As a dedicated valve manufacturer with ISO9001 certified quality management since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Lever Operated Butterfly Valve DN150 PN1.6MPa. Engineered to the stringent GB/T3036 standard, this valve is designed for reliability and ease of operation in a wide range of industrial applications. With an annual export value reaching up to US$1.5 million, our products are trusted by partners across the globe, from North America and Europe to Southeast Asia and Africa. This specific model exemplifies our commitment to delivering robust, cost-effective flow control solutions that meet precise technical specifications and offer long service life.
This lever-operated butterfly valve is a cornerstone for on/off and throttling service in pipelines handling water, air, gas, and other non-aggressive media. Its compact design and simple 90-degree lever operation make it an efficient choice for manual control where quick shut-off is required. The valve is constructed to withstand a nominal pressure of 1.6 MPa (PN16) and features a nominal diameter of 150mm, making it suitable for a broad spectrum of mid-sized piping systems. The design ensures a tight seal and minimal pressure drop when fully open, contributing to system efficiency.
Key Features and Technical Advantages:
- Standard Compliant Design: Manufactured in full compliance with the Chinese national standard GB/T3036, ensuring dimensional interchangeability, material integrity, and performance reliability that meets recognized industry benchmarks.
- Robust Lever Operation: The manual lever actuator provides a simple, direct, and reliable method of operation. The position indicator on the lever clearly shows the valve status (open/closed), preventing operational errors.
- Durable Construction: The valve body is typically crafted from high-grade ductile iron or cast iron, offering excellent strength and corrosion resistance. The disc is often made from stainless steel or coated ductile iron for smooth operation and durability.
- High-Performance Sealing: Equipped with a resilient seat made from materials like EPDM (for water), NBR (for oil), or PTFE (for chemicals). This design ensures a bubble-tight seal in the closed position and provides excellent wear resistance.
- Compact & Lightweight: Compared to gate or globe valves of similar diameter, the butterfly valve design is significantly more compact and lighter, reducing installation space, structural support requirements, and handling costs.
- Bi-Directional Flow: The symmetrical design of the disc allows for effective sealing against flow from either direction, providing flexibility in pipeline layout and installation.
- Low Maintenance: The simple design with minimal moving parts translates to lower maintenance needs and costs over the valve's lifecycle. The stem is sealed with O-rings or packing to prevent leakage.

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 and regulating service in pipelines carrying water, air, gas, and other non-corrosive fluids at moderate temperatures and pressures. It is common in HVAC, water treatment, irrigation, and general industrial plumbing systems. -
Q: Can this valve be used for throttling (flow control)?
A: Yes, the lever-operated design allows for precise positioning, making it suitable for throttling applications. However, for frequent or precise throttling, a gear operator might be recommended to reduce operator effort. -
Q: What is the difference between Wafer and Lug type connections?
A: A Wafer-style valve is sandwiched between two pipe flanges using long bolts. A Lug-style valve has threaded inserts (lugs) on the valve body, allowing it to be bolted to each flange independently, which is beneficial for end-of-line service or easier maintenance. -
Q: How do I select the appropriate seat material (EPDM, NBR, PTFE)?
A: The choice depends on the media and temperature. EPDM is excellent for hot/cold water and mild chemicals. NBR is suitable for oils and fuels. PTFE offers the widest chemical resistance and higher temperature range. Please consult our technical team for your specific media. -
Q: Is this valve suitable for potable water systems?
A: Yes, when configured with an EPDM seat that complies with relevant drinking water standards (certificates available upon request), this valve is suitable for potable water applications. -
Q: What is the lead time for this product, and what are the shipping options?
A: Standard models are typically available from stock or have a short production lead time. We ship globally from major Chinese ports like Shanghai, Guangzhou, and Hong Kong, offering flexible logistics solutions tailored to your needs. -
Q: Do you provide customization, such as different end connections or materials?
A: Yes, as a manufacturer, we offer customization options. Modifications to end connections (flanged, grooved), special coatings, or alternative materials can be discussed and provided based on your project requirements. -
Q: What quality assurance do you provide?
A: Our manufacturing process is ISO9001 certified. Each valve undergoes pressure testing (shell test and seat test) according to the standard before shipment. Test reports can be provided.
Backed by our ISO9001 certification and nearly a decade of manufacturing expertise since 2016, Shanghai Zhibang Valve guarantees a product built to last. Our global reach, serving markets from North America and Europe to Africa and Oceania, is a testament to the reliability and acceptance of our valves.
