Shanghai Zhibang Valve Manufacture Co., Ltd (established in 2016) is a specialized manufacturer of high-quality industrial valves, exporting globally with an annual export value of US$1 Million to US$1.5 Million. Our Manual Lever and Gear Operated Butterfly Valve PN16 DIN 3202 is engineered for general industrial service, delivering reliable performance, easy operation, and long service life. Backed by ISO9001 certification, each valve undergoes strict quality control to ensure consistent performance across diverse applications. This valve is designed to meet the demands of water treatment, HVAC, chemical processing, and other general industries.
The valve combines two operation modes: a lever for quick, manual open/close in low-pressure scenarios and a gearbox for precise, torque-multiplied operation under higher pressure or larger sizes. This dual-mode design provides flexibility and reduces operator effort. Conforming to DIN 3202 standard, the valve is fully interchangeable with other compliant components, simplifying system integration. The compact wafer or lug body design minimizes space requirements and allows easy installation between flanges.
Key Features & Benefits
- Dual Operation: Lever for quick action, gearbox for smooth and precise throttling – ideal for different flow control needs.
- Bubble-Tight Shut-Off: Advanced seat design ensures zero leakage, meeting stringent industry requirements.
- Wide Material Options: Body available in cast iron, ductile iron, or stainless steel; disc in stainless steel (CF8/CF8M); seat in EPDM, NBR, or PTFE for compatibility with various media (water, oil, gas, mild chemicals).
- Low Torque Design: Optimized disc and seat geometry reduces operating torque, extending the life of the gearbox and lever.
- Corrosion Resistance: Optional coatings and disc materials ensure durability in harsh environments.
- Simple Maintenance: Easy disassembly and replacement of seat and seals without special tools.

Frequently Asked Questions (FAQ)
-
Q: What are the advantages of gear operation over lever only?
A: Gear operation multiplies torque, making it easier to open/close larger valves under high pressure. It also allows precise throttling and reduces physical effort. Our valve includes both options; the lever is for quick action, the gearbox for demanding conditions. -
Q: Can this valve be used for hot water or steam?
A: Yes, with the appropriate seat material. For hot water up to 120°C, EPDM seat is suitable. For steam applications, we recommend a PTFE seat (up to 200°C). Please specify your operating conditions when ordering. -
Q: Is the valve suitable for drinking water systems?
A: Yes, the EPDM and NBR seat materials comply with WRAS and other drinking water standards. The cast iron body can be epoxy coated for additional protection. Please request drinking water grade certification. -
Q: What certifications does your company hold?
A: We are ISO9001 certified. Our valves are also tested according to EN 12266 (leakage testing). Custom certifications (e.g., CE, ATEX) can be arranged upon request. -
Q: What is the typical lead time?
A: For standard sizes DN50-DN300, lead time is 15-20 working days. Larger sizes and custom materials may require 25-35 days. We maintain stock for popular models. -
Q: Can I get a sample for testing?
A: Yes, samples are available for qualified buyers. Please contact our sales team for details. Sample orders have a reduced lead time. -
Q: How do I select the correct valve size and material?
A: Provide us with your media type, operating pressure, temperature, and pipe size. Our engineering team will recommend the optimal configuration. We also offer technical datasheets for reference. -
Q: What is the warranty period?
A: We offer a 12-month warranty from shipment date against manufacturing defects. Extended warranty options are available on request.
