As a specialized manufacturer with ISO9001-certified production processes, Shanghai Zhibang Valve Manufacture Co., Ltd. designs and produces robust cast steel marine three-way ball valves engineered for precise flow diversion and control in demanding environments. Established in 2016 and exporting to global markets, we understand the critical need for reliable, durable valves in marine applications and industrial systems. Our L Port and T Port configurations offer versatile solutions for mixing, diverting, or selecting flow paths, ensuring operational efficiency and system integrity.
This valve series is built to withstand the rigorous conditions of marine service, including exposure to seawater, variable pressures, and continuous operation. The cast steel body provides exceptional strength and corrosion resistance, making it a dependable component for shipboard piping, offshore platforms, and coastal industrial facilities. By choosing our valves, you invest in a product backed by stringent quality control and proven performance in markets across North America, South America, Europe, Asia, Africa, and Oceania.
Core Features & Technical Specifications:
- Diversion Versatility: Available in L Port (for changing flow between two ports) and T Port (for mixing or diverting flow between three ports) configurations to suit specific system logic.
- Robust Construction: The main body is manufactured from high-grade cast steel, offering superior mechanical strength and resistance to impact and deformation.
- Enhanced Sealing: Utilizes PTFE (Polytetrafluoroethylene) seats, known for excellent chemical resistance, low friction, and reliable sealing across the specified pressure range.
- Precision Control: The chrome-plated carbon steel ball ensures smooth operation and precise flow modulation with minimal torque requirement.
- Broad Size & Pressure Range: Covers nominal diameters from DN15 to DN100 and pressure ratings from PN16 to PN40, accommodating a wide spectrum of pipeline requirements.
- Operational Flexibility: Standard manual operation via a handwheel or lever. Options for pneumatic or hydraulic actuation are available for automated remote control systems.
- Global Compliance: Manufactured under an ISO9001 quality management system, ensuring consistent production standards and traceability.
Key Advantages & Customer Benefits:
- System Reliability: The durable design minimizes failure risks, reducing maintenance downtime and costly repairs in critical marine and industrial operations.
- Operational Efficiency: Easy switching between flow paths improves process control and can enhance overall system throughput and energy usage.
- Long Service Life: The combination of corrosion-resistant materials and high-quality sealing components extends valve lifespan, even in harsh environments.
- Installation Compatibility: Standard flanged connections facilitate easy integration into existing piping networks. Threaded ends can be provided as an alternative.
- Cost-Effectiveness: By offering a range of sizes and pressures, you can select the optimal valve for your application without over-specifying, managing project budgets effectively.

Frequently Asked Questions (FAQ):
-
Q: What is the main difference between the L Port and T Port configurations?
A: The L Port valve allows flow to be switched between two of the three ports (e.g., from port A to port B, blocking port C). The T Port valve can mix flow from two inlet ports into one outlet, or divert flow from one inlet to two possible outlets. Your choice depends on the required flow pattern in your system. -
Q: Is this valve suitable for freshwater or chemical applications beyond marine use?
A: Absolutely. The cast steel body and PTFE seats offer good corrosion resistance against many fluids. However, for specific aggressive chemicals, we recommend consulting with our engineers to confirm material compatibility or explore optional seat materials. -
Q: Can I get valves with threaded connections instead of flanges?
A: Yes. While flanged connections are standard for easier bolting to pipelines, we can provide valves with threaded (NPT or BSP) ends upon request. Please specify your connection preference when inquiring. -
Q: What is the maximum operating temperature for the standard PTFE seat version?
A: The standard PTFE seats are rated for continuous service within a temperature range of approximately -20°C to +200°C. For higher temperature applications, alternative seat materials can be considered. -
Q: Are these valves available with actuators for automated control?
A: Yes. The manual valve can be fitted with pneumatic or hydraulic actuators for integration into automated control systems. We offer actuator options and can supply the assembled unit. -
Q: How does the PN pressure rating relate to other common pressure standards like PSI or Class?
A: PN is a metric nominal pressure rating. PN16 corresponds roughly to 16 bar. For reference, PN16 ≈ 232 PSI, PN25 ≈ 363 PSI, PN40 ≈ 580 PSI. Our technical datasheets provide detailed conversions. -
Q: What is the typical delivery lead time for standard sizes?
A: For standard DN/PN combinations in L or T port, we generally maintain stock or can produce within a short lead time. Exact delivery times depend on order quantity and specific requirements. We provide estimated schedules upon quotation. -
Q: Does the company provide any warranty or after-sales support?
A> We offer a standard warranty on our valves against manufacturing defects. Additionally, we provide technical documentation and support for installation and maintenance. Our experience serving global markets ensures we understand the importance of reliable after-sales service.
