ISO9001 Certified Manufacturer
As a dedicated manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing robust and reliable valves for demanding applications. Our Lug Type Handle Butterfly Valve is engineered specifically for marine environments and industrial systems where secure, leak-free performance is critical. Each valve is accompanied by a Mill Test Report, providing verifiable proof of material quality and manufacturing integrity, a commitment to transparency that builds trust with our global partners.
This valve combines a practical lug design for easy installation and removal without disassembling the entire pipeline, with a durable manual handle for precise flow control. It is a cost-effective and versatile solution for seawater cooling, ballast systems, fuel transfer, and various onshore industrial processes.
Key Features & Technical Specifications:
- Lug Design Advantage: The lug body features threaded holes or bolt patterns on both sides, allowing it to be bolted directly between two pipeline flanges. This design isolates the valve from the pipeline stress and facilitates maintenance.
- Durable Construction: The body and disc are typically crafted from materials like carbon steel or stainless steel to withstand corrosive marine atmospheres and abrasive media.
- Sealing Performance: Utilizes high-quality elastomer seats (such as EPDM for freshwater, NBR for oil, or PTFE for high-temperature/chemical resistance) to ensure a tight seal and long service life.
- Manual Handle Operation: The handle provides a direct, mechanical means of operation. It is ergonomically designed for easy 90-degree rotation from fully open to fully closed, with clear visual indication of the valve position.
- Comprehensive Size & Pressure Range: Available in a wide range of sizes to suit various pipeline diameters and pressure requirements.
Below is a reference table for common specifications (specific values may vary based on customer requirements):
| Parameter | Typical Range / Options |
| Nominal Diameter (DN) | DN50, DN80, DN100, DN150, DN200, DN250, DN300, DN400, DN500, DN600 |
| Pressure Rating (PN) | PN10, PN16 |
| Body Material | Carbon Steel WCB, Stainless Steel 304/316, Duplex Steel |
| Disc Material | Stainless Steel 304/316, Aluminum Bronze, Nickel-Plated |
| Seat Material | EPDM, NBR, PTFE, Viton (Customizable) |
| Operation | Manual Lug Handle |
| Face-to-Face Dimension | Standard per ISO 5752 / ASME B16.10 (Available upon request) |
Benefits for Our Clients:
- Simplified Installation & Maintenance: The lug design reduces installation time and cost. It allows for valve replacement without cutting the pipe, minimizing system downtime.
- Enhanced System Safety & Reliability: Robust materials and proven sealing technology ensure reliable performance in harsh marine conditions, protecting valuable assets and operations.
- Cost Efficiency: Compared to other valve types, butterfly valves offer a favorable price-to-performance ratio, especially in large diameters. The manual handle eliminates the need for expensive actuators in many applications.
- Quality Assurance with MTR: The included Mill Test Report details the chemical composition and mechanical properties of the metallic components. This documentation supports quality control procedures and compliance requirements for shipyards, engineering firms, and industrial plants.
- Global Supply Capability: With established export channels through major ports like Shanghai, Guangzhou, Hong Kong, and Beijing, we efficiently serve markets worldwide, including North America, South America, Europe, Asia, Africa, and Oceania.
Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, has grown into a trusted supplier with an annual export value ranging between US$1 Million and US$1.5 Million. Our ISO9001 certification underpins a systematic approach to quality management from raw material sourcing to final inspection. The provision of a Mill Test Report with every valve is not just an added document; it is a testament to our commitment to material traceability and product reliability. This valve represents a blend of practical design, durable construction, and verifiable quality—ideal for projects where performance and documentation are equally important. We encourage you to contact us for detailed specifications, pricing, or to discuss custom requirements for your specific marine or industrial application.
Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a lug-type butterfly valve over a wafer-type?
A: The lug design allows the valve to be bolted independently to each pipeline flange, making it suitable for end-of-line applications or systems where the valve needs to be a structural support point. It also simplifies removal for maintenance. -
Q: Is this valve suitable for seawater applications?
A: Yes, when configured with appropriate materials like stainless steel 316 body/disc and EPDM or PTFE seats, it is well-suited for handling seawater, offering good corrosion resistance. -
Q: What information is included in the Mill Test Report?
A: The MTR typically includes material grade, chemical analysis results, mechanical property test results (like tensile strength, yield strength), heat treatment details, and the manufacturer's certification. It serves as a material quality certificate. -
Q: Can the valve handle other media besides water?
A> Absolutely. By selecting the correct seat material (e.g., NBR for oils, PTFE or Viton for chemicals), the valve can be used for a wide range of media including fuels, mild chemicals, air, and gases. -
Q: Is the manual handle lockable?
A: The standard handle is not inherently lockable, but lockout devices can often be fitted onto the handle for safety purposes in industrial settings. Specific lockable handle options may be available upon request. -
Q: What are the available connection standards?
A: The lug bolt holes are typically designed to match common flange standards such as ANSI/ASME or DIN/JIS/ISO. Please specify your flange standard when inquiring to ensure compatibility. -
Q: Do you offer valves with other types of actuators?
A: While this product focuses on the manual lug handle version, our company can provide butterfly valves equipped with gear operators, pneumatic actuators, or electric actuators based on customer requirements. -
Q: What is your typical lead time for orders?
A: Lead time depends on order quantity, size, and material specifications. For standard configurations, it generally ranges from 30 to 60 days. We provide accurate timelines upon order confirmation.
