Product Q&A
Q:How to select the right check valve for water supply and industrial pipelines?
A:
For water supply, pump outlets, and pipelines, choose swing or resilient-seated check valves. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For slow closure to prevent water hammer, select slow-closing or damped check valves.
Q:What makes check valves essential in fire protection and pump station systems?
A:
Check valves are crucial in fire protection and pump stations by preventing backflow and safeguarding pumps from reverse rotation. They close automatically when forward flow stops, ensuring safety and maintaining pressure. Resilient seated or double-door check valves are favored for their reliable sealing and low pressure drop.
Q:Are check valves suitable for high-frequency flow changes and automated systems?
A:
Standard check valves operate automatically based on flow direction. For frequent flow changes, silent or spring-loaded check valves are ideal as they close swiftly and quietly, minimizing water hammer. High-quality designs with proper damping effectively handle demanding conditions.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves are vital in HVAC and chilled water systems to prevent reverse flow and protect equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliable performance ensure system efficiency and safeguard sensitive components from backflow damage.
