Kimray 36 FWA

What pressure, flow and temperature is it rated for?

This unit is rated for 125 psig maximum working pressure with a Cv range from 11.5 to 93.3. Temperature rating is not specified in the listing; ask the seller for the temperature range qualified for your service fluid. Weight-operated control valves like this are typically rated for temperatures based on elastomer and packing material selection.

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

The listing states this valve is suitable for liquid and gas process fluids, and NACE MR0175 option is available for sour service applications containing H2S. Oxygen cleaning status is not mentioned; ask the seller whether it has been cleaned to CGA G-4.1 or equivalent if you need it for oxygen service. Weight-operated valves are commonly used for natural gas, propane, air, nitrogen, and other non-corrosive gases when materials are appropriately selected.

What materials are the wetted parts?

The body is cast ductile iron, and the listing specifies linear trim but does not detail the trim material or elastomers. Ask the seller for the complete material specification including trim, seat, and packing materials. Kimray typically offers trim options in stainless steel and other alloys depending on service requirements.

What should I inspect before putting it into service?

Verify the Class VI shutoff rating by bench testing for seat leakage, inspect the weight mechanism for free movement and corrosion, and check all packing for compression and integrity. Examine the trim for erosion or damage, confirm the body and flanges have no cracks or corrosion (especially if previously in sour service), and verify the Cv matches your application by checking the installed trim size. Replace all elastomers and packing as standard practice on used control valves unless recent service records confirm their condition.
