Product Q&A

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

For water supply, HVAC, and industrial pipelines, resilient seated butterfly valves are recommended. They offer compact design, lightweight, and quick 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?

Butterfly valves are ideal for fire protection and large pipelines due to compact structure, low weight, and fast operation. Their full-flow design provides minimal pressure drop, and the resilient seat ensures bubble-tight shutoff, perfect for space-limited and main water supply lines.

Q:Are butterfly valves suitable for frequent operation?

Yes. Butterfly valves excel in high-frequency operation and automation due to their simple quarter-turn mechanism. With electric or pneumatic actuators, they ensure fast response and precise control. High-quality resilient seated designs with robust stems and bearings offer durability even in frequent cycling for HVAC and industrial applications.

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 excellent flow regulation. They provide reliable isolation with low pressure loss when fully open and good throttling. Their cost-effectiveness and easy installation make them ideal for maintaining system efficiency and temperature control.

Q:What is the nominal pressure rating?

The nominal pressure rating is PN10, suitable for low-pressure applications (Pn<1.6mpa).
