Versatile Disc and Seat MaterialsThe IVTL Butterfly Valve offers a choice between ductile iron or stainless steel discs, paired with EPDM, NBR, or PTFE seat options. This adaptability enables reliable operation with a variety of process media-whether water, oil, gas or air-across industrial and water treatment plant settings.
Corrosion-Resistant CoatingEquipped with Fusion Bonded Epoxy (FBE) body coating, this valve provides enhanced resistance to abrasion and corrosion. The FBE coating is particularly advantageous for water treatment plants and industrial sites, prolonging the valve's service life and maintaining operational integrity.
Flexible Operation and End ConnectionsThe IVTL Butterfly Valve is available with lever, gear, or actuator operation, suiting manual or automated control needs. It features flanged ends built to ISO 7005-2/EN1092 standards and a wafer-type design, simplifying installation and maintenance across port sizes from 40 mm to 600 mm.
FAQ's of IVTL Butterfly Valve IVGKL/ IVGK/ IVGK-25:
Q: How is the IVTL Butterfly Valve IVGKL/IVGK/IVGK-25 installed in a piping system?
A: Installation involves mounting the wafer-type valve between flanged pipe ends using bolts according to ISO 7005-2 or EN1092 standards. Ensure alignment of the disc with the pipeline for optimal sealing and functionality.
Q: What media can this butterfly valve handle safely?
A: This valve is suitable for water, air, oil, and gas, supported by its seat and disc material options (EPDM, NBR, PTFE, ductile iron, stainless steel). Select the appropriate seat material based on the media's chemical composition for best results.
Q: When should I consider using gear or actuator operation instead of a lever?
A: Choose gear or actuator operation for larger port sizes (above 200 mm), higher operating pressures, or remote/automated valve control requirements. Lever operation suits manual, low-pressure, and smaller diameter applications.
Q: Where is the IVTL Butterfly Valve most beneficial?
A: This valve excels in industrial and water treatment plant environments, particularly where corrosion resistance and reliable sealing (Class VI leakage) are priorities. It adapts well to facilities requiring strict standards and variable process conditions.
Q: What is the benefit of Fusion Bonded Epoxy coating?
A: Fusion Bonded Epoxy (FBE) coating protects the valve's cast iron body from rust, chemicals, and abrasion, significantly enhancing longevity and reducing maintenance needs, especially in water treatment and corrosive industrial settings.
Q: How does the design standard EN 593 affect valve performance?
A: Adherence to EN 593 ensures the valve meets rigorous European performance and safety criteria, providing reliable sealing, robust operation, and compatibility with international industrial systems.
Q: What range of port sizes is available for this valve?
A: The IVTL Butterfly Valve is offered in port sizes ranging from 40 mm to 600 mm, enabling its use in small pipelines as well as large-scale industrial applications.
