• 1. Kena caka: Turning the handwheel rotates the worm gear, which drives the valve stem. The stem rotates the disc 90° from fully closed to fully open.
• 2. Self-Locking: The worm gear mechanism is self-locking — the valve stays in position without external locking devices, even under flow pressure.
• 3. Flow Control: The disc rotates between 0° (fully closed) and 90° (fully open), with intermediate positions for throttling control.

FAQ

Q1.: What is the difference between a flanged butterfly valve and a wafer-style butterfly valve?

KEI: Flanged butterfly valves feature integral flange ends and connect directly to pipeline flanges using standard gaskets and bolts; they offer the most robust and durable connection, are easy to install and maintain, and are suitable for high-pressure and critical applications. Wafer-style butterfly valves are clamped between two flanges using through-bolts; they are lighter, more compact, and more cost-effective. This product is a flanged butterfly valve.

Q2.: What is the difference between worm gear operation and lever operation?

KEI: Worm gear operation utilizes a worm gear mechanism to provide mechanical advantage, resulting in low operating torque and effortless handling; it is suitable for large-diameter valves (DN100 and above). The worm gear mechanism features a self-locking function that prevents accidental valve closure. Lever operation is simpler and more economical, suitable for small-diameter valves (below DN100). This product features worm gear operation.

Q3.: What is the temperature range for the EPDM seat?

KEI: The operating temperature range for the EPDM (Ethylene Propylene Diene Monomer) seat is -20°C to +120°C. It offers excellent resistance to water, weather, ozone, and aging, but is not recommended for use with petroleum-based oils or strong acidic media.

Q4.: Can this butterfly valve be used for throttling?

KEI: Io. Butterfly valves are suitable for throttling (lawatu ni drodro) applications. The concentric design provides linear flow characteristics, making it ideal for flow control. The disc can be positioned at any angle between 0° and 90° to achieve precise flow regulation.
