What is compression brass strainer valve

Brass strainer valve is an indispensable device on the pipeline of the conveying medium. It is usually installed at the inlet of a pressure reducing valve, a pressure relief valve, a fixed water level valve or other equipment to eliminate impurities in the flow to protect the valve and equipment normal use. When the fluid enters the mesh filter with a certain specification filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter screen and reload it after treatment, therefore, it is extremely convenient to use and maintain.

Applications of compression brass strainer valve

Compression brass strainer valve is used for the coarse filtering of liquid pipeline and the filtration of large particles of gas or other media. It can remove the larger solid impurities in the fluid, so that the machinery and equipment (including compressors, pumps, etc.) and instruments can work normally and operation, to achieve a stable process and ensure safe production.

How to select compression brass strainer valve

1. Confirm the functions of compression brass strainer valve

different functions and applications require different filter valves, for example, water brass filter valves, gas gate valves, sanitary compression brass strainer valves, flange compression brass strainer valves, PEX compression brass strainer valves, tail compression brass strainer valves.

2. Confirm the working pressure of compression brass strainer valve

depending on pipeline pressure needs, the compression brass strainer valves are designed with valve wall thickness and port sizes. We have low pressure compression brass strainer valves, middle pressure compression brass strainer valves, high press compression brass strainer valves, super-high pressure compression brass strainer valve. Low and middle pressure compression brass strainer valves are mainly used for domestic and plumbing applications.

3. Confirm bore size of compression brass strainer valve

There are three different types of compression brass strainer valve:

1). Full bore compression brass strainer valves 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 compression brass strainer valves 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 compression brass strainer valves, 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 compression brass strainer valve

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 compression brass strainer valve.

5. Confirm material type of compression brass strainer valve

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

7. Confirm surface treatment of compression brass strainer valve

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

How to install compression brass strainer valve

1. Before installing compression brass strainer valve, make sure the pipe flow direction confirmed to valve installation direction, which can be found on compression brass strainer valve body.

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

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

4. Make sure that the two sections of the pipe (upstream and downstream) match, the compression brass strainer 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.

Chemical compositions we use for compression brass strainer valve

1. China/Global Market

HPb57-3, HPb58-3, HPb59-1, HPb59-3 are most common materials used for compression brass strainer valves China, 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 compression brass strainer valves 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 compression brass strainer valves.

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 compression brass strainer valves.

As a requirement of AB1953 regulations, all the compression brass strainer 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.

Surface treatments of compression brass strainer valve

Surface treatments provide good protection to compression brass strainer valves:

Rough color is compression brass strainer valve body sandblasted and without plating.

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

How we produce compression brass strainer valve

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 compression brass strainer valve bodies.

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

5. The rough compression brass strainer valve 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 compression brass strainer valve bodies are nickel- or chrome-plated.

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

How we pack compression brass strainer valve

Compression brass strainer valve packing is very important for safe transport and brand appearance.

We pack compression brass strainer 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.

We also pack as per customers' OEM designs.

How we test compression brass strainer valve

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