It is the wisdom and experience of the Chinese that has made the China valve a much sought after product across various industries. Valves from china are trusted for their reliability. Thousands of years ago when it was realized that some sort of safety precautions or devices will be needed in order to protect human beings who use any pressurized system, the Chinese had already invented a cauldron that had hinged lids for a controlled production of steam.
You can use a China valve at any place or in any machine where the MAWP or the maximum allowable working pressure is exceeded. Safety valves were originally designed to prevent physical injury to people handling the pressurized systems but now it is increasingly being used in factories to even protect the products being manufactured against excessive pressure. This ensures the safety and security of the employees working in the factory and other work places where security is most required.
There are different definitions based on the United States, European Economic Area standards, German, Japanese and Korean standards. In any safety valve including a China valve, the basic design consists of the valve body that has a tight angular pattern with a nozzle or an inlet that is placed on top of the pressurized system. The nozzle or connection for outlet is usually screwed or flanged to a piped discharge. There are some systems where there is no outlet connection; instead the fluid is let out into the atmosphere directly. The safety valve is simple and self acting device which provides protection across various industries.
The main decision in purchasing safety valve for any industry is based on certain common factors and some that are unique to a particular industry. The common factors for selecting any safety valve whether you are purchasing a China valve or any other is;
*Cost: this will again be dependent upon the size and the capacity of the valve.
*The type of disposal system: you must be very certain of the usage of the valve when you ponder on this factor. The systems for steam, non toxic gas, air etc. can easily go for valves that have an open bonnet. Others should use those valves that have a closed bonnet. Then there is the consideration for systems that have superimposed back pressure; for such balancing elbows will work better.
Safety Valves have been in use ever since mankind discovered the power of steam. In fact the Chinese have been known to use valve like devices as far back as 2000 years ago.
