flow is best done with a globe or plug valve, or certain kinds of ball valves. A gate valve left partially open will eventually wear down so that it can never be completely closed.
To open an acetylene cylinder valve, you should turn the valve slowly and carefully in a counterclockwise direction. Always ensure that you are using the correct regulator and that the cylinder is in an upright position, secured, and away from any ignition sources. Additionally, it's important to check for leaks with soapy water before use and to wear appropriate personal protective equipment. Never open the valve fully; just open it enough to allow the desired flow of gas.
No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
The saddle valve is open.
To determine if a valve is open or closed, you can visually inspect the position of the valve handle or lever. If the handle is parallel to the pipe, the valve is open. If the handle is perpendicular to the pipe, the valve is closed.
A thermopile generates electricity from the heat of a pilot light. It generates about 750 mV that turns on the main gas valve to the fireplace.A thermocouple is heated by the pilot light but it uses pressure to hold the pilot light gas supply valve open. When the thermocouple is heated, pressure increases holding open the main gas valve. If it cools down, the pressure goes down and closes the gas valve.
To open the tank valve on an oxygen cylinder, make sure the regulator is attached securely. Slowly turn the valve counterclockwise until it is fully open. Always open the valve slowly to prevent damage to the regulator or sudden release of high-pressure gas.
To manually open a sprinkler valve, locate the valve box and remove the lid. Turn the solenoid counterclockwise to open the valve manually. Be sure to turn it back clockwise to close the valve once you are done.
To open a water valve, turn the handle or lever in a clockwise direction until it is fully open.
The gas valve is closed.
To determine if a pool valve is open or closed, check the position of the valve handle. Typically, a valve handle that is aligned with the pipe indicates it is open, while a handle that is perpendicular to the pipe signifies it is closed. Additionally, you can observe the flow of water; if water is flowing through the system, the valve is likely open. In contrast, if there is no flow or pressure, the valve may be closed.
the cam shaft belongs to the engine timing system A camshaft is used to open valves at specific points on the piston travel back and forth in the cylinder, so the camshaft is syrchronized with the crankshaft, and is also driven by the crankshaft. A camshaft is a steel rod with cams on it, and cams are metal parts that are in the form of a circle which has been pulled out on one side. When the cam turns against the valve, or pushrod, in some cases, the pulled out part pushes the valve open. After it turns a bit, it is no longer pulled out of the circular shape, and the valve closes. Cams vary by the duration of the time that they will hold the valve open. High performance cams hold valves open longer, in most cases, to allow the engine to breathe better, drawing more fuel, and exhuasting the spent fuel longer.
