Selecting the Ideal Connection Type: Clamp, Threaded, or Flanged


Correct check valve selection depends on the process connection, installation space, cleaning method, pressure and maintenance requirements. Buyers should evaluate these factors together with the application conditions to confirm the most suitable sanitary check valve configuration. Choose clamp connections for quick removal and cleaning, threaded versions for compact piping and flanged models for robust mechanical installation.

FAQs about Sanitary Check Valve

How does a sanitary check valve differ from a sanitary ball valve?

A sanitary check valve operates automatically to prevent reverse flow. A sanitary ball valve is actively opened or closed for line isolation, diversion or flow control. They should not be treated as interchangeable products.


How often should a sanitary check valve be inspected?

Inspection frequency depends on service conditions, cleaning cycles, medium properties and operating hours. Check the seat, spring, seals and closure element for wear, deposits or damage during scheduled line maintenance.


Can a sanitary check valve handle liquids containing solids?

It depends on particle size, concentration, valve geometry and opening pressure. Solids may obstruct the closure element or seat, so the medium and cleaning method should be reviewed before model selection.
