Kimray 212 SMT DB PO

What pressure, flow and temperature is it rated for?

This regulator has a maximum working pressure of 400 psig and a flow coefficient ranging from 8.5 minimum Cv to 23.3 maximum Cv with a Cf of 0.79. No temperature rating is provided in the listing—contact the seller for the temperature range or consult the catalog page 04:10.1 if available.

What gases is it compatible with, and has it been oxygen cleaned?

The listing indicates this unit is suitable for both liquid and gas process fluids but does not specify which gases or whether oxygen cleaning has been performed. Back pressure regulators like this are commonly used in natural gas, hydrocarbon, and general industrial gas applications—confirm compatibility with your specific fluid and any required cleaning or material certifications with the seller, particularly if you need NACE MR0175 compliance.

What materials are the wetted parts?

The body is cast ductile iron and the trim is 1.5" linear type, but the listing does not specify elastomer materials, seat materials, or other wetted component metallurgy. Request a full materials list from the seller, especially if you require specific elastomers for chemical compatibility or metal grades for corrosive service.

What should I inspect before putting it into service?

Inspect the seat and trim for erosion or scoring, verify the pneumatic actuator holds pressure and cycles smoothly from 10 psig crack open to 35 psig full open, and confirm the Class VI shutoff rating by testing for seat leakage. Check all NPT threads and gasket surfaces for damage, verify spring condition, and test the fail-closed function by bleeding supply gas—wear or contamination from previous service can compromise performance even if the unit appears intact externally.
