As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable fluid control solutions for demanding industrial applications. Our DIN 3202 SS304 Butterfly Valve is engineered specifically for water treatment plants, offering a perfect balance of durability, performance, and cost-effectiveness. With years of experience since our establishment in 2016 and an annual export value reaching US$1.5 million, we understand the critical need for valves that can withstand corrosive environments while ensuring smooth operation. This valve is a testament to our commitment to quality, designed to meet the rigorous standards of global markets from North America to Southeast Asia.
This wafer-type butterfly valve is constructed from high-grade SS304 stainless steel, providing excellent resistance to corrosion and oxidation, which is crucial for long-term service in water treatment facilities. The compact and lightweight design of the wafer type makes installation between flanges straightforward, saving both time and space in your piping system.
- Superior Corrosion Resistance: The SS304 material ensures the valve body and disc are highly resistant to a wide range of chemicals and water-borne contaminants, extending the valve's service life significantly.
- Robust Sealing Performance: Equipped with a resilient EPDM seat as standard (NBR optional), the valve provides a bubble-tight shut-off, minimizing leakage and ensuring process integrity.
- Easy Operation and Maintenance: The manual lever operation allows for quick 90-degree rotation from fully open to fully closed. For larger sizes or higher torque requirements, a gearbox operator is available as an option, ensuring smooth and reliable control.
- Versatile Size Range: Available in a practical range from DN80 to DN200, this valve can be seamlessly integrated into various sections of your water treatment plant, from inlet screening to filtration and discharge.
- Standard Compliance: Manufactured in accordance with DIN 3202 standards and rated for PN10 pressure, ensuring compatibility and reliability in international projects.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of using a wafer-type butterfly valve?
A: The wafer-type design is compact and lightweight, allowing it to be installed between two pipeline flanges using bolts or studs. This saves space and simplifies installation compared to lug-type valves, making it a cost-effective choice for many applications.
Q2: Is this valve suitable for potable water treatment?
A: Yes. The SS304 stainless steel construction and standard EPDM seat material are commonly used and suitable for potable water applications. However, for specific regulatory requirements, material certifications can be provided upon request.
Q3: Can I use this valve with other fluids besides water?
A: The SS304 material offers good chemical resistance. Its compatibility with other media depends on the fluid's chemical properties, concentration, temperature, and pressure. Please consult our technical team with your specific fluid details for confirmation.
Q4: What is the delivery lead time for an order?
A: Lead times vary based on order quantity and valve configuration. Standard sizes are often available from stock. For precise delivery schedules, please contact our sales team with your requirements.
Q5: Do you offer valves with different seat materials?
A: Absolutely. While EPDM is standard for general water service, we offer alternative seat materials like NBR, Viton, or PTFE to handle different temperatures and chemical compatibilities. These are customizable options.
Q6: What is included with the valve upon delivery?
A: Typically, the valve is supplied as a complete unit. Optional accessories like hand levers, gear operators, limit switches, or mounting kits are available and should be specified at the time of ordering.
Q7: How does the pressure rating of PN10 relate to other standards like ANSI?
A: PN10 is a metric pressure rating equivalent to approximately 10 bar or 145 PSI. It is broadly comparable to Class 150 in the ANSI rating system for the given temperature range.
Q8: What kind of after-sales support do you provide?
A: We provide technical documentation, installation guidance, and responsive customer service. Should any issue arise, our team is ready to assist in finding a solution promptly.
