Flange Type Butterfly Valve

Description

KELOR Flange Type Butterfly Valve Manufacturer

KELOR Flange Type Butterfly Valve is engineered for high performance and reliability across diverse pipeline systems, ensuring uninterrupted flow control in industrial, commercial, and utility-grade applications. Designed in compliance with API 609 and MSS-SP-67 standards, this flange type butterfly valve features a rugged cast body with precision-machined flanged ends, ensuring secure bolting, accurate alignment, and leak-tight performance.

Its compact face-to-face design allows easy installation in tight piping layouts, while the centrally mounted disc ensures uniform sealing and reduced operating torque. The valve is suitable for both on/off and throttling services where consistent performance and durability are required.

Available in a wide size range from DN 50 to DN 1200, the KELOR flange type butterfly valve supports working pressures up to 150 psi. Multiple actuation options are available including manual lever, worm gearbox, pneumatic actuator, and electric actuator, making it adaptable for manual as well as fully automated flow control systems.

The valve is ideally suited for water distribution networks, HVAC systems, fire protection lines, chemical processing units, and low-pressure gas pipelines. KELOR’s design emphasis on precision sealing and material integrity ensures reliable performance even under continuous duty cycles.

KELOR manufactures flange type butterfly valves using high-quality materials such as Ductile Iron, Carbon Steel, and Stainless Steel (CF8 / CF8M). These materials provide excellent corrosion resistance, mechanical strength, and compatibility with a wide range of flow media. For superior sealing performance, a variety of seat and liner options are available including EPDM, NBR, Viton, Hypalon, Silicone, and PTFE.

An ISO 5211 compliant mounting pad allows direct mounting of standardized actuators without additional brackets, enabling easy automation. Each valve undergoes stringent quality checks, hydrostatic testing, and leakage testing to ensure long-term durability and bubble-tight shut-off.

As a trusted manufacturer, supplier, and exporter, KELOR delivers flange type butterfly valves that meet global quality expectations, making them suitable for municipal projects, industrial plants, and export-oriented applications worldwide.
