Heavy Duty Brass Float Valve

Brass Float Valve N10174001 is full brass made valve that used for water tank or swimming pool, full bore design allows big flow rate, heavy duty construction and brass rod make the valve can stand for higher pressure and long product life durability. The floating balls are available in copper, plastic, stainless steel for different applications. The brass float valve is flexible and durable, with high precision control. It is not disturbed by water pressure and tightly close without water leakage.

The floating ball always floats on water, and when the water surface rises, the floating ball also goes up. As the ball rises, the connecting rod also rises. The connecting rod is connected with the brass valve at the other end. When it rises to a certain position, the connecting rod supports the piston pad to close the water source. When the water level drops, the floating ball also drops, and the connecting rod drives the piston pad to open.

Different functions and applications require different valves, for example,  water brass float valves, gas brass float valves, sanitary brass float valves,  PEX brass float valves, tail brass float valves.

Depending on pipeline pressure needs, the brass float valves are designed with valve wall thickness and port sizes. There are low pressure ball valves, middle pressure ball valves, high press ball valves, super-high pressure ball valves. PN16 brass float valves are mainly used for domestic and plumbing applications.

There are three different types of brass float valves:

1). Full bore brass float valve 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 float valve does not have an over-sized diameter, 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 float valve, on the other hand, has an smaller diameter and an even smaller hole, which creates significant flow restriction as the fluid passes through it.

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 float valves.

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

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

There are currently three optional types of floating balls: copper ball, plastic ball and stainless steel ball. The costs differ much, plastic one is most economical and more used for common use.

1. Before installing brass float valve, clean and remove any objects from the pipes (in particular bits of sealing and metal), which could obstruct and block the valve.

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

3. Make sure that the two sections of the pipe (upstream and downstream) match, the brass float valve 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.

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

Rough color is brass float valve body sandblasted and without plating.

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

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 float valve bodies.

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

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

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

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

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

We pack brass float valves 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.

Our test laboratory equips with various devices for brass float valve 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 float valve material compositions and type tests according to related standards, ensure our brass float valves are correctly designed and produced.
