Screw down non return valves only allow a liquid to be passed one way through it. Even when the valve is in open position valve lid is on the seat unless any liquid is pressurized from its inlet side.Any back flow will be restricted.

A screw-down non-return valve, also known as a check valve, prevents backflow in a piping system by allowing fluid to flow in only one direction, using a spring or gravity to close when flow reverses. In contrast, a globe valve is designed for controlling flow and pressure within a system; it features a spherical body and a movable disk that can be adjusted to open or close the flow. While the screw-down non-return valve focuses on preventing reverse flow, the globe valve is primarily used for regulating flow rates.

The PCV Valve is located in between the valve cover and the air cleaner. There is a vacuum hose that connects to the top of it. You will need to remove the air cleaner first and then remove the vacuum hose. Once the hose is removed you will need to remove 1 screw from the small bracket that is holding down the PCV Valve. Be careful and try not to messup the head of the screw, as the material that the screw is made up of is quite soft. So use a screw driver that fits the head.
you need to find the bleeding screw that is located on or by the thermostat housing.you'l know that is a bleeding screw/valve because the bolt is not holding anything down. you'll turn it with the car off. you will see a pin size hole on it. turn on your car and when coolant start to flow out of it you have succesfully taken out the air from the cooling system. answer the coolant system bleeder is generally on water pump the bleeder looks same as a brake bleeder and works in exactly same way
To fill air in a Presta valve, first unscrew the top cap and press down on the valve to release any remaining air. Then, use a pump with a Presta valve adapter to inflate the tire to the recommended pressure. Finally, screw the top cap back on to secure the valve.
To inflate a Presta valve, first unscrew the top cap and press down on the valve to release any air inside. Next, attach a pump with a Presta valve adapter to the valve stem. Pump air into the valve until you reach the desired pressure, then remove the pump and screw the top cap back on to secure the valve.
To pump up a Presta valve, first unscrew the top cap and press down on the valve to release any air inside. Then, attach a pump with a Presta valve adapter and pump air into the valve until it reaches the desired pressure. Finally, screw the top cap back on to secure the valve.
To use a Presta valve on a bicycle tire, first unscrew the small nut at the top of the valve. Press down on the valve to release any air inside. Attach a pump with a Presta valve adapter and inflate the tire to the recommended pressure. Finally, screw the nut back on to secure the valve.
To fill a bike tire with a presta valve, first unscrew the top nut on the valve. Press down on the valve to release any air inside. Attach the pump nozzle securely to the valve and inflate the tire to the recommended pressure. Once inflated, screw the top nut back on to secure the valve.
after gate valve, because when you want make maintenance for sump pump , you don't want all water in the pipe drop down sump pump - gate valve - non return valve
