They are usually mounted externally and are found on radiators, water heaters, and fuel pumps. A hand valve is made up of a flexible rubber diaphragm surrounded by a layer of steel mesh or other similar material. The top of the diaphragm has a ball or wick, which when turned allows a regulated amount of gas flow through the rubber diaphragm. Note: Hand valve should be placed either fully opened or fully closed.<br><br><br>Turning the hand valve clockwise about 1 turn will open the valve. Turning the valve about nine more turns will fully close the main valve. If you are replacing a hand valve, first check for leaks around the ball or wick, and then replace it. If your valve does not have a leak, but there is air pressure in the flapper valve, you can clean it with a blower or use an air compressor to force out the air pressure in the flapper valve, and then clean the ball or wick if you are using a heater or blower to maintain the proper pressure. Insulate the hose used to control the flow of gas from the burner or furnace.<br><br><br>If you have a hand valve and your blower is not working properly or causing too much friction, you should check the brake line to see if there is any corrosion. If you discover rust on the control valve, you may have to replace the entire assembly. If you have a hand-held trailer, make sure you check the brake lines as well to avoid excessive wear.<br><br><br>As stated above, a hand valve can open or close automatically based on the amount of air pressure in the tank. The way this works is that there is a hole in the bottom of the hand valve has two wires inside that release either positive or negative pressure. When there is no air pressure in the tank, the valve will stay closed and continue to work. When there is a substantial amount of air pressure in the tank (more than 15 PSI), the hand valve will open and allow the vehicle to move independently of the wheels. The best way to check for the proper amount of air pressure in the system is to use a measuring tape to determine the distance between the top of the tire and the edge of the tire.<br><br><br>Hand valves can be manually used in hot or cold steam conditions. Occasionally, these valves will be used without the assistance of a motor. This is most commonly seen in applications where the steam is used to assist in driving a vehicle. These hand valves are sometimes used instead of valves that use electricity to function.<br><br><br>Another type of hand valve is the pressure relief hand valve. These are used in some braking systems to allow for controlled air pressure. Typically, there are three different speeds: slow, medium, and fast. This allows for the user to be able to adjust the braking system for any specific situation and the exact amount of pressure needed.<br><br><br>One of the more common uses for a hand valve comes in the form of a parking brake. In most parking situations, it is impossible to anticipate where the car will be in relation to the center of gravity. This means that there are times when a parking brake is needed to hold the car in one place while waiting for other vehicles to stop at a red light. Typically, this will be implemented with automatic transmission parking brakes.<br><br><br>Hand valves can also be used for air-pressure control on trailer brakes.

These devices are utilized during the release phase of the emergency system to allow for the increase or decrease of pressure. They are sometimes used as a mode hand valve on motorcycle trailers. The purpose of a hand valve is to prevent the loss of pressure while a high pressure warning is displayed to warn of excessive loss of air pressure.<br>
