API Cast Steel Globe Valve HN102

Product Overview

The HN102 API Cast Steel Globe Valve is designed for shut-off and selected throttling service in ANSI pipeline systems. The globe valve body pattern provides a guided disc and seat arrangement suitable for controlled flow regulation, isolation and pressure-containing industrial service.

This valve series is suitable for oil, gas, steam, water, petrochemical, refinery, power plant and general industrial pipeline applications where API and ASME specifications are required. Available pressure classes include Class 150, 300, 600, 900, 1500 and 2500, with size availability depending on pressure class and selected end connection.

HN102 can be supplied with raised face, butt-welded or ring type joint end configurations according to pressure class, piping design and project specification. Material options include carbon steel, Cr-Mo alloy steel and low-temperature carbon steel grades.
