Válvula de mariposa con brida | Operado por engranaje helicoidal | Acero inoxidable + Asiento de EPDM | DN50-DN2000 | Industrial & Tratamiento de agua

Descripción general del producto

ElVálvula de mariposa con brida es un alto rendimiento, manually operated flow control valve designed for reliable on/off and throttling service in industrial, tratamiento de agua, and pharmaceutical piping systems. Featuring a rugged flanged connection for secure, leak-proof installation, this valve is manufactured from premium stainless steel with a worm gear operator that provides exceptional corrosion resistance, smooth operation, and precise control in demanding environments. The EPDM seat ensures bubble-tight shut-off across a wide temperature range, making it suitable for water, aire, and mild chemical applications. The worm gear mechanism provides mechanical advantage, allowing easy operation even with large-diameter valves. Available in sizes from DN50 to DN2000 with flanged connections conforming to international standards, this valve is ideal for water supply networks, plantas de tratamiento de aguas residuales, industrial process lines, and pharmaceutical manufacturing facilities. This valve is the trusted choice for engineers and plant operators worldwide.

Especificaciones técnicas

Válvula de mariposa con brida

Características clave

• 1. Flanged Connection – Secure, Leak-Proof Installation
• 2. Construcción de acero inoxidable de primera calidad: resistente a la corrosión & Durable
• 3. Worm Gear Operator – Effortless Operation for Large Diameters
• 4. EPDM Seat – Bubble-Tight Sealing
• 5. Wide Size Range – DN50 to DN2000
• 6. 3-Year Warranty – Long-Term Reliability

Working Principle

• 1. Operación: 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.

Preguntas frecuentes

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

A: 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?

A: 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?

A: The operating temperature range for the EPDM (Ethylene Propylene Diene Monomer) seat is -20°C to +120°C. It offers excellent resistance to water, clima, ozono, 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?

A: Sí. Butterfly valves are suitable for throttling (regulación de flujo) aplicaciones. 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.
