Double Flanged Butterfly Valve EPDM Liner, Suited for PN16 Flanges

This doubleflanged butterfly valve is engineered for reliable performance and long service life in systems that demand secure installation and consistent flow control. Designed to bolt directly between PN16 flanges, it combines a durable ductile iron body, a flexible EPDM liner, and precisionmachined components to ensure smooth operation and a tight shutoff in a wide range of water and HVAC applications.

Technical Data:

• Body Material: Epoxycoated ductile iron for superior strength and corrosion resistance
• Disc Material: Ductile iron, engineered for balanced operation and longterm durability
• Seat / Liner Material: EPDM (ethylenepropylenediene rubber) liner, offering excellent sealing properties, chemical resistance to waterbased fluids, and a temperature range of approximately 10°C to +120°C
• Connection Type: Doubleflanged body designed for direct installation between PN16 flanges
• Pressure Rating: PN16 (up to 16bar nominal), suitable for mediumpressure systems
• Temperature Range: 10°C to +120°C, aligned with EPDM performance standards
• Mounting Interface: ISO5211 top mounting pad for direct connection to manual gearboxes or future automation with electric or pneumatic actuators
• Sizes Available: Typically available from DN80 (3") to DN300 (12"), with other sizes on request

Key Features:

• Robust DoubleFlanged Design: Provides secure, vibrationresistant installation with full mechanical support between flanges
• EPDM Liner for Tight Sealing: Ensures reliable shutoff and excellent resistance to water, air, and mild chemicals
• LowTorque Operation: Smooth actuation and reduced wear on components extend service life and improve handling
• ActuatorReady Interface: ISO5211 mounting pad enables simple upgrade to automated control without replacing the valve
• CorrosionResistant Finish: The epoxy coating protects against environmental degradation and fluidborne corrosion
• MaintenanceFriendly Construction: Bolted flange design allows for easy inspection, replacement, or maintenance without complex disassembly

Typical Applications:

• Chilled and hotwater circuits in HVAC systems
• Water treatment plants and industrial water supply systems
• Pumping stations and process lines requiring isolation valves
• Plantrooms or mechanical systems using PN16 flange standards
• Distribution networks where secure bolted joints and longterm reliability are critical

Summary:
This doubleflanged butterfly valve with EPDM liner provides a perfect balance of strength, sealing integrity, and versatility. Its ductile iron body and precision EPDM seat ensure dependable operation under pressure, while the ISOready top mount makes it futureproof for automated control. Ideal for water, air, and HVAC systems, it offers the performance and durability needed for modern engineered installations.
