THD Shank 1" Diverter Valve — 845.0 Plug

What pressure, flow and temperature is it rated for?

The listing specifies a capacity of 845.0 but does not indicate the unit of measure or whether this refers to pressure, flow, or another parameter. You'll need to ask the seller for the pressure rating, flow coefficient (Cv), and temperature range. Plug-type diverter valves in this size are commonly rated for pressures from 150 to 600 psi, but the actual rating depends on the body and end connection design.

What materials are the wetted parts?

The body is bronze construction as stated. The listing does not identify the materials for the plug, seat, stem, or seals. Bronze valves typically use bronze or stainless steel trim with elastomer or PTFE seals, but you should confirm the specific alloy and seal materials with the seller, particularly if compatibility with your process gas is critical.

What should I inspect before putting it into service?

Verify the seat and plug sealing surfaces for scoring, galling, or erosion, and check that the plug rotates smoothly through its full travel without binding. Inspect all seals and packing for hardening, cracking, or compression set, especially on surplus units that may have been in storage. Pressure test to the rated working pressure and perform a seat leakage test to confirm shutoff performance meets your requirements.
