Frequently Asked Questions (FAQ)

Q: How does a swing check valve function in a pipeline?

A swing check valve contains a swinging disc hinged at the top. Forward fluid flow pushes the disc open, allowing media to pass freely. When the flow stops or reverses, gravity and downstream pressure push the disc back onto its seat, preventing backflow and protecting pumping equipment.

Q: What applications are suitable for this swing check valve?

It is ideally designed for municipal water networks, pump stations, industrial water systems, and fluid control pipelines requiring reliable, maintenance-free backflow prevention.

Q: Which international quality certifications do your valves comply with?

Our products are manufactured under Lloyd's Register (LR) ISO9001:2015 quality management system certification (ISO 9001 – 00033059) and comply with CE/PED European Conformity (Certificate No: 0343/PED/SHA/BJG00001668/A).

Q: What is the available size range and pressure rating for your valve lineup?

Our valve portfolio covers pressure ratings from 0.5 to 6.4 MPa and nominal sizes ranging from DN15 to DN3000 to meet diverse engineering project requirements.

Q: What key materials ensure the sealing integrity and durability of the valve?

The valve body and bonnet are constructed from high-grade Cast Iron (BS1452 Cr.180), complemented by a cast bronze disc ring (BS1400 LG2), brass stem/pins (BS2874 CZ12), and graphite body gaskets to ensure tight sealing and corrosion resistance.

Q: Can you support OEM manufacturing and international project delivery?
