Vannes à vanne en acier moulé provide isolation for industrial pipelines that need low flow resistance when fully open. Farpro offers wedge gate valve configurations for water, vapeur, oil and other compatible services.
This page explains how to select the valve family. For individual models, materials and quotation details, view our Z40H, Z41H and Z541 cast steel wedge gate valves.

Vannes à guillotine en acier moulé – Z40H, Z41H et Z541
La gamme de vannes à guillotine en acier moulé de Farpro comprend le Z41H, Z40H, Séries Z541 et SZ41H. These valves use a wedge-shaped gate to isolate the pipeline
How Cast Steel Gate Valves Work
The gate moves perpendicular to the flow. Lorsqu'il est complètement ouvert, it retracts from the flow path; une fois fermé, it contacts the seats to isolate the pipeline. Standard gate valves are intended for fully open or fully closed service, rather than continuous throttling.
What to Specify Before Ordering
- Valve size and connection standard.
- Design and operating pressure and temperature.
- Fluid, including any corrosive constituents or solids.
- Corps, trim and sealing materials.
- Manuel, gear-operated or actuated operation.
- Required design, inspection and documentation standards.
Nominal pressure or class should be checked with the selected material’s pressure-temperature rating. A class designation is not a single pressure that applies at every temperature.
Applications des vannes à vanne Farpro en acier moulé
Cast steel gate valves are commonly considered for process and utility isolation in oil and gas, pétrochimique, power generation and water systems. The suitable model depends on the complete duty, rather than the industry name alone.
For steam, assess pressure and temperature together. For chemical fluids, evaluate body, garniture, packing and gasket compatibility. For solids or slurry, consider whether a different valve geometry is more suitable.
Where regular flow adjustment is required, compare an appropriate robinet à soupape or control valve instead of using an isolation gate valve partially open.
Entretien et réparation des vannes à vanne Farpro en acier moulé
Plan inspection around the valve duty and the manufacturer’s maintenance instructions. Check external leakage, stem operation, packing condition and the required operating clearance.
Before opening a valve body or removing it from the pipeline, qualified personnel must isolate the equipment, control hazardous energy, release trapped pressure and verify the safe condition under the site’s approved procedure. Apply lubrication only to the locations and with the products specified for that valve.
For replacement parts or a replacement valve, send the model, identification details, dimensions and service conditions to Farpro. Read our industrial valve replacement guide for procurement and planning considerations.
Choose a Configuration for Your Project
Start with the function and operating conditions, then compare material, pressure class, connexions et fonctionnement. A well-defined specification makes quotations easier to compare and helps avoid installation mismatches.
