Product Q&A
Q:How to select the right check valve for water and industrial pipelines?
A:
For water/pipelines, swing or resilient seated check valves are suggested. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For slow closure, choose slow-closing or damped valves to avoid water hammer.
Q:Why are check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow, protect pumps from reverse rotation, and close automatically when forward flow stops. They ensure safety and pressure maintenance. Resilient seated or double-door check valves offer reliable sealing and low pressure drop.
Q:Are check valves suitable for frequent flow changes and automation?
A:
Standard check valves operate automatically with flow. For frequent flow changes, silent or spring-loaded check valves close swiftly and quietly to reduce water hammer. High-quality designs with proper damping handle demanding conditions.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves are essential in HVAC and chilled water systems to prevent reverse flow and protect pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss when open. Their compact design and reliability maintain system efficiency and safeguard components from backflow damage.
Q:What is the working temperature range of this valve?
A:
The working temperature range is up to 80 degrees Celsius.
