Absperrschieber aus Stahlguss provide isolation for industrial pipelines that need low flow resistance when fully open. Farpro offers wedge gate valve configurations for water, Dampf, 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.
Arten von Absperrschiebern aus Farpro-Gussstahl
Messerschieber aus Stahlguss – Z73

Elektrischer Keilschieber aus Stahlguss – Z941H
Ein elektrischer Keilschieber, auch als elektrisch betätigter Keilschieber bekannt, ist ein Ventiltyp, der für den Betrieb konzipiert ist
Keilschieber aus Stahlguss – Z40H, Z41H und Z541
Das Sortiment an Keilschiebern aus Stahlguss von Farpro umfasst den Z41H, Z40H, Z541- und SZ41H-Serie. These valves use a wedge-shaped gate to isolate the pipeline
How Cast Steel Gate Valves Work
The gate moves perpendicular to the flow. Bei vollständiger Öffnung, it retracts from the flow path; wenn geschlossen, 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.
- Körper, trim and sealing materials.
- Handbuch, 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.
Anwendungen von Farpro-Schieberventilen aus Gussstahl
Cast steel gate valves are commonly considered for process and utility isolation in oil and gas, Petrochemie, 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, trimmen, 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 Durchgangsventil or control valve instead of using an isolation gate valve partially open.
Wartung und Reparatur von Farpro-Schieberventilen aus Gussstahl
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, Druckklasse, Anschlüsse und Bedienung. A well-defined specification makes quotations easier to compare and helps avoid installation mismatches.
