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 highly recommended. They offer compact design, lightweight construction, and quick quarter-turn operation. When selecting, consider the pressure rating (PN10/PN16), disc and seat materials, and whether throttling control is required to ensure optimal performance and long service life.

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

Butterfly valves are widely used in fire protection and large-diameter pipelines due to their compact structure, low weight, and fast open/close operation. Their full-flow design when open provides minimal pressure drop, while the resilient seat ensures reliable bubble-tight shutoff, making them an excellent choice for space-limited installations and main water supply lines.

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

Yes. Butterfly valves are well-suited for high-frequency operation and automation thanks to their simple quarter-turn mechanism. When equipped with electric or pneumatic actuators, they deliver fast response and precise control. High-quality resilient seated designs with robust stems and bearings ensure durability even under frequent cycling in HVAC and industrial applications.

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

Butterfly valves are popular in HVAC and chilled water systems because of their compact size, lightweight design, and excellent flow regulation capability. They provide reliable isolation with low pressure loss when fully open and good throttling performance. Their cost-effectiveness and easy installation make them a preferred solution for maintaining system efficiency and temperature control.
