Product Q&A
Q:How to choose the right check valve for water and industrial systems?
A:
Use swing or resilient seated valves. Consider flow, pressure (PN10/PN16), and orientation. Slow-closing or damped valves prevent water hammer.
Q:Why are check valves essential in fire protection and pump systems?
A:
They prevent backflow, safeguard pumps from reverse rotation, and close automatically for safety. Resilient or double-door valves ensure 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. For frequent changes, opt for silent or spring-loaded valves for rapid closure and reduced water hammer.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
They prevent reverse flow, protecting equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss.
Q:What materials are used for the valve body and internal components?
A:
The body, cover, disc, and arm are made of CF8 stainless steel. Internal components include stainless steel and rubber.
