As a professional manufacturer with a strong export presence, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our API 609 Electric Butterfly Valve. Engineered for demanding industrial applications, this valve combines robust construction with precise automated control. The 316L stainless steel body ensures superior corrosion resistance, while the PTFE lining provides excellent chemical compatibility, making it an ideal solution for handling aggressive media. Our commitment to quality, backed by ISO9001 certification, ensures you receive a reliable and durable valve designed for long-term performance and minimal maintenance.
This valve is specifically built to meet the rigorous requirements of industries where fluid control integrity is paramount. The electric actuator offers convenient remote operation and integration into process control systems.
- Superior Material Construction: The valve body is crafted from 316L stainless steel, offering enhanced resistance to pitting and corrosion in chloride environments compared to standard 316 grades. This material choice is critical for applications in chemical processing, marine, and offshore industries.
- High-Performance PTFE Lining: The interior is lined with PTFE (Polytetrafluoroethylene), a fluoropolymer known for its exceptional chemical inertness, low friction, and wide temperature range. This lining creates a smooth, non-stick surface that prevents contamination and ensures a tight seal against the disc.
-
Precise Electric Actuation: The integrated 380V 3-phase electric actuator provides reliable and accurate positioning control. Features typically include:
- Local and remote control capability.
- Position feedback signals (e.g., 4-20mA).
- Manual override for emergency operation.
- Adjustable opening/closing speeds.
- Compliance with API 609 Standard: Designed and manufactured in accordance with API 609, the standard for "Butterfly Valves: Double Flanged, Lug- and Wafer-Type." This ensures the valve meets recognized industry specifications for dimensions, pressure-temperature ratings, materials, and testing.
- Robust Pressure Rating: Rated for Class 300 (PN50), this valve is suitable for a wide range of moderate to high-pressure applications, providing a reliable shut-off in critical piping systems.
Key technical specifications for the DN350 size are summarized below:
| Parameter | Specification |
| Valve Size (Nominal Diameter) | DN350 (14") |
| Pressure Class | ASME Class 300 |
| Body Material | 316L Stainless Steel |
| Disc Material | 316L SS with PTFE Coating / Encapsulation |
| Seat / Lining | PTFE (Full Lining) |
| Design Standard | API 609 |
| Actuator Power Supply | 380V AC, 3-Phase, 50/60Hz |
| Connection | Wafer or Lug Style (Configurable) |
| Operating Temperature Range (Lining) | Approx. -20°C to 200°C (-4°F to 392°F) |
The primary advantages of choosing this valve translate directly into operational benefits for your facility:
- Enhanced System Reliability: The combination of 316L SS and PTFE provides long service life even with corrosive fluids, reducing unplanned downtime and replacement costs.
- Improved Process Control: Electric actuation allows for seamless integration with PLCs and SCADA systems, enabling precise flow modulation and automated process sequences.
- Low Maintenance Design: The PTFE lining resists scaling and buildup, and the robust actuator is designed for minimal maintenance intervals.
- Broad Application Suitability: Ideal for industries such as chemical processing, pharmaceuticals, water & wastewater treatment, food & beverage (with appropriate certifications), and power generation.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a PTFE-lined butterfly valve?
A: PTFE lining offers exceptional chemical resistance against a vast array of aggressive acids, bases, and solvents. It also provides a non-stick, smooth surface that minimizes pressure drop, prevents media adhesion, and ensures a reliable bubble-tight seal, making it perfect for corrosive or high-purity applications.
Q2: Can this valve be used for both on/off and throttling control?
A: Yes. While butterfly valves are excellent for on/off service, when paired with a modulating electric actuator like the one supplied, they can perform precise flow control (throttling) within their designed flow characteristics. The actuator's positioning capability allows for stable intermediate positions.
Q3: Is the 380V 3-phase actuator suitable for my region's power supply?
A: The 380V 3-phase, 50/60Hz specification is a common industrial standard globally. However, actuator voltage and phase can often be customized. Please specify your local power requirements (e.g., 460V, 220V, single-phase) during inquiry, and we can check availability or offer a suitable alternative.
Q4: What does "API 609" compliance mean for this valve?
A: API 609 is an American Petroleum Institute standard that defines requirements for double flanged, lug-, and wafer-type butterfly valves. Compliance ensures the valve meets specific criteria for design, materials, dimensions, pressure-temperature ratings, and testing, providing assurance of quality and interoperability in piping systems.
Q5: What is the difference between wafer and lug body styles, and which one do you supply?
A: A wafer-style valve is installed between two pipe flanges using long bolts. A lug-style valve has threaded inserts (lugs) allowing it to be bolted directly to each flange, which can support the valve weight in dead-end service. This valve is typically available in both configurations; the standard offering can be confirmed upon order.
Q6: What is the typical lead time for an order of this DN350 valve?
A: Lead times vary based on order quantity and current production schedule. For standard configurations, we often maintain some inventory or have shorter production cycles. Please contact our sales team with your required quantity for an accurate delivery estimate.
Q7: Are spare parts like PTFE seats or actuator gears available?
A: Yes. As the manufacturer, we provide comprehensive after-sales support, including a supply of genuine spare parts such as PTFE linings/seats, seals, discs, and actuator components to ensure the long-term operability of your valves.
Q8: Can this valve handle abrasive slurries?
A: While PTFE has good chemical resistance, it can be susceptible to abrasion from solid particles. For mildly abrasive services, it may perform adequately, but for highly abrasive slurries, alternative lining materials (like hard-faced metals) or different valve types (e.g., knife gate valves) might be more suitable. Please share your specific media details for a recommendation.
