Common Questions

Can I use this on steam?

97FB-CIB 4 is listed by Watts for steam and liquid service. Its 200 psi WOG rating is a cold-service number, not the steam limit -- check the spec sheet for the WSP rating at your operating temperature.

Does it have a blowoff / blowdown port?

Yes. The retainer cap/cover is tapped for a blowoff connection, so you can flush accumulated debris by pulling the plug or piping a blowdown valve to it -- no need to break the strainer apart. The closure plug is included.
