As a professional manufacturer specializing in high-performance industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Three-Way CB/T3191 Electric Marine Ball Valve. Engineered with 316 stainless steel and integrated with the Modbus RTU protocol, this valve is designed to deliver reliable, automated flow control in demanding marine and industrial applications. Since our establishment in 2016, we have focused on producing durable and technologically advanced valves, exporting to markets worldwide, including North America, Southeast Asia, Europe, and beyond. This product exemplifies our commitment to quality, innovation, and meeting the specific needs of global clients.
This valve combines robust construction with smart automation, offering a solution for complex piping systems requiring diversion, mixing, or distribution of fluids.
- Premium Material Construction: The valve body and critical components are manufactured from 316 stainless steel. This material offers superior resistance to corrosion, pitting, and crevice corrosion, especially in chloride-rich environments like seawater, making it ideal for marine applications and harsh industrial settings.
- Smart Electric Actuation & Control: The valve features a precision electric actuator enabling remote and automated operation. Its integration with the widely adopted Modbus RTU protocol allows for seamless communication within industrial control systems (ICS), SCADA networks, and PLCs, facilitating centralized monitoring and control.
- Three-Way Configuration for Versatile Flow Management: The three-way (L-port or T-port) design provides multiple flow path options, such as diverting flow from one inlet to two outlets, mixing flows from two inlets into one outlet, or selecting between different supply lines. This versatility is crucial for complex system designs.
- Standardized Connection for Easy Integration: The valve complies with the CB/T3191 standard, ensuring compatibility with piping systems commonly used in marine and specific industrial sectors, simplifying installation and replacement processes.
- Durability and Long Service Life: Designed for continuous operation under pressure and in corrosive media, the valve ensures long-term reliability, reducing maintenance frequency and operational downtime.

Frequently Asked Questions (FAQ):
-
What is the main advantage of using 316 stainless steel for this marine valve?
316 stainless steel contains molybdenum, which significantly enhances its corrosion resistance, particularly against chlorides (like seawater), acids, and other corrosive agents common in marine and industrial environments. This ensures longer service life and reduced maintenance compared to standard stainless steels like 304.
-
How does the Modbus RTU protocol integration benefit my control system?
Modbus RTU is a widely used serial communication protocol in industrial automation. Integrating it allows the valve actuator to communicate directly with your PLC, DCS, or SCADA system. You can remotely open/close the valve, monitor its status (open/closed/travel), receive fault alerts, and integrate it into automated sequences without additional hard wiring for signals.
-
Can this valve be used for applications other than marine?
Absolutely. While designed for marine toughness, its 316 SS material and three-way electric design make it suitable for many industrial applications, including chemical processing, pharmaceutical water systems, food and beverage (with proper cleaning), and general industrial fluid control where corrosion resistance and automated diversion/mixing are needed.
-
What does "Three-Way" configuration mean, and what flow patterns are possible?
A three-way ball valve has three ports. Depending on the ball's port design (L-port or T-port), it can perform different functions: diverting flow from one common inlet to two selectable outlets; mixing flow from two inlets into one common outlet; or selecting one active inlet from two sources. The specific pattern depends on the ordered model.
-
Is the electric actuator suitable for modulating (throttling) control, or only on/off?
Our valves can be supplied with either on/off (open/close) electric actuators or modulating actuators that allow for proportional control of flow. This depends on your project requirements and the specific actuator model selected. Please specify your control needs when inquiring.
-
What are the typical voltage options for the electric actuator?
Common power supply options include 24V DC (for low-power safety), 110V AC, and 220V AC. The available options depend on the actuator model and your regional electrical standards. We can provide actuators matching your local power specifications.
-
Does compliance with CB/T3191 standard ensure compatibility with international piping?
CB/T3191 is a Chinese national standard for marine valves, widely recognized and compatible with many international marine and industrial piping systems, especially in regions where this standard is adopted. It ensures specific dimensional and performance criteria. For projects requiring other standards (like ANSI, DIN, JIS), please inquire as custom manufacturing may be available.
-
What is the lead time and shipping process for orders?
Lead times vary based on order quantity and specific configurations. As an experienced exporter with annual export value between US$1-1.5 million, we ship from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing. We manage logistics efficiently to markets across North America, Europe, Asia, Africa, and Oceania, ensuring reliable delivery.
