High Pressure Gate Valve
Full-bore isolation at high pressure. Bolted bonnet where the class allows it and maintenance access matters, pressure seal where it does not.

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.
High Pressure Globe Valve
Tight shut-off and the only construction here that tolerates throttling. Standard on drains, vents, warm-up and bypass lines.

Open datasheet
High Pressure Check Valve
Non-return protection where the governing question is not the rating but how fast the valve closes when flow reverses.

Open datasheet
Forged Gate Valve
Gate valve with the pressure boundary formed from a single forged billet. Chosen where thermal cycling or wall thickness makes casting soundness the risk.

Open datasheet
Forged Globe Valve
Globe valve with a one-piece forged pressure boundary. The construction of choice where the valve throttles and cycles at high pressure.

Open datasheet
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.

Open datasheet
Pressure Seal Globe Valve
Self-energizing bonnet globe valve for tight shut-off and controlled throttling in high-pressure steam, drain and vent service.
12 parameters · 15 parts · 7 standards
Open datasheet
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.
11 parameters · 12 parts · 6 standards
Open datasheet
Forged 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.

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.
