Kimray 212 SGT BP

What pressure, flow and temperature is it rated for?

This unit is rated for 175 psig maximum working pressure with a set point range of 5 to 125 psig. The Cv range is 6.9 to 52 with a flow coefficient (Cf) of 0.75. Temperature rating is not specified in the listing; ask the seller for the temperature limits of the installed trim and elastomer components.

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

The unit is configured for gas service, but the specific process gas is not identified in the listing. Oxygen cleaning status is not stated. Back pressure regulators used in oxygen service require special cleaning and materials certification; if you need oxygen compatibility, confirm cleaning documentation and verify NACE MR0175 configuration if handling sour gas.

What materials are the wetted parts?

The body is cast ductile iron with 2" equal percentage trim, but specific materials for the trim, seat, diaphragm, and seals are not listed. Ask the seller for a complete bill of materials including elastomer specifications, particularly if you're handling corrosive gases or need NACE MR0175 compliance for sour service.

What should I inspect before putting it into service?

Verify Class VI shutoff performance with seat leakage testing, inspect the diaphragm and pilot system for tears or corrosion, and check all elastomers for hardening or cracking. Confirm the pneumatic pilot responds correctly across the 5-125 psig set point range, examine the body and trim for erosion or pitting, and pressure test to 175 psig to verify integrity of the castings and connections.
