FAQ

Q: What are the core materials of sanitary clamp check valves, and how to select them?

A: The standard material for sanitary clamp check valves is SUS304 stainless steel, suitable for general food and beverage applications.For high-cleanliness, acid and alkali resistant applications (such as pharmaceutical and bioengineering), SUS316L stainless steel is recommended (the first choice for pharmaceutical and bioengineering).

The valve disc and spring are both made of 316L stainless steel.Seal options:

● EPDM: resistant to steam, suitable for SIP sterilization

● PTFE: resistant to strong acids, alkalis and high temperature

● FKM (Viton): resistant to oil media

All seals comply with FDA & 3-A sanitary certifications.

Q: What are the key technical parameters of sanitary clamp check valves?

A:

● Nominal diameter: DN15–DN100

● Nominal pressure: 1.0 MPa / 1.6 MPa

● Working temperature (depends on seal):

o EPDM: -10 °C ~ 150 °C

o PTFE: -30 °C ~ 220 °C

● Inner surface finish: Ra ≤ 0.4 μm (electropolished)

● Cracking pressure: standard 0.02 MPa

● Low / high cracking pressure can be customized as required.
