How to choose an angle valve? Beware that the ... - simpleprojectus

Angle valves are a very important part of the home plumbing system and are often installed at the connection between the water pipe and the toilet. Choosing the right angle valve not only helps to improve the efficiency and safety of the plumbing system, but also effectively avoids problems such as plumbing leaks.

The factors to be considered when choosing angle valve
1. Material
Angle valve material is one of the key factors affecting its performance and durability. Common angle valve materials are as follows:

Stainless Steel: Stainless steel angle valves are usually the most durable option, resistant to corrosion and suitable for use in all types of plumbing systems in the home. It is not prone to rust or damage and has a long service life.

Copper: Copper angle valves are also a good option for home use as it has good corrosion and oxidation resistance. Copper angle valves are usually slightly more expensive than stainless steel angle valves, but they are also very stable and long lasting.

Plastic: Plastic angle valves are generally lighter and less expensive, but have relatively poor durability and are suitable for low budget projects or non-long term use.

2. Size
The size of the angle valve should match the size of the home plumbing. Common angle valve sizes include 1/2-inch and 3/4-inch, but when choosing one, it's important to make sure it matches your home's existing plumbing connections. Improper sizing can lead to difficult installation and possibly even leaks.

3. Valve sealing performance
Sealing performance is a key point of concern when choosing angle valves. High-quality angle valves usually use wear-resistant, high-pressure resistant seals to ensure that there is no leakage when the water flow is closed. Leakage will not only waste water, but also may lead to corrosion of water pipes and even damage to home equipment.

4. Avoid common mistakes
Neglecting quality: Cheap angle valves may work fine for a short period of time, but over time, problems such as water leakage and corrosion may occur. Choose high-quality products to avoid excessive cost savings.

Do not consider the installation space: when installing angle valves, make sure there is enough space to operate the valve to avoid angle valves being installed too compactly, affecting normal use.

Neglecting maintenance: Maintenance of angle valves is often neglected. Regularly check and keep the valve in good working condition to avoid potential water loss.

With the above guide, you should be able to find the right angle valve on the market for your home to avoid problems such as leaks. Remember, choose the right angle valve to keep your home safe and comfortable with your plumbing system!

Frequently Asked Questions (FAQ)

Q1. Can I use an angle seat valve for steam?

Yes! They are actually one of the best choices for steam. Just make sure the valve has PTFE seals to handle the high heat.

Q2. What is "Water Hammer" and why should I care?

It’s a pressure surge that happens when a valve closes too fast. It sounds like someone is hitting your pipes with a hammer. It can break joints and sensors. Choosing a "Flow Below Seat" valve prevents this.

Q3. Do I need a plastic or stainless steel actuator?

If the valve is going to be sprayed with water or chemicals (like in a food plant), go with stainless steel. For a dry, indoor factory setting, plastic is usually fine and saves you money.

Q4. What air pressure do I need to run the valve?

Most pneumatic actuators require between 4 to 8 bar (roughly 60 to 115 psi) of air pressure to operate reliably.

5. Can I install the valve in any position?

Generally, yes. Angle seat valves can be mounted vertically or horizontally. However, mounting them with the actuator upright is usually best to prevent sediment from settling in the actuator seal.
