Pressure medium is diverse, such as water and air, as well as those with properties such as corrosive, flammable and toxic. If a pressure gauge is not applicable to these media, the gauge can not meet performance and even has a potential danger when used. Wet part materials can be hence selectable and special treatment to the part is accommodable.
|Category in use||Special Treatment||Indication||Applicable Pressure Medium|
|Wet part material|
|General||Cu-alloy||―||―||Non-corrosive liquids, gasses, water, oil and air, etc.|
|Vapor and 45 to 80C non-corrosive fluids or gasses|
(Cooling fin needed over 80C and discussion to determine specifications for remote diagram type required.)
|Fluid without elusion of Zinc or lead from the material (brass/solder) used Foods, Medical care, Pure water|
|Liquids or gasses not to impede property of stainless as corrosion resistance, chemical resistance, heat resistance and durability Chemical- and Food-related|
Others (Discussion needed)
|―||(Discussion needed to fix a material)||(1)
Corrosive fluid, medium possessing characteristics of high viscosity or potential risk of solidification inside Chemical- and Food-related
|Degreasing||USE NO OIL||Liquids or gasses not to contain oil Oxygen, Foods, Medical device|
|Cleaning-up||USE NO OIL,
|Liquids or gasses that require internal cleaning-up to avoid leakage of substance excluding clean air from wet part Foods, Pure water, Medical care, Semiconductor-related|
|Gas leakage test||Gas name,
|Liquids or gasses not to permit even less leakage and those with properties such as toxic and flammable
Gasses such as ammonia, (2) acetylene, propane and Freon
(1) Corrosive fluid: There is no material that can withstand all corrosive fluids. So, please let us know the name of fluid so that you can select the most suitable material.
(2) Acetylene gas: Usage of silver or copper alloy with copper content of 75% or more should be prohibited for wet part material. Thus, please be sure to contact us so that we can provide any appropriate solutions, accordingly.
