Product Q&A
Q:How to select the right check valve for water supply and industrial systems?
A:
For water supply and industrial pipelines, swing or resilient seated check valves are ideal. Consider flow velocity, pressure rating (PN10/PN16), and orientation. Use slow-closing or damped valves to prevent water hammer.
Q:What makes check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow and protect pumps from reverse rotation. They close automatically, ensuring safety and pressure. Resilient or double-door check valves are favored for 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 with flow direction. For frequent flow changes, choose silent or spring-loaded check valves for quick, quiet closure to reduce water hammer. High-quality designs with proper damping handle demanding conditions effectively.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves prevent reverse flow, protecting HVAC and chilled water system equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Their compact design ensures reliable performance, maintaining system efficiency and safeguarding components from backflow.
Q:What are the available nominal diameters?
A:
The available nominal diameters range from DN15 to DN50.
