Precision Engineering & Standards Compliance

Each Flanged Butterfly Valve is manufactured with rigorous attention to international standards, including ISO 5752 for face-to-face dimensions and both EN 1092 and ANSI B16.5 for end connections. The robust fusion bonded epoxy coating enhances corrosion resistance, making these valves ideal for demanding applications in various industries.

Versatility in Operation and Application

Whether operated manually via lever or gear, or with pneumatic/electric actuators, these butterfly valves are tailored for easy integration into water supply, HVAC, fire protection, and irrigation setups. Their adaptable disc and seat materials extend compatibility with water, gas, oil, and non-aggressive mediums, ensuring effective isolation and fluid control.

FAQ's of Flanged Butterfly Valves:

Q: How do the disc and seat materials affect the valve's performance in different applications?

A: The disc options-stainless steel or epoxy-coated cast iron-provide corrosion resistance and strength, suitable for water, oil, and gas applications. Seat materials such as EPDM, NBR, and PTFE ensure compatibility with various media, offering excellent sealing for Class VI bubble-tight shutoff performance. Selecting the right combination ensures optimal durability and suitability for your specific process conditions.

Q: What is the maximum pressure and temperature these flanged butterfly valves can handle?

A: Our flanged butterfly valves are rated for pressure classes PN10 and PN16 (10-16 bar) and are designed to operate reliably within a working temperature range of -10C to 120C, making them suitable for most water, HVAC, fire protection, and irrigation networks.

Q: When should I choose manual, gear, pneumatic, or electric actuation for these valves?

A: Manual lever or gear operation is ideal for small to medium-sized valves where frequent adjustments aren't necessary. Pneumatic and electric actuators are recommended for larger valve sizes (above 200 mm), or where remote, automated, or frequent operation is required, improving safety and operational efficiency.

Q: Where can these flanged butterfly valves be installed?

A: These valves are suitable for use in water supply, HVAC, fire protection, and irrigation systems, as well as in pipelines carrying water, gas, oil, or other non-aggressive fluids. Their robust construction and conforming flanged connections ensure compatibility with global pipeline standards and installation in industrial, commercial, or municipal infrastructures.

Q: What is the process for ensuring leak-proof performance in these butterfly valves?

A: Each valve undergoes stringent quality checks to meet Class VI leakage standards, ensuring bubble-tight shutoff. This is achieved with finely engineered disc-seat interfaces and premium sealing materials such as EPDM, NBR, or PTFE, all tested according to international leakage and pressure norms.

Q: What benefits do fusion bonded epoxy paint and robust construction materials provide?

A: Fusion bonded epoxy paint and high-quality cast iron/ductile iron construction guard against corrosion and mechanical wear, extending service life. This makes the valves suitable for harsh and high-moisture environments without compromising their mechanical integrity or operational reliability.
