As a professional manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing reliable industrial valves for global markets. Our Cast Iron Pneumatic Butterfly Valve, compliant with the GB/T3036 national standard, represents a robust solution for efficient flow control in demanding applications. Engineered for durability and precise operation, this valve combines the strength of cast iron construction with the convenience and automation capability of pneumatic actuation, offering clients a dependable component for their piping systems.
This valve is designed to handle a wide range of industrial media, including water, air, and certain neutral fluids, within systems operating at a nominal pressure of PN10. The pneumatic actuator enables remote or automated control, significantly enhancing operational efficiency and safety by reducing manual intervention. With our extensive export experience reaching markets across North America, South America, Europe, Asia, Africa, and Oceania, we understand the diverse requirements of international clients and tailor our products to meet those needs.
Key Product Features & Technical Specifications:
- Durable Construction: The valve body is made from high-grade cast iron, providing excellent resistance to corrosion and mechanical stress, ensuring long service life in industrial environments.
- Pneumatic Actuation: Equipped with a pneumatic actuator, allowing for quick opening and closing. Actuator options can be customized (e.g., double-acting or spring-return) based on control system requirements.
- Standard Compliance: Manufactured in accordance with GB/T3036 standards, ensuring dimensional accuracy, performance reliability, and interchangeability within compliant piping systems.
- Sealing Performance: The disc seal is designed for effective shut-off. Sealing ring materials (such as EPDM or NBR) are available upon request to suit specific fluid properties.
- Flanged Connection: Features standard flanged ends (e.g., according to common flange standards like GB, ANSI, or DIN, customizable), facilitating easy and secure installation into existing pipelines.
- Size Versatility: Available in a comprehensive range of nominal diameters from DN100 to DN500, catering to various pipeline scales from smaller distribution lines to larger main conduits.
Detailed Size & Pressure Parameters:
| Nominal Diameter (DN) | Approximate Dimensions (Body) | Pressure Rating (PN) | Typical Actuator Air Pressure Range |
|---|---|---|---|
| DN100 | Compact design for standard pipelines | PN10 | 0.4 - 0.7 MPa (common) |
| DN150 | Mid-size for increased flow capacity | PN10 | 0.4 - 0.7 MPa (common) |
| DN250 | Robust construction for main lines | PN10 | 0.4 - 0.7 MPa (common) |
| DN500 | Large diameter for high-volume systems | PN10 | 0.4 - 0.7 MPa (common) |
Advantages and Client Benefits:
- Operational Efficiency: Pneumatic control enables integration into automated systems, allowing for rapid response, scheduled operations, and reduced labor costs.
- Reliable Performance: Adherence to GB/T3036 ensures predictable performance and compatibility, minimizing installation and maintenance surprises.
- Cost-Effective Solution: Cast iron offers a balance of strength and economy, while the butterfly valve design itself provides a low-profile, space-saving solution compared to other valve types.
- Global Supply Capability: With shipment ports in Shanghai, Guangzhou, Hong Kong, and Beijing, and an annual export value between US$1 Million and US$1.5 Million, we have established a reliable supply chain to deliver products promptly to clients worldwide.
- Customization Flexibility: While offering a standard PN10 rating and DN100-DN500 range, we can discuss specific requirements for actuator types, seal materials, or flange standards to ensure the valve fits your project perfectly.

Frequently Asked Questions (FAQ):
Q1: What fluids is this Cast Iron Pneumatic Butterfly Valve suitable for?
A: It is generally suitable for water, air, and other neutral fluids that are not highly corrosive or abrasive at temperatures and pressures within its design limits. For specific aggressive media, the sealing material selection should be consulted.
Q2: Can the pneumatic actuator be configured for different control signals?
A: Yes. The pneumatic actuator can typically be interfaced with various control systems. Options for solenoid valves, positioners, or different air pressure requirements are available and can be customized based on your automation setup.
Q3: Does the valve come with specific flange standards?
A: The standard product complies with dimensions per GB/T3036. However, flange face details (e.g., raised face, flat face) and drilling patterns can often be aligned with other common standards like ANSI or DIN upon request to match your existing pipeline flanges.
Q4: What is the typical operating temperature range?
A: The cast iron body and standard sealing materials are designed for common industrial temperature ranges. The exact maximum and minimum temperatures depend on the selected seal material; this information is available upon specification.
Q5: Is the valve suitable for frequent cycling or on/off operations?
A: The butterfly valve design, combined with a pneumatic actuator, is well-suited for frequent operation due to its quick actuation and relatively low wear characteristics. The specific actuator type (e.g., spring return for fail-safe action) can be chosen to enhance cycling performance.
Q6: How is the quality control ensured for these valves?
A: Our manufacturing process is governed by an ISO9001 quality management system. This ensures consistent procedures from material inspection, machining, assembly, to final testing, providing reliable product quality.
Q7: What is the delivery lead time for standard sizes?
A: For standard DN sizes within the DN100-DN500 range, we generally maintain stock or short production cycles. Lead times can be confirmed upon inquiry, and our multiple shipment ports facilitate efficient logistics.
Q8: Can I request a different pressure rating, like PN16 or higher?
A: The standard offering is PN10. For higher pressure ratings, the design, materials, and testing would differ. Please contact us to discuss your specific pressure requirement; we can evaluate the feasibility of a customized product.
