4 Tips for Selecting Different Types of Water Valves and Their Functions.
Water valves are essential components in any plumbing system. They regulate and control the flow of water from one area to another. There are various types of water valves with diverse functions, and choosing the right one for your needs can be challenging. Here are four tips to help you select the appropriate water valve for your plumbing system:
1. Know the function of the valve you need.
Before selecting a water valve, you must understand its function. Water valves serve distinct purposes, and choosing the wrong one can lead to complications in your plumbing system. Some of the common types of water valves include ball valves, gate valves, globe valves, and check valves. .
- Ball valves are used to control the flow of water to appliances like sinks, toilets, and showers. They have a lever that turns a ball-shaped valve within the housing to open or close the water flow.
- Gate valves are used to control larger water systems like in commercial settings. They're either opened or closed fully and not intended to regulate flow volume.
- Globe valves are used to control water pressure. They are mostly used in irrigation systems.
- Check valves prevent the backflow of water to prevent water wastage or contamination. You need to identify the specific function you need to pick the right valve.
2. Consider the material of the valve.
The material of the valve is an important consideration when choosing a water valve. Different materials provide varying durability, resistance to corrosion, and other factors. The most common materials used in water valves are brass, copper, plastic, and stainless steel.
- Brass valves are durable and resistant to corrosion, making them ideal for most plumbing applications.
- Copper valves are thermally and electrically conductive, great for heating or cooling applications.
- Plastic valves are lightweight, easy to install and maintain, and ideal for residential use.
- Stainless steel valves are resistant to corrosion and high temperatures, commonly used in industrial settings.
3. Take note of the valve's size and connection type.
The size of your valve must match the size of your pipe and fitting. Likewise, the connection type will depend on the surrounding plumbing fixtures. Some of the common connection types include threaded connections, compression fittings, and soldered connections. Ensure you have the correct sizing and connector type before making a purchase.
4. Choose a valve with the appropriate pressure rating.
Another crucial factor to consider when selecting a water valve is the pressure rating. Water valves have different pressure ratings depending on the location and application. Valves with high-pressure ratings are better fitted for larger commercial systems, while low-pressure valves are ideal for domestic use.
- Low-pressure valves have a pressure rating between 300-400 psi.
- Medium-pressure valves have a pressure rating between 400-600psi.
- High-pressure valves have a pressure rating above 600psi.
Conclusion.
Selecting the appropriate water valves is an essential aspect of any plumbing project. Understanding the valve's function, material, size, connection type, and pressure rating is crucial when obtaining the right valve for your system. Make sure you consult with plumbing professionals or suppliers before making a final purchase to ensure the valve meets your system's specific requirements.
