Versatile Material Choices for Optimal Durability

Select between stainless steel or ductile iron discs and EPDM, NBR, or PTFE seats to match application requirements. This flexibility ensures resistance to corrosion and compatibility with various media, increasing operational longevity and minimizing maintenance needs.

Compliance with International Standards

The valve complies with EN593, ISO 5752, and EN 558 Series 20 standards for face-to-face dimensions and end connections. Available with ISO PN10/PN16 and ANSI150 flanges, it fits into diverse industrial systems, ensuring global interoperability and quality assurance.

Advanced Coating and Customization

A robust fusion-bonded epoxy coating enhances the valve's resilience against environmental factors, while the body color can be tailored upon request to fit specific branding or identification needs. This guarantees both reliability and aesthetic flexibility.

FAQ's of Concentric Butterfly Valve:

Q: How can I select the best disc and seat material for my application?

A: The choice between stainless steel and ductile iron discs, as well as EPDM, NBR, or PTFE seats, depends on the media handled and environmental conditions. Stainless steel and PTFE offer higher corrosion resistance for aggressive or high-purity fluids, while ductile iron and EPDM/NBR are cost-effective for water and non-corrosive liquids.

Q: What are the benefits of using a concentric butterfly valve in fluid control systems?

A: Concentric butterfly valves provide efficient flow regulation with minimal pressure drop, bubble-tight sealing (Class VI), and quick operation. Their compact design and various actuation options make them highly adaptable for installations where space and accessibility are factors.

Q: When should I use lever, gearbox, or actuator operation types?

A: Levers are suitable for manual, low-torque applications and smaller sizes. Gearboxes provide easier manual control for larger or higher-pressure valves. Actuators-electric or pneumatic-should be chosen for automated processes or remote operation requirements.

Q: Where can the concentric butterfly valve be installed?

A: These valves are designed for water, air, oil, and other non-corrosive liquid systems in industrial, municipal, and HVAC applications. With a wide pressure and temperature range and compatibility with multiple connection standards, they can be integrated into numerous systems worldwide.

Q: What is the process for installing this valve?

A: The valve can be installed between flanges (wafer or lugged connections) following EN 558 Series 20 face-to-face and ISO/ANSI flange standards. Proper alignment, correct torque, and verification of seal integrity (Class VI) ensure reliable operation. Always adhere to manufacturer's guidelines for the chosen actuation type.

Q: How does the fusion-bonded epoxy coating benefit the valve?

A: Fusion-bonded epoxy provides excellent protection against corrosion and chemical attack, prolonging valve life and maintaining performance even in challenging environments. It is especially advantageous in water treatment and outdoor installations.
