Product Overview
The HN62 Forged Globe Valve is a compact EN/DIN globe valve series for smaller pipe sizes and higher pressure ratings. It is intended for shut-off and selected throttling service where forged valve construction, compact dimensions and DN/PN compatibility are required.
Typical applications include steam systems, utility lines, oil and gas service, chemical processing, petrochemical auxiliary lines and general industrial pipelines using compatible fluids.
HN62 covers DN15 to DN50 with PN16 to PN160 pressure classes. Connection options include EN 1092-1 flanged ends and project-dependent butt-welded ends. Final configuration should be confirmed according to pressure, temperature, medium and project requirements.
Key Features
- Forged compact construction: Suitable for small-bore industrial service where compact valve dimensions are required.
- High pressure range: Covers PN16, PN25, PN40, PN63, PN100 and PN160 configurations according to source catalog data.
- Globe valve flow path: Designed for shut-off and selected throttling operation when specified for the operating conditions.
- Rising rotating stem: Source catalog describes a rotating, rising stem structure.
- Flanged or butt-welded ends: Connection type can be selected according to installation requirements.
- Multiple disc options: Plug, needle and parabolic disc options may be considered for project-specific service conditions.

Frequently Asked Questions
Q: How is HN62 different from HN61?
HN62 is a compact forged globe valve series covering DN15-DN50 and up to PN160. HN61 covers larger EN/DIN sizes and is used for more general industrial globe valve service.
Q: Can HN62 be supplied with butt-welded ends?
Yes. The source catalog lists butt-welded connections according to EN 12627 as well as flanged ends according to EN 1092-1 or project requirements.
Q: Are actuator options available?
Manual handwheel operation is standard. Electric actuator options and ISO 5210 actuator-ready configuration may be discussed based on project requirements.
