Product Q&A
Q:How to select the right check valve for water supply and industrial pipeline systems?
A:
For water supply/pipelines, choose swing or resilient seated check valves. Consider flow velocity, pressure rating (PN10/PN16), and installation orientation. For slow closure, opt for slow-closing or damped valves to prevent water hammer.
Q:What makes check valves essential in fire protection and pump station systems?
A:
Check valves prevent backflow, protect pumps from reverse rotation, and close automatically when forward flow stops, ensuring safety and pressure maintenance. Resilient seated/double-door check valves offer 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, silent or spring-loaded check valves close swiftly and quietly, reducing water hammer. High-quality designs with 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 for this valve?
A:
The working temperature range is up to 80 degrees Celsius.
