Product Q&A

Q:How to select the right butterfly valve for water supply and industrial systems?

For water supply, HVAC, and industrial pipelines, resilient seated butterfly valves are recommended for compact design, lightweight, and quick quarter-turn operation. Consider pressure rating (PN10/PN16), disc and seat materials, and throttling control for optimal performance and long service life.

Q:What makes butterfly valves ideal for fire protection and large pipeline applications?

Butterfly valves are ideal for fire protection and large-diameter pipelines. Their compactness, low weight, and quick operation make them suitable for space-limited installations and main water lines. Full-flow design minimizes pressure drop, while resilient seats ensure reliable shutoff.

Q:Are butterfly valves suitable for frequent operation and automated systems?

Yes. Butterfly valves excel in high-frequency operation and automation due to their quarter-turn mechanism. Equipped with electric or pneumatic actuators, they provide fast response and precise control. Durable resilient seated designs ensure longevity even under frequent cycling in HVAC and industrial applications.

Q:What are the main advantages of butterfly valves in HVAC and chilled water systems?

In HVAC and chilled water systems, butterfly valves are preferred for compact size, lightweight, and superior flow regulation. They provide reliable isolation with low pressure loss when fully open and excellent throttling. Their cost-effectiveness and easy installation make them a top choice for system efficiency and temperature control.

Q:What materials are available for the valve body and sealing surface?

The valve body is made of Ductile Iron, with options for Cast Steel and Stainless Steel. The sealing surface features a stainless steel welded disc and an embedded rubber sealing ring (NBR, EPDM, or FPM) that resists loosening.
