Certification ISO9001 Quality Management System

As a leading manufacturer with a strong export presence across global markets, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our Automated Trunnion Ball Valve, engineered specifically for the demanding environments of water treatment distribution networks. Designed for reliability and long-term performance, this valve offers superior sealing and automated control, ensuring efficient and safe fluid management in critical infrastructure. Our commitment to quality, backed by our ISO9001 certification and years of manufacturing expertise since 2016, ensures that every valve meets the highest standards for durability and functionality.

This valve is built to comply with API 6D specifications, making it a trusted choice for pipeline applications where safety and performance are non-negotiable. Its automated operation reduces manual intervention, enhances process control, and minimizes the risk of human error, which is crucial for maintaining consistent water quality and distribution pressure.

Key Features and Technical Advantages:

Trunnion-Mounted Design: The ball is fixed on a trunnion, providing exceptional stability and reducing operating torque. This design is particularly effective for high-pressure applications common in main distribution lines, preventing seat deformation and ensuring reliable shut-off even after prolonged use.
Automated Actuation: Available with pneumatic (double-acting or spring-return) or electric actuators, allowing for seamless integration into SCADA systems or remote control setups. This enables automated opening/closing, flow modulation, and emergency shutdown procedures.
Robust Construction for Water Treatment: Materials are selected to resist corrosion from treated water, chemicals, and varying pH levels. Common body materials include carbon steel with epoxy coating or stainless steel, while seat materials like PTFE offer excellent sealing and chemical resistance.
Fire-Safe Design Option: Certain models can be configured with fire-safe features, where secondary metal seats provide a seal in case the primary polymer seats are compromised during a fire event, a critical safety consideration for some installations.
Low Maintenance & Extended Service Life: The trunnion design and quality sealing components minimize wear. Self-lubricating stem bearings and blowout-proof stem design contribute to a long service life with minimal maintenance requirements.
Full Port or Reduced Port: Customers can choose between full port (full bore) designs for minimal pressure drop and pigging capability, or standard/reduced port designs for cost-effective solutions where full flow is not critical.

Benefits for Your Water Treatment Network:

Enhanced System Reliability: Automated control ensures precise operation, reducing the risk of pressure surges or flow inconsistencies that can affect water quality.
Operational Cost Savings: Remote automation reduces the need for on-site personnel for routine valve operations, lowering labor costs and improving safety.
Reduced Water Loss: Superior sealing performance minimizes leakage, conserving valuable treated water and maintaining network efficiency.
Scalability and Flexibility: With a wide size and pressure range, these valves can be used from inlet/outlet lines to main distribution headers, offering a scalable solution for growing networks.
Global Compliance: API 6D compliance ensures the valve meets internationally recognized standards for pipeline valves, facilitating project approvals and ensuring compatibility with other system components.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of a trunnion-mounted ball valve over a floating ball valve for water treatment?
A: The trunnion-mounted design provides much higher stability, especially in larger sizes and higher pressure classes. It significantly reduces operating torque, extends seat life, and is better suited for the main pipeline applications in distribution networks where reliability is critical.
Q: Can this valve be used for both on/off and throttling (flow control) service?
A: While primarily designed for reliable on/off service, when paired with a modulating electric actuator or a pneumatic actuator with positioner, it can be used for flow control or throttling applications within its design limits.
Q: What types of actuators do you offer, and how do I choose?
A: We offer both pneumatic and electric actuators. Pneumatic actuators are preferred for their fast action, explosion-proof nature, and suitability where plant air is available. Electric actuators are chosen for precise control, easier integration with digital control systems, and locations without compressed air. The choice depends on your site's available utilities and control requirements.
Q: Is the valve suitable for potable water applications?
A: Yes. We can supply valves with body coatings (like epoxy) and seat/seal materials that comply with relevant potable water standards (e.g., WRAS, KTW, NSF/ANSI 61). Please specify this requirement when inquiring.
Q: What is the typical delivery lead time for a custom-sized valve with an actuator?
A: Lead times vary based on size, material, and actuator specifications. Standard configurations typically have shorter lead times. We provide accurate delivery schedules upon receipt of your detailed specifications.
Q: Do you provide support for actuator mounting, wiring, and commissioning?
A: We supply the valve and actuator as a pre-assembled and tested unit, ready for installation. We provide mounting brackets, necessary linkages, and detailed installation manuals. Technical support for integration into your control system is available.
Q: How does API 6D compliance benefit my project?
A: API 6D is a globally recognized standard for pipeline valves. Compliance ensures the valve is designed, manufactured, and tested to rigorous requirements for pressure containment, operation, and fire safety (if applicable), which is often mandated by engineering specifications and reduces technical risk for your project.
Q: Are spare parts readily available?
A: Yes. As the manufacturer, we maintain an inventory of critical spare parts like seats, seals, and stem packs. We recommend purchasing a maintenance kit with your valve order for future needs.
