As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Manual Marine Ball Valve. Engineered for demanding marine and industrial environments, this valve combines robust construction with a full-port design to ensure minimal pressure drop and superior flow rates. Since our establishment in 2016, we have dedicated ourselves to producing fluid control solutions that meet the rigorous standards of global markets, exporting to regions from North America to Oceania. This particular valve is a testament to our expertise, offering dependable on/off control for a wide array of high-flow applications.

Crafted for performance and durability, our ball valve stands out in critical systems. Below are its detailed features and specifications:

Superior Flow Efficiency: The full-port (full-bore) design provides a flow path with an internal diameter equal to the pipeline, drastically reducing flow resistance and pressure loss. This is crucial for systems requiring maximum flow capacity and energy efficiency.
Versatile Thread Compatibility: Available with NPT (National Pipe Tapered) or BSP (British Standard Pipe) threads, including BSPT (tapered) and BSPP (parallel) options. This flexibility ensures easy integration into diverse international piping systems without the need for adapters.
Robust Construction & Materials: The valve body is precision-cast from high-grade brass or corrosion-resistant stainless steel (e.g., SS304, SS316), offering excellent resistance to seawater, chemicals, and harsh weather conditions common in marine settings.
Reliable Sealing: Features PTFE (Teflon) seats and seals, known for their wide temperature tolerance, chemical inertness, and low friction, ensuring a bubble-tight shut-off and long service life with minimal maintenance.
Easy Operation & Maintenance: The quarter-turn manual lever allows for quick and easy open/close operation. Its simple design facilitates straightforward installation, inspection, and seal replacement if necessary.
Wide Application Scope: While ideal for marine applications (bilge systems, ballast, fuel lines, water supply), it is equally suitable for industrial processes, irrigation, chemical handling, and OEM equipment where reliable fluid isolation is needed.

The following table outlines key technical parameters for common models:

Parameter	Specification / Value
Size Range	1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", 2"
Pressure Rating	PN16 (150 PSI @ 20°C) - Standard
Max Working Temperature	-20°C to 180°C (with PTFE seals)
Body Material	Brass CW617N / Stainless Steel 304/316
Seal Material	PTFE (Standard), Viton (Optional)
Handle Material	Stainless Steel or Zinc Alloy
Operation	Manual Lever (Quarter Turn)
Port Type	Full Port

Choosing our Manual Marine Ball Valve provides tangible benefits for your operations:

Enhanced System Performance: Maximizes flow rate, improving the efficiency of pumps and reducing energy consumption.
Reduced Downtime: Durable materials and reliable sealing minimize leaks and failures, leading to lower maintenance costs and increased system uptime.
Global Compliance: Thread options cater to international standards, simplifying procurement and installation for projects worldwide.
Cost-Effective Solution: Offers a balance of high performance, longevity, and competitive pricing, delivering strong value over its lifecycle.

Our commitment to quality is backed by a certified ISO9001 quality management system, ensuring every valve that leaves our Shanghai facility meets consistent performance standards. With an annual export value ranging between US$1 Million and US$1.5 Million, we have built a trusted reputation across diverse markets including North America, South America, Europe, Asia, Africa, and Oceania. We support our clients with flexible shipping options from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing. When you choose Shanghai Zhibang, you are selecting a valve engineered for reliability, supported by a manufacturer with proven global reach and a dedication to customer satisfaction.

Frequently Asked Questions (FAQ)

What is the main advantage of a full-port design over a standard port?
A full-port ball valve has a bore diameter equal to the pipe's inner diameter, creating a straight-through flow path. This design significantly reduces flow restriction and pressure drop compared to standard (reduced) port valves, making it ideal for applications where maintaining high flow velocity and minimizing energy loss are priorities.
Can this valve be used with fluids other than water?
Yes, provided the fluid is compatible with the valve materials (brass/SS304/SS316 and PTFE seals). It is suitable for oils, fuels, air, and many chemicals within the specified temperature and pressure limits. For aggressive chemicals, selecting stainless steel body and verifying seal compatibility (e.g., Viton) is recommended.
How do I choose between NPT and BSP threads?
The choice depends on your existing piping system's standard. NPT is common in North America, while BSP (BSPT-tapered, BSPP-parallel) is prevalent in Europe, Asia, and many Commonwealth countries. Please specify your requirement based on your region's standards or provide the thread specifications of your fittings.
Is this valve suitable for high-pressure applications?
This valve is rated for a working pressure of PN16 or 150 PSI at ambient temperature, which is suitable for many marine and industrial applications. For higher pressure requirements, please inquire about our high-pressure series or confirm the specific pressure rating needed for your application.
What maintenance does this ball valve require?
These valves are designed for low maintenance. Periodic visual inspection for leaks and occasional operation to prevent seizing is advised. The PTFE seats are long-lasting, but if necessary, the valve can be disassembled for seat and seal replacement, extending its service life significantly.
Do you offer different handle options?
The standard configuration includes a manual lever handle. Options such as locking handles, tee handles, or extended handles for hard-to-reach locations may be available upon request. Please contact us with your specific needs.
Are these valves certified for marine use?
While manufactured with marine-grade materials (corrosion-resistant), specific marine certifications (e.g., from classification societies like DNV, ABS, LR) are not standard but can be explored as a custom requirement. Our ISO9001 certification underpins our consistent manufacturing quality.
What is the lead time for an order?
Lead times vary based on order quantity, material choice, and thread specification. For standard sizes and materials, we typically maintain stock for prompt shipment. We provide accurate lead time estimates upon receipt of your detailed inquiry.
