Product Q&A
Q:How to select the right check valve for water and industrial systems?
A:
For water and industrial pipelines, use swing or resilient seated valves. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For slow closure, select slow-closing or damped valves.
Q:Why are check valves crucial in fire protection and pump systems?
A:
Check valves prevent backflow, protect pumps from reverse rotation, and ensure safety by closing automatically when forward flow stops. Popular for reliable sealing and low pressure drop are resilient seated or double-door check valves.
Q:Are check valves ideal for high-frequency flow changes and automation?
A:
Standard check valves operate automatically with flow direction. For frequent changes, silent or spring-loaded check valves close quickly, reducing water hammer. Quality designs with proper damping handle demanding conditions.
Q:What benefits do check valves offer in HVAC and chilled water systems?
A:
In HVAC and chilled water systems, check valves prevent reverse flow, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss, maintaining efficiency and safeguarding components.
