As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Lug Type Butterfly Valve, engineered specifically for demanding applications in petrochemical and marine systems. Established in 2016 and backed by ISO9001 certification, we understand the critical need for valves that offer superior sealing, robust construction, and easy maintenance in harsh environments. This valve, designed to 150LB ANSI class standards, provides a dependable and cost-effective solution for isolating and regulating flow in your most critical pipelines.

Our Lug Type Butterfly Valve stands out in the market due to its thoughtful design and premium material selection, ensuring longevity and safety in operations.

Rugged Lug Design: The valve features a lugged body with threaded stud holes, allowing it to be installed between two flanges without needing nuts on both sides. This design is particularly advantageous for systems requiring frequent removal for maintenance or inspection, as it supports the pipeline weight and prevents line distortion.
Superior Sealing Performance: Equipped with a resilient seat (available in PTFE, EPDM, NBR, or Viton) that provides bubble-tight shut-off. The seat is securely bonded or locked into the body, ensuring excellent sealing integrity even under fluctuating pressures and temperatures common in petrochemical processes.
Robust Construction: The valve body and disc are manufactured from high-grade materials such as carbon steel (WCB), stainless steel (CF8/CF8M), or ductile iron, offering excellent resistance to corrosion, erosion, and high pressures. The disc is precision-machined and often coated or lined for enhanced durability.
Versatile Actuation Options: To suit diverse operational needs, the valve can be operated via a manual lever, a gear operator for larger sizes, or automated with electric or pneumatic actuators. This flexibility allows for easy integration into both manual and fully automated control systems.
Wide Size and Pressure Range: Available in a broad spectrum of sizes from 2" to 48" (DN50 to DN1200), catering to various pipeline dimensions. The 150LB ANSI rating ensures compatibility with a wide range of system pressure requirements.
Low Torque Operation: The streamlined disc design and low-friction seat material contribute to low operating torque, making manual operation easier and reducing the power requirements for actuators, leading to energy savings.
Bi-Directional Flow Capability: The lug design and seat configuration allow for effective sealing in both flow directions, providing reliable performance regardless of installation orientation.

Benefits for Your Operation:

Enhanced Safety: The robust lug design provides a secure connection, critical for high-pressure petrochemical and marine applications where safety is paramount.
Reduced Maintenance Downtime: Easy installation and removal simplify inspection and maintenance routines, minimizing system downtime and associated costs.
Long Service Life: High-quality materials and precise manufacturing ensure the valve withstands corrosive media, abrasive slurries, and constant cycling, delivering a long lifespan.
Cost Efficiency: Compared to gate or globe valves, butterfly valves offer a more compact, lighter, and often more affordable solution with comparable sealing performance.
System Versatility: Suitable for a wide range of media including water, oil, gas, chemicals, seawater, and slurries in both onshore petrochemical plants and offshore marine vessels.

With an annual export value ranging between US$1 Million and US$1.5 Million and a presence in major global markets including North America, South America, Europe, Asia, Africa, and Oceania, Shanghai Zhibang Valve has proven its capability to deliver reliable industrial valve solutions worldwide.

Frequently Asked Questions (FAQ)

Q: What is the main advantage of a lug type butterfly valve over a wafer type?
A: The primary advantage is the lug design allows for dead-end service. The valve can be bolted into the pipeline using studs and nuts on just one side, supporting the line weight. This makes it suitable for end-of-line applications or where the downstream section needs to be removed without disturbing the upstream piping, which is not possible with a standard wafer valve.
Q: Is this valve suitable for seawater applications in marine systems?
A: Yes, absolutely. When specified with appropriate materials such as stainless steel (316/316L) body and disc, along with a corrosion-resistant seat like EPDM or Viton, this valve performs reliably in seawater and other corrosive marine environments. Optional epoxy or specialized coatings can provide additional protection.
Q: Can this valve be automated?
A: Yes, it is designed for easy automation. The valve stem is compatible with a wide range of electric and pneumatic actuators. We can supply the valve as a complete package with an actuator, positioner, and other controls tailored to your system's needs.
Q: What is the maximum pressure and temperature this valve can handle?
A: As a 150LB ANSI class valve, its pressure rating corresponds to specific temperature thresholds. Typically, with standard resilient seats (like EPDM), it can handle temperatures from -20°C to +150°C at its full 150LB pressure rating. For higher temperatures (up to 200°C), high-performance seats like reinforced PTFE or metal-seated options are available.
Q: What standards does your valve comply with?
A> Our lug type butterfly valves are manufactured in compliance with international standards including API 609, AWWA C504, and ANSI B16.34 for pressure-temperature ratings. The face-to-face dimensions adhere to API 609 or ANSI standards, ensuring interchangeability.
Q: Do you offer custom sizes or materials outside your standard range?
A: As a manufacturer, we have the flexibility to accommodate custom requirements. This includes non-standard sizes, special material grades (like duplex stainless steel, Monel, Hastelloy), extended stems, special coatings, or unique painting specifications. Please consult with our engineering team for feasibility.
Q: What is your lead time for standard orders?
A: For standard configurations in common sizes and materials, our typical lead time is 4-6 weeks. This can vary based on order quantity, specific material availability, and actuator selection. We strive to provide accurate timelines upon receipt of your inquiry.
Q: How do you ensure quality control?
A> Our quality management system is ISO9001 certified. Every valve undergoes rigorous in-process inspections and final testing, which includes hydrostatic shell tests, seat leakage tests (per API 598 or other specified standards), and dimensional checks. Detailed test reports are available upon request.
