What is brass bibcock

Brass bibcock is a type of brass valves and flow control device that mainly used outdoors, there are two kinds of design: 1. ball bibcock, there is a chromed brass ball inside, function and operation is similar to brass ball valve -- open and close by handle 1/4 turn; 2. stop bibcock, on the other hand, operated by opening and closing the stem.

Applications of brass bibcocks

Brass bibcocks are most applied for outdoor pipelines, therefore also called outdoor taps, garden taps. Some of them are used for washing machines and other sanitary applications where a hose connections are needed.

How to select brass bibcock

1. Confirm the functions of brass bibcocks

different functions and applications require different types of bibcocks, for example, ball bibcocks, stop bibcocks, garden taps, washing machine bibocks etc..

2. Confirm the working pressure of brass bibcocks

depending on pipeline pressure needs, the brass bibcocks are designed with valve wall thickness and port sizes, such as PN16 brass bibcocks, PN20 brass bibcocks , PN40 brass bibcocks

3. Confirm bore size of brass brass bibcocks

There are three different types of brass bibcocks :

1). Full bore brass bibcock offers no flow restriction, which means that when it is open, the liquid can flow freely through it. This is achieved by making the ball larger than the passage size, so that the hole can be the same size as the passage.

2). Standard bore brass bibcock does not have an oversized ball, and as a result, the hole is one size smaller than the passageway. This creates a small amount of flow restriction as the fluid passes through.

3). Reduced bore brass bibcock, on the other hand, has an smaller ball and an even smaller hole, which creates significant flow restriction as the fluid passes through it.

4. Confirm thread type of brass brass bibcocks

Thread types differ from markets and applications: BSP threads for Europe and NPT threads for North America, also other metric threads, which you must confirm before buying brass bibcocks.

5. Confirm material type of brass brass bibcocks

We currently work with HPb57-3 brass radiator valves for most customers in Europe and Asia, CW617N brass bibcocks for Europe, C377700 and lead free brass for North America.

7. Confirm surface treatment of brass brass bibcocks

Rough brass color, nickel-plating, and chrome-plating are most widely used surface treatments for brass bibcocks. Plating helps to protect the bibcocks from oxygen and look shining.

How to install brass bibcocks

1. Clean and remove any objects from the pipes (in particular bits of sealing and metal), which could obstruct and block.

3. Ensure that both connecting pipes either side of the valve (upstream and downstream) are aligned (if they are not the brass spring bibcocks may not work correctly).

3. Make sure that the two sections of the pipe (upstream and downstream) match, the brass bibcock will not absorb any gaps. Any distortions in the pipes may affect the tightness of the connection, the working of the valve and can even cause a rupture.

Chemical compositions we use for brass bibcocks

1. China/Global Market

HPb57-3, HPb58-3, HPb59-1, HPb59-3 are most common materials used for China brass bibcock, which are acceptable for most countries in the world, except for those customers have special requirements.

HPb57-3, also called China Normal brass, a variant of CW614N brass, is a local industry standard, with little Fe contents in composition, and lower costs than CW614N. It’s widely used as a standardized material in China and accepted by most global markets and customers.

HPb58-3, is a variant of CW617N brass and commonly used for brass bibcocks in China local market.

HPb59-1, has less Fe, Pb and higher price costs, it’s more used for high-quality products or market, such as brass fittings for USA market.

2. European Market

CW614N and CW617N brass materials are widely used for European brass bibcocks.

CW617N brass has better physical property to stand higher working pressure and temperature, more importantly the Pb percentage share is less than 2.5% and applicable for drinking water systems, good for environment and people’s health.

CW614N Brass is also popularly used because of similar compositions and lower costs, suitable for those applications without much environmental requirements.

3. USA Market

C46500 and C377700 are most widely used materials for USA brass bibcocks.

As a requirement of AB1953 regulations, all the brass 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 bibcocks, 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.

Surface treatments of brass bibcocks

Surface treatments provide good protection to brass bibcocks

Rough color is brass bibcock body sandblasted and without plating.

Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of brass bibcocks, increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance.

How we produce brass bibcocks

1. Brass raw materials are bought from local suppliers in forms of brass bars.

2. Brass bars are cut into smaller pieces with different sizes according to order requirements, heated with natural gas.

3. The heated brass bars are forged by forging machines, Out-comings are semi-finished rough brass bibcock bodies.

4. The rough brass bibcock bodies are trimmed and cut off unnecessary parts.

5. The rough brass bibcock bodies are washed with sanding machines, to clean the dirty and oils during production.

6. The rough brass bodies are machined by CNC machinery for threads and dimensions.

7. The machined brass bibcock bodies are nickel- or chrome-plated.

8. The brass valves are ready for delivery after final finished goods quality inspection.

How we pack brass bibcocks

Brass bibcock packing is very important for safe transport and brand appearance.

We pack brass bibcocks in small inner boxes, then put into outer cartons, finally load in wooden pallets.

It will protect the goods well and can avoid damages and wet.

We also pack as per customers' OEM designs.

How we test brass bibcocks

Our test laboratory equips with various devices for brass bibcock quality inspect and control, as well as new product development.

Equipment include material spectrometer analyzer, flow rate tester, torque tester, body resistance tester, endurance tester, high-low temperature tester.

These equipment enable us to analyze brass bibcock material compositions and type tests according to related standards, ensure our brass bibcocks are correctly designed and produced.
