Welcome to Shanghai Zhibang Valve Manufacture Co., Ltd. — a professional valve manufacturer established in 2016 with an annual export value exceeding US$1 million. We supply reliable, high-performance butterfly valves to markets across North America, South America, Europe, Southeast Asia, Africa, the Middle East, and Oceania. Our Ductile Iron Body Butterfly Valve PN10 DIN 3202 with Stainless Steel Shaft is designed to deliver outstanding corrosion resistance, long service life, and precise flow control for industrial and municipal applications.
This butterfly valve combines a robust ductile iron body with a stainless steel shaft, ensuring durability in corrosive environments such as water treatment, HVAC systems, and chemical handling. The valve conforms to DIN 3202 K1/K2 face-to-face dimensions and supports PN10 pressure rating, making it compatible with standard European pipeline systems. Whether you need a wafer or lug type, the valve can be configured to meet your specific requirements.
Key Features & Technical Specifications
- Ductile Iron Body (GGG40/GGG50): High tensile strength and impact resistance, ideal for pressure applications up to PN10.
- Stainless Steel Shaft (SS304 or SS316): Excellent corrosion resistance against moisture, chemicals, and aggressive media; reduces maintenance frequency.
- ISO 5211 Top Flange: Allows direct mounting of actuators (manual, electric, or pneumatic) without additional brackets.
- Replaceable Resilient Seat: EPDM, NBR, or PTFE linings available for bubble-tight shut-off and compatibility with various fluids.
- Low Torque Operation: Streamlined disc design minimizes operation torque, reducing actuator size and cost.
- Full Compliance with DIN 3202 PN10: Ensures interchangeability and easy installation in European standard systems.
- Bidirectional Sealing: The valve provides reliable shut-off in both flow directions.

Frequently Asked Questions (FAQ)
-
What is the maximum temperature this valve can handle?
The standard temperature range is -10°C to +120°C. For higher temperatures up to +180°C, a PTFE or Viton seal can be provided upon request. -
Can the valve be used for drinking water?
Yes, with an EPDM seat that meets WRAS or KTW approval (available as an option). Please specify when ordering. -
What is the difference between wafer and lug types?
Wafer type is clamped between two pipe flanges and requires both flanges for installation. Lug type has threaded inserts on the body, allowing isolation of one side for maintenance without disturbing the other pipe. -
Do you offer actuators with the valve?
Yes, we can supply manual worm gear, electric, or pneumatic actuators. The valve top flange conforms to ISO 5211, and we can provide complete assembled units. -
What is the face-to-face dimension for DN200 PN10?
According to DIN 3202 K1, the face-to-face for DN200 is 71 mm (standard). For lug type K2, it is also 71 mm. Please confirm your specific standard. -
How does the stainless steel shaft improve corrosion resistance?
The shaft is made of SS304 or SS316, which forms a passive oxide layer that protects against rust and chemical attack. This eliminates shaft pitting common with carbon steel shafts in humid or corrosive environments. -
Is the valve bidirectional?
Yes, the resilient seat design provides bubble-tight shut-off in both flow directions, up to the rated pressure. -
Can I get a sample order before bulk purchase?
Certainly. We support sample orders for testing and qualification. Standard sizes are in stock for quick delivery.
