As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve has been dedicated to producing high-quality industrial valves since 2016. Our Cast Iron Lever Operated Butterfly Valve, compliant with the GB/T3036 standard, is engineered for reliable on/off and throttling service in a wide range of applications. Designed for durability and ease of operation, this valve offers an excellent balance of performance and cost-effectiveness, making it a trusted choice for fluid control systems globally. With an annual export value reaching up to US$1.5 million, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania, ensuring our products meet diverse international requirements.

This robust butterfly valve is constructed with a cast iron body, providing excellent strength and corrosion resistance for demanding industrial environments. The lever-operated mechanism allows for quick and straightforward manual control, ideal for applications where frequent operation is required. The valve is designed to handle pressures from 0.6 to 1.6 MPa, offering flexibility for various system pressures.

Key Features and Technical Specifications:

Rugged Construction: The primary body and disc are made from high-grade cast iron, ensuring long service life and resistance to deformation under pressure.
Efficient Sealing: Equipped with a resilient seat (options include NBR, EPDM, or VITON) that provides a bubble-tight seal, minimizing leakage and ensuring system integrity.
Easy Operation: The lever handle provides a clear visual indication of the valve position (open/closed) and requires minimal effort to operate, reducing operator fatigue.
Bi-Directional Flow: The symmetrical disc design allows for installation in either flow direction, simplifying system design and installation.
Compact and Lightweight: Compared to gate or globe valves, the butterfly valve design offers a more compact profile, saving space and reducing structural support requirements.
Low Maintenance: Simple design with fewer moving parts translates to reduced maintenance needs and lower lifetime costs.

Frequently Asked Questions (FAQ)

Q: What is the main application for this lever-operated butterfly valve?
A: This valve is primarily used for on/off isolation and flow regulation in systems handling water, air, oil, and other non-aggressive fluids. Common applications include water treatment plants, irrigation systems, building services (HVAC), and general industrial piping.
Q: Can this valve be used for throttling (flow control)?
A: Yes, the lever-operated design allows for precise positioning of the disc, making it suitable for moderate throttling applications. However, for fine control over a wide range, a gear-operated valve might be recommended.
Q: What is the difference between wafer and lug type connections?
A: A wafer-style valve is installed between two flanges using longer bolts. A lug-style valve has threaded inserts (lugs) on the valve body, allowing it to be bolted directly to each flange, which can be beneficial for end-of-line service or system disassembly.
Q: What seat material should I choose?
A: NBR (Nitrile) is standard for water and oils at moderate temperatures. EPDM is excellent for hot water and mild chemicals. VITON (FKM) offers superior resistance to fuels, oils, and more aggressive chemicals. Selection depends on your media and temperature.
Q: Is this valve suitable for potable water applications?
A: With appropriate seat material certification (like EPDM compliant with drinking water standards, available upon request), it can be used in potable water systems. Please specify this requirement when ordering.
Q: What is the maximum operating temperature?
A: The maximum temperature depends on the seat material. With a standard NBR seat, it is typically up to 80°C. With EPDM, it can handle up to 120°C. Always confirm based on your selected seat material.
Q: Do you offer customization, such as different sizes or materials?
A: Yes, as a manufacturer, we can provide customized solutions. Sizes outside the standard range, different disc/stem materials (like stainless steel), or special coatings can be discussed based on your project needs.
Q: What is your typical delivery time?
A: For standard sizes and specifications, delivery time is generally competitive. It varies based on order quantity and current production schedule. We provide reliable lead times upon order confirmation and ship efficiently from our major ports.
