Product Q&A
Q:How to select the right check valve for water supply and industrial systems?
A:
For water supply, pump outlets, and pipelines, swing or resilient seated check valves are recommended. Consider flow velocity, pressure rating (PN10/PN16), and orientation. For slow closure, choose damped check valves.
Q:What makes check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow and protect pumps from reverse rotation in fire protection and pump stations. They close automatically, ensuring safety and pressure maintenance. Resilient seated or double-door check valves are popular 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 based on flow. For frequent changes, silent or spring-loaded check valves close quickly and quietly, reducing 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 in HVAC systems, protecting pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Their compact and reliable design maintains efficiency, safeguarding components from backflow damage.
Q:Can the valve body material be customized?
A:
Yes, we offer customized material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements.
