Product Q&A
Q:How to select the right check valve?
A:
For water supply and pipelines, use swing or resilient seated valves. Consider flow velocity, pressure (PN10/PN16), and orientation. For slow closure, choose damped valves.
Q:Why are check valves essential in fire protection?
A:
Check valves prevent backflow, protect pumps, maintain pressure, and ensure safety. Resilient seated or double-door check valves offer reliable sealing.
Q:Are check valves suitable for high-frequency changes?
A:
Standard check valves work automatically with flow. Silent or spring-loaded check valves quickly and quietly close in systems with frequent flow changes, reducing water hammer. High-quality designs with effective damping handle demanding conditions efficiently.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves are crucial in HVAC and chilled water systems to prevent reverse flow and protect equipment like pumps and chillers. They feature low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance maintain system efficiency and safeguard components from backflow damage.
Q:What materials are available for the valve body?
A:
We offer customized material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements.
