Product Q&A

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

Resilient seated butterfly valves are ideal for water, HVAC, and industrial pipelines. They offer compact, lightweight design and quick quarter-turn operation. Consider pressure rating, disc and seat materials, and throttling needs for optimal performance.

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

Butterfly valves excel in fire protection and large pipelines due to compact structure, low weight, and quick operation. Their full-flow design reduces pressure drop, while the resilient seat ensures bubble-tight shutoff, ideal for space-limited and main water lines.

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

Yes. Butterfly valves excel in frequent operations with their simple quarter-turn mechanism. When paired with electric or pneumatic actuators, they offer rapid response and precise control. Durable resilient seated designs with strong stems and bearings ensure longevity even during frequent cycling in HVAC and industrial settings.

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

Butterfly valves are favored in HVAC and chilled water systems for their compact, lightweight design and superb flow regulation. They provide reliable isolation, low pressure loss when open, and excellent throttling performance. Their cost-effectiveness and simple installation make them ideal for efficient system management and temperature control.

Q:What is the working principle of this butterfly valve?

Moving the lever rotates the valve shaft and disc through a quarter turn. The disc opens the flow when aligned and restricts as it turns. Closed, it engages the elastomer seat to isolate the pipeline. Locking holds the lever position.
