A ball valve is very important part in pipelines. In daily work, we often see some abbreviations related to ball valves, such as “CWP”, “WOG”, etc. What do these words mean, Let us take you to learn about them in detail.
What is the meaning of CWP
In a ball valve, CWP means Cold Working Pressure, it indicates the maximum allowable working pressure of the valve at a medium temperature of -20 degrees Celsius to 38 degrees Celsius. This is the working pressure of the valve in a cold state, also known as the cold working pressure.
CWP refers to the maximum allowable working pressure that the valve can withstand within a specific medium temperature range. This parameter is crucial to ensure the safe operation of the valve under various working conditions.
What is meaning of WOG
In ball valves, WOG means Water, Oil, Gas, which is the abbreviation for water, oil and gas. This means that the ball valve is suitable for these three different types of media.
In addition, the “1000″ in the 1000WOG ball valve indicates that its nominal pressure is 1000PSI, which is approximately equal to 68.94 kg or 6.894Mpa. Therefore, a 1000WOG ball valve refers to a valve with a nominal pressure of 1000PSI, suitable for water, oil and gas media.
Other Important Parameters of Ball Valves
In addition to CWP and WOG, ball valves have other important performance parameters, including:
Strength performance:
The ability of the valve to withstand the pressure of the medium must have sufficient strength and rigidity to ensure long-term use without cracking or deformation.
Sealing performance:
The ability of each sealing part of the valve to prevent the leakage of the medium is one of the most important technical performance indicators of the valve.
Flowing medium:
The medium will cause pressure loss after flowing through the valve, and this loss should be reduced as much as possible during design and manufacturing.
Opening and closing force and opening and closing torque:
The force or torque required to open or close the valve should be reduced as much as possible during design and manufacturing.
Opening and closing speed:
The time required for the valve to complete an opening or closing action. There are special requirements for the opening and closing speed under certain working conditions.
Action sensitivity and reliability:
The sensitivity of the valve to changes in medium parameters, which is particularly important for valves that adjust medium parameters.
Service life:
The durability of the valve, usually expressed by the number of opening and closing times or the use time to ensure the sealing requirements
