Product Q&A

Q:How does the valve operate without external power?

It uses pipeline water pressure in the diaphragm chamber. Releasing upper chamber pressure lets inlet pressure lift the assembly, while water in the upper chamber pushes the diaphragm down to adjust flow.

Q:What materials are available for the valve body?

The valve body is available in Ductile Iron (GGG50), Cast Steel, and Stainless Steel (SS304/SS316) to meet specific project requirements.

Q:Is customization available for this product?

Yes, we support OEM/ODM customization, custom flange standards, and provide technical drawing requests in PDF or CAD formats.

Q:Which industries can this valve be applied to?

It is widely used in HVAC chilled water systems, industrial fire pump stations, municipal drainage networks, and high-rise building water supply systems.

Q:What certifications does the product hold?

The product is certified with GS, CE, and ISO9001 standards, ensuring quality and safety for international markets.
