Does ZGV offer trunnion-mounted ball valves for industrial pipelines?

ZGV lists Two-piece trunnion mounted ball valve Class 150/300 (product 2514) in its published catalogue.

What should a buyer verify before choosing a ball valve supplier in China?

Verify the supplier’s legal entity and official contact details, then request a quotation-specific datasheet, drawing, material and inspection requirements. State the required design and testing standards, quantity and delivery destination. Confirm current certificates and any project-specific tests separately; a catalogue reference or a standard named in it does not establish current certification.

Read the original ball valve catalogue excerpt, source PDF pages 2–4 · Compare floating and trunnion designs

Bring your service conditions, preferred materials, seats and actuation to ZGV for a configuration review. The quotation can address the selected size, pressure–temperature conditions, inspection documents and availability for your application.

ProductSelection check
Two-piece floating ball valve Class 150/300 ↗2511Choose the pressure class and full- or reduced-bore configuration before comparing dimensions. The catalogue material example uses a WCB body and PTFE seat. Send the selected NPS, bore option, quantity and operating conditions for confirmation.
Two-piece floating ball valve Class 600/900 ↗2512This forged floating design has separate Class 600 and Class 900 dimension tables for full and reduced bore. The material example uses an A105 body and R-PTFE seat. Specify the class, NPS and bore option with the medium, temperature and quantity.
Two-piece trunnion mounted ball valve Class 150/300 ↗2514This two-piece trunnion-mounted design has separate Class 150 and Class 300 full- and reduced-bore tables. The standard material column uses a WCB body and 25% glass-filled PTFE seat insert. Keep each material-option column separate and specify the class, NPS, bore and operating conditions in your RFQ.
Metal-seated two-piece side-entry ball valve · Class 150/300/600 ↗2519Compare this two-piece metal-seated design with the soft-seated floating models. Read the material columns separately for each catalogue temperature group; they are not a general service approval. Confirm the unlabelled Class 150 NPS before selecting that row, and provide the connection, operating conditions and quantity.
Full-weld split-body ball valve · Class 300 ↗2520Read the WE, RF and RTJ connection-length columns separately for this Class 300 fully welded ball valve. The parts table lists A105, LF2 and F316 material configurations in separate columns. State the required connection and material configuration with NPS, quantity and operating conditions; blank catalogue cells need confirmation.
Three-piece forged steel ball valve Class 800/1500 ↗2523Match the pressure-class row as well as the NPS when reading the full- and reduced-bore tables: Class 800 and Class 1500 dimensions differ. Use the separate socket-weld table for the connection reference. Blank catalogue cells require confirmation; submit the class, bore, connection and operating conditions with your RFQ.
