Product Q&A

Q:How to select the right check valve for water supply and industrial systems?

For water supply and industrial pipelines, use 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?

Check valves prevent backflow and safeguard pumps from reverse rotation. Automatic closing ensures safety and pressure. Resilient or double-door check valves offer reliable sealing and low pressure drop.

Q:Are check valves suitable for high-frequency flow changes and automated systems?

Standard check valves operate automatically. For frequent flow changes, use silent or spring-loaded check valves for quick closure, reducing 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?

Check valves prevent reverse flow, protecting 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?

The valve body is made of CF8 stainless steel, and internal components consist of stainless steel plus rubber for reliable sealing.
