At Shanghai Zhibang Valve Manufacture Co., Ltd., a professional valve manufacturer established in 2016, we specialize in delivering robust and reliable flow control solutions for demanding industrial applications. Our JIS F7480 standard DN1200 Butterfly Valve with gear operator represents our commitment to engineering excellence, designed to handle large-diameter pipelines with precision and durability. This valve is engineered to meet the rigorous demands of water treatment, power generation, chemical processing, and HVAC systems, providing a cost-effective and efficient shut-off and regulating solution. With an annual export value reflecting our global reach, we ensure every valve is built to perform consistently under pressure, backed by our comprehensive warranty for your peace of mind.

Product Features & Technical Advantages:

Superior Construction & Material: The valve body is crafted from high-grade ductile iron (GGG-40/50), offering exceptional tensile strength, impact resistance, and durability compared to standard gray iron. This material choice ensures longevity and resistance to water hammer effects in large-diameter applications.
Precision Gear Operator: Equipped with a fully enclosed, weatherproof gear operator. This mechanism provides high mechanical advantage, allowing for smooth and effortless opening and closing of the large DN1200 disc, even under high differential pressures. It features a visual position indicator and can be fitted with limit switches or actuators for automation (available upon request).
JIS F7480 Compliance: Manufactured in strict accordance with the Japanese Industrial Standard JIS F7480 for butterfly valves. This guarantees dimensional accuracy, pressure-temperature ratings, and performance metrics that are recognized and trusted in international markets, particularly across Asia and Oceania.
Optimized Disc & Seal Design: The disc is designed with a double eccentric (offset) profile. This design reduces operating torque and minimizes wear on the seat by ensuring the disc lifts away from the seat immediately upon opening. The seat is available in various elastomers (EPDM for water, NBR for oils, PTFE for chemicals) to suit different media.
Robust Stem & Bearing System: Features a stainless steel stem (SS304/SS316) that is fully isolated from the line media, preventing corrosion. Self-lubricating bushings support the stem, ensuring smooth rotation and long-term, maintenance-free operation.
Versatile Connection & Coating: Available in wafer or lug body styles to suit different piping installation requirements. The external surface receives a high-quality epoxy powder coating, providing excellent corrosion resistance for use in harsh environments.

Benefits for Your Project:

Reliable Performance in Large Lines: Specifically engineered for DN1200, this valve ensures secure and bubble-tight shut-off in major water mains, intake lines, and effluent discharge systems, reducing the risk of costly leaks or process interruptions.
Reduced Lifecycle Cost: The combination of ductile iron construction, corrosion-resistant coating, and low-maintenance gear drive results in a valve with an extended service life and minimal operational expenses.
Ease of Installation & Operation: The compact, lightweight design (compared to gate valves of similar size) and wafer/lug connections simplify installation. The gearbox allows for manual operation without excessive force, enhancing site safety.
Global Market Compatibility: Adherence to JIS F7480 makes this valve a suitable choice for projects in Southeast Asia, Eastern Asia, Oceania, and other regions where this standard is specified or accepted, facilitating easier project approval.
Customization Flexibility: We offer options for seat materials, end connections, actuation (electric, pneumatic, hydraulic), and painting standards to meet specific project specifications or environmental conditions.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of using a gear operator on a DN1200 butterfly valve?
A: A gear operator provides a significant mechanical advantage, drastically reducing the force required to open or close the valve. For a large 1200mm diameter disc, manual operation via a handwheel alone would be extremely difficult. The gearbox makes it manageable for a single operator, improves control for throttling, and enhances safety.
Q: Can this JIS F7480 valve be used in systems designed to other standards like ANSI or DIN?
A: While designed to JIS F7480, the pressure ratings (PN10/16) are comparable to common classes. The face-to-face dimensions may differ slightly from ANSI or DIN standards. It is crucial to verify the specific dimensional and pressure-temperature requirements of your project. We can advise on compatibility or offer valves built to other standards upon request.
Q: What media is this valve suitable for?
A: With the appropriate seat selection, it is suitable for a wide range of media. EPDM seats are standard for potable water, cooling water, and air. NBR is used for oils and fuels. PTFE or similar seats are recommended for aggressive chemicals, acids, or alkalis. Please consult with us for your specific media.
Q: Is the valve suitable for buried or submerged service?
A: The standard epoxy coating provides good corrosion resistance for above-ground installations. For direct burial or submerged applications, a more robust coating like Fusion Bonded Epoxy (FBE) or an additional cathodic protection kit would be recommended and can be supplied as an option.
Q: What does the warranty cover and for how long?
A: Our standard warranty covers defects in materials and workmanship under normal use and service for a specified period from the date of shipment (typically 12-18 months). It does not cover damage from misuse, improper installation, or wear and tear of consumable parts like seats. Exact warranty terms are provided with the commercial contract.
Q: Can this valve be automated?
A: Yes, absolutely. The gear operator is designed to be easily fitted with various electric, pneumatic, or hydraulic actuators. We can supply the valve as a complete actuated package, including mounting brackets, controls, and necessary accessories, tailored to your automation needs.
Q: What testing is performed before shipment?
A: Each valve undergoes rigorous testing, which typically includes a hydrostatic shell test (at 1.5x rated pressure) and a seat leakage test (per API 598 or equivalent standard) to ensure zero leakage. Test certificates are available as part of the documentation package.
Q: What is the lead time for a DN1200 valve?
A: Lead time depends on order quantity, customization requirements, and current production schedule. For standard configurations, we generally aim for a competitive lead time. We recommend contacting our sales team with your project timeline for an accurate delivery estimate.
