Complete Valve Portfolio for Industrial Piping Systems

Whether isolating, regulating, protecting, or monitoring – FERGO provides technically advanced valve solutions tailored to your process medium and operating conditions:

  • Isolation Valves: High-quality globe valves (including angle seat design) for tight shut-off in steam, gas, or liquid systems. Gate valves provide minimal pressure loss in applications with infrequent operation. Knife gate valves are designed for viscous, abrasive, or solids-containing media such as slurry or bulk materials.
  • Ball valves: Available in 2-way and 3-way configurations with threaded, flanged, or welded ends. Body materials include stainless steel (1.4408 / CF8M), carbon steel, ductile iron, duplex stainless steel, or PFA-lined versions for aggressive chemicals.
  • Control Valves: Precision needle valves for accurate flow adjustment in laboratory, instrumentation, or gas control applications.
  • Steam Traps: Original GESTRA steam traps – BK (thermostatic), MK (membrane), and UNA (float type) – for efficient condensate discharge in steam systems.
  • Sight glasses: For visual inspection of flow and tank processes, available in stainless steel or PFA-lined versions with borosilicate glass according to DIN 7080.
  • Strainers: Protect downstream equipment from debris. Available in brass, stainless steel, cast iron, or PFA-lined designs with various mesh sizes.

Automated Valves for Process Integration

For modern process control systems, FERGO supplies automated ball valves and butterfly valves equipped with pneumatic (single-acting or double-acting) or electric actuators. Complete automation assemblies include NAMUR solenoid valves, limit switch boxes, inductive sensors, and positioners – fully assembled, tested, and ready for operation.

Technical Documentation and Engineering Support

Each valve is supplied with detailed technical data sheets including pressure-temperature ratings, dimensions, and material specifications. 3D CAD STEP models are available on request to simplify integration into your design and engineering workflow.

Customized Valve Solutions with Fast Delivery

Beyond standard configurations, FERGO manufactures special designs using duplex or super duplex materials, extended stems, special flanges, FDA-compliant or high-temperature sealing systems, and individually configured knife gate valves with scrapers or flushing ports.

With over 25,000 valves in stock, many products are dispatched on the day of order. Our experienced technical specialists provide professional consultation to ensure optimal valve selection or develop fully customized industrial valve solutions.
