Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 with an annual export value of US$1–1.5 million, proudly presents our Full Bore CB/T3191-92 High Pressure Ball Valve 1500LB. As a professional manufacturer based in Shanghai, China, we have been supplying reliable valve solutions to markets across North America, South America, Europe, Southeast Asia, and the Middle East. This ball valve is engineered to meet the demanding requirements of high-pressure systems, offering full bore flow capacity to minimize pressure drop and ensure efficient media transport. Built to the Chinese standard CB/T3191-92 and rated for Class 1500, it is an ideal choice for marine, oil & gas, and industrial applications where safety and durability are paramount.
Our manufacturing facility is ISO9001:2015 certified, ensuring that every valve undergoes strict quality control from raw material inspection to final testing. The Full Bore design allows for unrestricted flow, reducing erosion and turbulence, while the 1500LB pressure rating guarantees robust performance under extreme conditions. Whether you need a manual, gear-operated, or actuated version, we offer customization options to suit your specific pipeline requirements.
Key Features & Technical Specifications
- Full Bore Design: Port diameter equal to pipeline inner diameter, reducing friction loss and increasing flow efficiency.
- High Pressure Rating: 1500LB (Class 1500) – suitable for systems up to approximately 250 bar (depending on temperature and material).
- CB/T3191-92 Compliance: Manufactured according to Chinese marine standard, widely accepted in shipbuilding and offshore industries.
- Material Options: Available in carbon steel (WCB, WCC), stainless steel (CF8, CF8M, 316L), and duplex alloys for corrosive media.
- Sealing Performance: PTFE or reinforced PTFE seats for bubble-tight shut-off; optional metal seats for high-temperature applications.
- Fire-Safe Design: Optional API 607 fire-safe testing to ensure integrity in case of fire.
- Anti-Static Device: Prevents electrostatic charge buildup, enhancing safety in flammable environments.
- Blowout-Proof Stem: Stem design prevents accidental ejection under pressure, meeting ASME B16.34 requirements.

Frequently Asked Questions (FAQ)
- What does “Full Bore” mean? Full Bore (also called full port) means the ball has a bore diameter equal to the pipe inner diameter, providing unrestricted flow and minimal pressure drop.
- What is the maximum working pressure for this 1500LB valve? The 1500LB rating corresponds to a maximum allowable working pressure that varies with temperature and material. Typically, at ambient temperature for carbon steel, it is about 250 bar (3625 psi). Please consult our technical data sheet for exact values.
- Can this valve be used for seawater applications? Yes, with proper material selection. We recommend stainless steel (CF8M) or duplex stainless steel for corrosive seawater environments. Contact us for material recommendations.
- Is the valve fire-safe certified? Fire-safe design is available as an option to API 607. Please specify your requirement when ordering.
- What are the available end connections? Standard connections are flanged (RF or RTJ) and butt weld. Other connections like socket weld or threaded are available upon request.
- Do you provide actuation (pneumatic/electric)? Yes, we offer manual gearbox, pneumatic actuator, and electric actuator options. We can also supply complete valve-actuator assemblies.
- What is the typical lead time? For standard sizes and materials, lead time is 15–30 days. Custom or large orders may require 30–45 days.
- How do you ensure quality? Each valve undergoes hydrostatic shell test, seat leakage test, and visual inspection per ISO9001 procedures. Test reports are provided with shipment.
