【Q4】How should I select the combination of the body and the diaphragm?

  1. Check the operating conditions (fluid type, concentration, temperature, etc.).
  2. Select the body type according to the fluid type.
    Wear type diaphragm valve (400 type): For corrosion resistance, airtightness or flow rate control requirements.
    Straight diaphragm valve (500 type) : For abrasive fluids (such as powder and solid).
  3. Select the material of the body and diaphragm according to the "Material selection table". Select materials suitable for use based on the operating conditions such as the type, temperature, and concentration of the fluid.
    (Please refer to the "Material Selection table" listed in the catalog. If you are unable to find your desired operating conditions or what is not listed in the "Material Selection table", contact our sales representative.)
