As the valve handle turns, the ball also turns, reducing the size of the opening. This decreases the flow rate and can lead to a perceived decrease in water pressure. It affects outlets like faucets or showerheads. However, a ball valve doesn't actually reduce the system's inherent pressure; it only restricts the flow.
It can be used to control flow by its main characteristic, the ball, being open or closed.
If necessary, ball valves can be used for throttling in: Systems that don't require precise adjustability or control. Low-pressure applications. Systems with inexpensive or expendable media.
Adjust the Valve: Turn the valve slowly to reduce the flow of water into your home. Turning it clockwise typically decreases the flow and pressure. Check Pressure: After making adjustments, check the water pressure using a pressure gauge.
flow control
ball valves: ideal for on/off control but not suitable for throttling as it can cause damage to the valve. gate valves: better for applications where minimal flow resistance is crucial but not ideal for precise flow control.

Limited Flow Control:
Ball valves have a relatively limited flow control capability. The design of the valve with a full bore ball can lead to a higher pressure drop, especially in larger sizes. This can restrict the flow and result in a reduction in efficiency.
If you're dealing with ongoing high water pressure, you should check on your regulator. You may be able to lower your water pressure by adjusting the regulator, or you might need to replace it with a new one.
High pressure
You can turn your internal stop tap (usually under your kitchen sink) down slightly to reduce the flow. You can also install a pressure reducing valve on your private pipework, which allows water to flow into it and reduces the pressure to a required setting.
Reducing water pressure by partially closing a valve is not recommended as it can cause damage to the valve and the plumbing system. Instead, adjusting the water pressure should be done using a pressure reducing valve, which is specifically designed to manage the pressure safely and efficiently.
The short-throw actuation of a ball valve makes it an ideal option for flow control where full open or closed states are common or where fast state switching is required. The design also allows for an exceptional air-tight seal.
Globe valves are the most commonly used type of flow control valve. They regulate the flow of liquid by controlling the distance between a plug and seat in the valve body. The plug gradually moves closer to or away from the seat depending on how much pressure is applied to the valve.
Ball valves are quarter-turn valves used in residential, commercial, and institutional applications to control the on-off flow of liquids and gases. They are available in a range of sizes, materials, and connection types.
Gate valves are not suitable for throttling volume. The control of flow is difficult because of the valve's design and the flow of fluid slapping against a partially open gate can cause extensive damage to the valve. Except as specifically authorized by the manufacturer, gate valves should not be used for throttling.
While a ball valve can operate in a partially open position, it is generally recommended to use it fully open or fully closed for optimal performance and longevity, unless it is a specialized ball valve designed for throttling. For precise flow regulation, other types of valves may be more appropriate.
If you tighten the screw the water pressure will be more and if you loosen the screw the water pressure will be less. Turn the screw clockwise to tighten it and increase the pressure, or turn it counterclockwise to decrease the pressure. Do not be too hasty.
Most residential plumbing systems are designed to handle 40 to 60 PSI of pressure, with 80 PSI being the typical maximum and anything over 100 PSI being possibly detrimental to plumbing components.
It's important to maintain your home's water pressure within an acceptable range. The ideal water pressure ranges between 40 and 80 pounds per square inch, with the recommended home water pressure at 60 psi.
The ideal water pressure level is between 50-70 PSI.
If your water pressure goes above 70 PSI (even occasionally), you should install a pressure regulator to your main water line.
If you have high water pressure, try regulating that pressure by closing your stop tap ever so slightly. How to find & operate your stop tap.
The ideal well water pressure is between 40-60 psi. If you're uncertain whether your water pressure falls within this range, learn how to test your water pressure. It's a good skill to learn. Checking your water pressure a few times a year can help you detect problems before they get worse.
When using a valve for low-pressure applications, it is preferable to utilise a low-pressure valve. A high-pressure ball valve is designed to withstand more significant working pressures while allowing a continuous fluid stream to flow through the valve.
Ball valves are recommended for applications that require frequent, quick control over the flow of liquid. Water hammer: Because ball valves can open and close immediately, they are more likely than gate valves to cause water hammer.
PVC ball valves are durable and can withstand high temperatures and pressures. They are also corrosion resistant and have a long lifespan and are considered as oil and gas valves because they are typically used in industrial applications but can also be used in residential applications.
