Pressure Seal Gate Valve
Self-energizing bonnet gate valve for high-pressure steam and feedwater isolation. Seal tightness increases with line pressure rather than depending on bolt load.

Datasheets
Each product page carries the full datasheet content: technical data with the basis for each parameter, design features, part material table, standards with their scope, dimensions, inspection scope and the document list.
PDF datasheets are pending. They will be generated from the same structured
data file that drives the product page, so the two cannot diverge. Until then, the product
page is the datasheet - and it is more current than any PDF will ever be.
Pressure Seal Globe Valve
Self-energizing bonnet globe valve for tight shut-off and controlled throttling in high-pressure steam, drain and vent service.

Pressure Seal Check Valve
Non-return valve with a self-energizing cover joint. Swing type for low-loss service, piston lift type where fast closure and stability matter more than pressure drop.

Open datasheet
Forged Power Plant Check Valve
Check valves with a one-piece forged pressure boundary for power station duty, in both pressure seal and bolted cover arrangements depending on class.

Main Steam Valve
Isolation on the hottest, highest-pressure line in the plant. Material grade - not valve type - is the first selection decision here.

Open datasheet
Feedwater Valve
Isolation and non-return on the feedwater circuit - the highest-pressure water service in the plant, with cavitation and flashing as the dominant wear mechanisms.

Extraction Steam Check Valve
Non-return protection on turbine extraction lines. The design case is not normal operation - it is what happens in the two seconds after a turbine trip.

Open datasheet
Stop-Check Valve
A globe body where the disc is free to lift under forward flow but can be screwed down to isolate. Two functions, one pressure boundary, one flange pair.
