What is Valve definition?

valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways

What is a valve body?

The valve‘s body is the outer casing of most or all of the valvethat contains the internal parts or trim. The bonnet is the part of the encasing through which the stem (see below) passes and that forms a guide and seal for the stem.

The types/classification of valves

1.Ball Valve

Ball valve is a quarter turn operated valve. The closure member is a spherical plug with a through hole. When the valve is in open state, the through hole is in-line with the fluid flow and hence, the fluid passes through it.

2.Gate Valve

Gate valve is a sliding type of valve. In gate valves, the closing member is a metal gate.

3.Plug Valve

Similar to ball valves, plug valves are also quarter turn type of valves. This valve consists of a plug which can be either cylindrical or conical in shape.

4.Butterfly Valve

Butterfly valves are most simple yet versatile valves. They are quarter turn operated valves which are commonly used in multiple industries for varied applications.

5.Globe Valve

Globe valve is a linear motion type of valves and is typically used in both on-off and throttling applications.

6.Pinch Valve

Pinch valves consist of a plastic tube/sleeve which is made up of reinforced elastomers. The sealing/ closing action is achieved by throttling or pinching this sleeve/tube.

7.Disc Check Valves

Disc check valves, also called as non-return valves allow the flow to pass through them in only one direction and stop the flow in reverse direction.

The Components of Valve:

1.Body

The valve’s body is the outer casing of most or all of the valve that contains the internal parts or trim.

2.Bonnet

A bonnet acts as a cover on the valve body.

3.Ports

Ports are passages that allow fluid to pass through the valve.

4.Handle or actuator

A handle is used to manually control a valve from outside the valve body.

5.Disc

A disc or valve member is a movable obstruction inside the stationary body that adjustably restricts flow through the valve.

6.Seat

The seat is the interior surface of the body which contacts the disc to form a leak-tight seal.

7.Stem

The stem transmits motion from the handle or controlling device to the disc. The stem typically passes through the bonnet when present. In some cases, the stem and the disc can be combined in one piece, or the stem and the handle are combined in one piece.

How is quality controlled in China Sourcing ?

What is quality control?

Quality control, or QC for short, is a process by which entities review the quality of all factors involved in production.

Notable approaches to quality control

1.Statistical quality control (SQC):

The application of statistical methods (specifically control charts and acceptance sampling) to quality control.

2.Statistical process control (SPC):

The use of control charts to monitor an individual industrial process and feed back performance to the operators responsible for that process. Inspired by control systems.
3.Six Sigma (6σ):

Statistical quality control applied to business strategy. Originated by Motorola.

What is the difference between quality control and quality assurance?

The difference is that QA is process oriented and QC is product oriented. Testing, therefore is product oriented and thus is in the QC domain. Testing for quality isn’t assuring quality, it’s controlling it. Quality Assurance makes sure you are doing the right things, the right way.

What are the quality control tools?

There are 7 Quality Control tools namely Check Sheets, Cause and Effect Diagram, Histogam, Pareto Diagram, Scatter Diagram, Control Chart, Flow Charts.

How important is quality control?

It entirely depends on how much importance you are giving to your customers, in the long run only quality will payoff, so if organisations are looking for short term profits then they would consider quality as a cost rather than as an investment in future of the organisation.

Why use a China sourcing firm?

You’ve probably heard that China sourcing can save your company money. This is certainly true, but it’s not the only benefit to China sourcing.

Why use a China sourcing firm?

There are many excellent factories in China;however, dealing with Chinese factories requires a lot of experience in terms of effective communications (in Chinese), product quality control process (material requirement, processing technologies, mid-production and end product quality testing), shipping and export management. Using a professional company like CSMFG will help you buy goods from China with much less hassle and even lower cost!

The reason why use a China sourcing firm:

1.Saving on Labor and Overhead

Sourcing companies have dedicated facilities, and have determined the most cost-effective ways to manufacture products. Because of this, they have the capacity to produce quickly and at a lower a cost.

Outsourcing your manufacturing needs to experts improves efficiency. Simply put, there’s no need for your company to reinvent the wheel–or to manufacture it.

2.Using Nearby Resources

Rental costs tend to be cheaper overseas as well. The taxes for manufacturing your product abroad will also be much lower.

Of course, you want to be careful not to outsource to manufacturers who mistreat their workers. This is why it’s important to go through a sourcing company, who will handle that logistical work for you. But we’ll talk about that later in the article.

3.Focusing on What’s Important

Raw materials aren’t the only resource that can be easier to find abroad. In some cases, other countries have more workers with the particular skills you might need to manufacture your product.

4.Focusing on What’s Important

This is one of the ways outsourcing actually helps improve the US economy and create American jobs. It’s important to note that these jobs also tend to be higher-paying than manufacturing jobs.

12 Tips help you looking for suppliers from China

1.Be aware that while the decision-maker may not speak any English, establishing good relationship (guanxi) with the top management is crucial for long-term success.

2.Email is good for exchanging product specifications, catalogue and price list. To establish a deeper relationship, a phone call is 10 times better than email. A personal meeting is 100 times better than a phone call.

3.Just because a site is ranked higher in Google search listing, this does not necessarily mean it is a more serious business.

4.An independent third party can be an excellent idea for a quick cost effective review of potential suppliers before you choose one to visit.

5.Information comes from seemingly insignificant data, for example, the email addresses may reveal useful information about Chinese suppliers.

6.Suppose you come up with a product idea or think you have market channels for certain products, and you want to find a supplier in China because of the low product development cost and low production cost there.

7.This is the best way to verify your suppliers – you can’t know much about an organization unless you visit it. You can also discuss your products, prices, quality inspection, and delivery time face to face.

8.You should talk to other companies within or outside of your industry, which are already doing business in China. You could first focus on your competitors. Search information relating to your product or service.

9.If you find the above overwhelming or you don’t have time to start examining different supplier options, you could consider hiring a sourcing agent. This will naturally cost more, but it can help you to find a suitable supplier more quickly.

10.Another great source for finding suppliers and additional information are your country’s trade organizations and business chambers. These organizations can provide you contact details and establish first contacts in the country.

11.Unsurprisingly, the Internet is the perfect place to begin your search. You should use it to conduct preliminary research and get an overview of what kind of supplier options are available.

12.The key is to remember there are a number of B2B websites and business directories out there, but not all of them are legitimate. Deal only with trustworthy and credited websites. In addition, you should ensure the suppliers are verified.
