Product Q&A
Q:How to select the right check valve for water supply and industrial systems?
A:
For water supply and industrial pipelines, opt for swing or resilient seated check valves. Consider flow velocity, pressure rating (PN10/PN16), and orientation. Slow-closing or damped valves prevent water hammer.
Q:What makes check valves essential in fire protection and pump systems?
A:
Check valves prevent backflow and protect pumps from reverse rotation. Automatic closure ensures safety and pressure. Resilient or double-door check valves provide reliable sealing and low pressure drop.
Q:Are check valves suitable for high-frequency flow changes and automated systems?
A:
Standard check valves work automatically. For frequent flow changes, use silent or spring-loaded check valves for quick closure, minimizing water hammer. High-quality designs with damping handle tough conditions.
Q:What are the main advantages of check valves in HVAC and chilled water systems?
A:
Check valves prevent reverse flow and safeguard HVAC and chilled water equipment like pumps and chillers. They offer low cracking pressure, tight shutoff, and minimal pressure loss. Their compact design ensures reliability, maintaining efficiency and shielding components from backflow damage.
Q:What materials are used for the valve body and internal components?
A:
The valve body, cover, disc, and rocker arm are made of CF8 stainless steel. Internal components include stainless steel and rubber, with SS304 and graphite gaskets for reliable sealing.
