How well the control valve can be used stably over a long period of time is dependent on the selection method. Fluids flowing inside the valve can have various characteristics and conditions, and various standards can apply.
To ensure that all these conditions are taken into consideration so as to select the most suitable valve, we have provided resource materials. Please make effective use of these.
Standard Body Format Selection Guide
We here introduce a list of valve formats and utilizations, as well as jacket specifications and other optional specifications.
Please use these for reference when selecting a valve that meets the usage objectives.
Main Drive Formats and Body Combinations
We here introduce a list of drive (actuator) formats, and body combinations.
Please use these for reference when checking the valve format specifications.
A bonnet is selected to match the fluid temperature or the properties of the fluid that flows inside the valve.
In particular, please consider use of the bellows-type bonnet, which can completely stop any leaks from the ground packing part, because of its performance record in a majority of deliveries.
Valve Plug Characteristics/Shapes
The fluid volume characteristics or valve plug characteristics, etc., are explained in the valve’s basic performance.
Suitable selection among various valve formats to match the utilization is a necessity.
Cavitation and Flashing
Cavitation and flashing need to be taken into consideration, because they can have an effect on valve life.
As the conditions, etc., for occurrence of cavitation are clearly laid out, please refer to them.
Valve Body Materials
Selection of optimal materials in consideration for corrosion resistance and durability, and in accordance with regulations and other standards, is necessary.
Please use these for reference when selecting materials.
Since this is a part that directly controls the fluids, a high durability is demanded.
Make a decision from fluid conditions, select the optimum materials and hardness, and maintain durability.
Please use these as references when checking the hardness requirement.
