Compression Angle Stop Valve

Compression brass angle valve N10121003 is classical design for sanitary applications, PN16 rated, with compression outlet which can quick connect to hose and pipes. the angle valve body is hot forged with fine brass material, polished and chrome-plated valve body, strong enough to high pressure water line. Every single of the compression brass angle valve is leakage tested during production.

Compression brass angle valve is called "angle valve" because its water inlet and outlet are perpendicular to each other at a 90-degree angle, instead of straight in and out like a ball valve. The main function of the compression brass angle valve is to switch the flow and control the flow pressure: 1. connect outlet flow to inlet, 2. adjust the flow pressure by turning the angle valve,  3. Turn off the flow in case of the faucet leaks, 4. Good appearance.

Considering the service life, it is best to choose stainless steel or all-copper compression brass angle valve, which can generally be used for more than 10 years; pay attention to distinguish the material of the brass angle valve, generally look in from the water inlet along the light, and there are small white spots on the wall. Zinc alloy, which is yellowish but rough, is made of iron, and yellow or yellowish-white and smooth is copper.

The valve core is the heart of the compression brass angle valve. It is closed firmly and the life span depends on it, especially the sealing ring and ceramic disc inside. Generally good brass angle valves use ceramic cartridges. You can try the feel. If the feel is too light, it will leak after a short period of time. If the feel is too heavy, it is inconvenient to switch.

When buy compression brass angle valve, you must carefully check the workmanship details of the compression brass angle valve, such as whether the electroplating luster of the brass angle valve is smooth and shiny, whether the appearance is blistered or scratched, and the hand is smooth and flawless.

1. Choose an compression brass angle valve with the same specifications as the inner wire interface. If the inner wire connection is 4 points, then the selected compression brass angle valve must also have a 4 point interface.

2. Use the raw material tape to wrap the screw port of the compression brass angle valve. Pay attention when winding it. The winding direction of the raw material tape should be opposite to the thread direction of the compression brass angle valve. If the thread direction is installed in a clockwise direction, the raw tape should be wound in a counterclockwise direction.

3. The thread of the compression brass angle valve is installed in a clockwise direction, so the raw material tape is wound in a counterclockwise direction, and it can be cut by winding about 5-10 times.

4. Insert the compression brass angle valve wrapped with the raw material tape into the inner wire interface, and turn it clockwise until it is tightened. It can be screwed to the end of the compression brass angle valve thread. If the strength is not enough, you can use a wrench to bite the corners of the compression brass angle valve and continue to screw it to the end.

5. Turn on the switch to test whether the compression brass angle valve is leaking. If there is water leaking at the interface, you can remove it, wrap the raw material tape and repeat the above operation.

 USA compression brass angle valves generally use C46500 and C377700 brass.

As a requirement of AB1953 regulations, all the compression brass angle valve parts which contact the water shall have Pb content less than 0.25%, also called lead-free brass or no-lead brass, all the brass water valves for USA market, such as ball valves, brass gate valves, brass check valves, brass angle valves, have been compulsory to use lead free brass.

For those brass valves not for water use, such as brass radiator valves, heating valves, C377700, or China standard HPb59-1 brass materials are workable.

Compression brass angle valve is polished and chrome-plated. The chromium plating has high hardness, the surface finish of the processed compression brass angle valve is very good, not only will not rust, but also can be better anti-corrosion. If the size of the angle valve does not meet the requirements, chromium can be added to achieve the size. It should be said that the appearance of the chrome-plated compression brass angle valve is relatively smooth and beautiful.

Customer designs are also acceptable, such as single small box for each compression brass angle valves, print customer logo.
