Gate Valve HN64

Gate valve HN64 is an EN/DIN wedge gate valve for industrial shut-off service, available from DN50 to DN1000 with PN16 to PN100 pressure ratings. It is suitable for water, steam, air, selected chemical media, petrochemical pipelines, mining and metallurgical service where full-open or full-closed isolation is required.

SKU: HN64-GTV Categories: ,

Product Overview

The HN64 Gate Valve is an EN/DIN industrial wedge gate valve designed for pipeline isolation service. It is used where the valve normally operates either fully open or fully closed, helping provide low flow resistance through the pipeline when open.

HN64 is available in a broad DN50-DN1000 size range and pressure ratings from PN16 to PN100. Depending on project requirements, the valve can be supplied with flanged or butt-welded ends, handwheel operation, gearbox operation or actuator-ready top flange configuration.

Typical applications include industrial water, drinking water, steam, air, non-aggressive chemical service, petrochemical and refinery pipelines, mining service and metallurgical process lines. Final material selection should be confirmed according to pressure rating, operating temperature and fluid compatibility.

Key Features

  • Wedge gate valve design: For shut-off pipeline isolation service.
  • Rising, non-rotating stem: Provides clear valve position indication.
  • Suitable for fully open or fully closed operation: Not intended for throttling service.
  • Available with flanged or butt-welded end connections: EN 1092-1 flanged and EN 12627 butt-welded options.
  • DN50-DN1000 range: With PN16, PN25, PN40, PN63 and PN100 options.
  • Handwheel, gearbox and actuator-ready configurations: May be selected according to valve size and project requirement.
  • Carbon steel, alloy steel and stainless steel body material options: Available depending on service condition.

Pressure-Temperature Reference

Working pressure varies by material grade and operating temperature. The following EN 12516-1 reference values are listed in MPa for preliminary selection only. The catalog P-T table provides PN16/PN25/PN40 data. For PN63/PN100 project conditions, confirm allowable pressure-temperature values against the approved material standard and project datasheet.

FAQ

What is HN64 used for?

HN64 is used for industrial shut-off and pipeline isolation service, especially where the valve is normally operated fully open or fully closed.

What is the size and pressure range?

The catalog range is DN50-DN1000 with PN16 to PN100 pressure ratings. Available sizes vary by pressure rating, so final selection should follow the dimension table and project datasheet.

Can HN64 be supplied with an actuator?

Yes. Handwheel operation is common, while gearbox or electric actuator configurations may be selected according to valve size, torque and project requirement.

Is HN64 the same as HN63?

No. HN63 is a flanged gate valve in a lower pressure range. HN64 covers a wider PN16-PN100 gate valve range and includes both flanged and butt-welded connection options.
