Product Q&A
Q:How to select the right check valve for water supply and industrial pipelines?
A:
For water systems, use swing or resilient seated valves. Consider flow velocity, pressure (PN10/PN16), and orientation. For slow closure, select damped valves.
Q:What makes check valves essential in fire protection and pump stations?
A:
Check valves prevent backflow and protect pumps, closing automatically for safety, maintaining pressure. Resilient seated or double-door valves ensure reliable sealing.
Q:Are check valves suitable for high-frequency flow changes and automated systems?
A:
Standard check valves auto-operate with flow. For frequent changes, silent or spring-loaded valves close quickly, reducing hammer. High-quality designs with damping meet demanding conditions.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves prevent reverse flow and protect HVAC and chilled water systems, including pumps and chillers. With low cracking pressure, tight shutoff, and minimal pressure loss, their compact design ensures system efficiency and safeguards against backflow damage.
