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 shine in fire protection and large pipelines due to compactness, low weight, and swift operation. Their full-flow design reduces pressure drop, and resilient seats ensure reliable shutoff, ideal for tight spaces and main water lines.

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

Yes. Butterfly valves suit high-frequency operation and automation via their quarter-turn mechanism. With electric or pneumatic actuators, they enable fast response and precise control. Durable resilient seated designs ensure longevity under frequent cycling in HVAC and industrial uses.

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

Butterfly valves are ideal in HVAC and chilled water systems for compact size, lightweight, and superior flow regulation. They offer reliable isolation with low pressure loss when fully open and excellent throttling. Cost-effective and easy to install, they enhance system efficiency and temperature control.

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

The valve body is made of Ductile Iron. We offer customized material options including Cast Steel and Stainless Steel. Seal surfaces use soft sealing materials like NBR, EPDM, or FPM depending on temperature requirements.
