The purpose of background verification for contract employees is to provide useful information about personal history, assess whether they may pose a threat to others or whether they are trustworthy. It aims to help build more trust relationships and security in society and the workplace.

The general background investigation is mainly carried out from two aspects of educational background and work experience. Business owners usually sign contracts with pre employment background screening companies specializing in employment records background check, background investigations employment , which may include criminal records, employment records, credit records, driving records, and even medical records. However, it is estimated that more than 40% of resumes may contain false or modified information, and false information about new employees is risky for business owners. Big data shows that fraud, corruption, kickbacks, theft, disclosure of company secrets and commercial espionage are often carried out by internal employees

RedStar's is the companies that do employee surveys, employment background check agencies , which conducting background checks on current employees services assist companies to conduct in-depth background checks on candidates for core positions in the company, to fully understand and confirm employees' past work experience, especially work experience, education, work conditions, professional ethics, performance status, colleagues or the company Evaluation, etc. By an in-depth understanding of the capabilities and integrity of the interviewees, the company's capital, technology and personnel risks can be effectively reduced.

Engineering Construction Industry

The engineering construction industry has many difficulties, unbalanced market supply and demand, vicious competition, the actual price is won, the construction project has a large investment, the construction period is long, the construction is difficult, the technology is complicated, the project participants are numerous, and the receivables are difficult to recover.

Financial Investment Industry

Based on the high-risk feature of the industry, the financial investment industry faces a variety of fraud risks, including bankruptcy fraud, attracting fraud, contract fraud, bill of exchange fraud, cheque fraud, collateral fraud, mortgage fraud, misappropriation of public funds, etc.

IT And E-commerce

The e-commerce transaction model has more risks than other business models. The root cause of the risks lies in the people who bring these risks, especially the core personnel working in the enterprise (such as programmers, salespeople, and managers).                            

Manufacturing

Manufacturing is facing a turning point in growth and opportunity in a complex global competitive landscape. Companies must constantly respond to unprecedented risks, pressures, and uncertainties to maintain competitive advantage and achieve faster speeds and scale than their competitors.    

Real Estate Industry

The risks of the real estate industry are not only likely to cause serious problems in the social, policy, economic and other fields, but also the human and project risks, including the core personnel leaking important resources of the company, the default and management of the property company, and the abuse of power by the owners.            

Wholesale and Retail Trade  

Wholesale and retail industries include Internet retailing, franchise retailing, the risks of facing commercial theft, business fraud, employee corruption, and disruption of suppliers and distributor channels, which may result in reduced revenue, reduced market share, increased costs, and damage to the reputation and customer confidence of the business.

How to hire a Chinese PI (Chinese private investigator)

Investing in China, starting or developing a company in China, or doing business and business with Chinese companies are difficult tasks. You don't know if that person is as real and legal as they say. Who should you trust?

There are hundreds of reasons to hire private corporate detectives, background credit investigations, collecting business intelligence, investigating insurance claims, finding missing persons, personal administrative protection, and more. Sometimes, you can't just rely on a $ 9.99 Internet database search to get the information you need. You need to hire the right people and make the right decisions.

Balance valve is a dynamic and static balancing valve under hydraulic conditions. Such as static balance valve, dynamic balance valve.
Valve body material: cast iron, cast steel,
Work pressure is 0.6-4.0 MPA.
The working temperature is - 5 C - 350 C.
Valve caliber DN15-DN300,
Connection mode: flange, internal thread,
Driving mode: manual and electric.
Manufacturing standard: national standard.

How do balancing valves work?
Balancing valve is a special function valve. It has good flow characteristics. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal. As long as the balance valve with appropriate specifications is installed in each branch and user's entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value.
Static balancing valves are also called balancing valves, manual balancing valves, digital locking balancing valves, double-position regulating valves, etc. It is through changing the clearance between the spool and the seat (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating flow. Its object of action is the resistance of the system, which can distribute the new water in proportion to the design calculation, increase and decrease the branches in proportion at the same time, still meet the flow demand of part of the load under the current climate needs, and play the role of heat balance. Dynamic balancing valves are divided into dynamic flow balancing valves, dynamic differential pressure balancing valves, self-operated differential pressure control valves and so on.
Dynamic flow balance valve is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. It automatically changes the drag coefficient according to the change of system working condition (differential pressure). In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. On the contrary, when the pressure difference decreases, the valve opens automatically and the flow rate remains constant. However, when the pressure difference is smaller or larger than the normal working range of the valve, it can not provide additional pressure head after all. At this time, the flow rate of the valve to the full open or closed position is still lower or higher than the set flow rate can not be controlled.
Dynamic differential pressure balancing valve, also known as self-operated differential pressure control valve China, differential pressure controller, constant voltage variable synchronizer, differential pressure balancing valve, etc. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. The differential pressure control valve working principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system, that is, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases by automatically closing the valve. When the pressure difference decreases, the valve opens automatically, and the pressure difference remains constant. The self-operated pressure difference control valve has an automatic plug closing state within the control range. The pressure difference between the two ends of the valve exceeds the preset value. The plug opens automatically and adjusts the opening automatically under the action of the pressure sensitive film to keep the pressure difference between the two ends of the valve relatively constant.
