BW Herose 4" Extended Stem Globe Valve — 11.0 PSIG

What pressure, flow and temperature is it rated for?

This valve is rated for 11.0 PSIG. Flow capacity and temperature rating are not specified in the listing; ask the seller for the nameplate data or manufacturer documentation. Herose 278 valves are typically low-pressure cryogenic service valves, and flow capacity for a 4" globe valve depends on the specific trim and Cv rating.

What materials are the wetted parts?

The listing specifies stainless steel construction but does not detail the specific wetted materials or grades. Ask the seller for body material specification, seat material, and packing type, as these vary by application and cryogenic compatibility requirements.

What should I inspect before putting it into service?

Since this valve was not physically verified at inventory, conduct a full visual and functional inspection including stem straightness and thread condition (critical on extended stems), packing integrity, seat tightness under pressure test, and body/bonnet for cracks or weld repairs. Extended stem valves are vulnerable to stem damage during transport or storage, and cryogenic service demands leak-tight seats and appropriate packing materials for thermal cycling.
