As a professional manufacturer specializing in industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance 3-Piece DIN 3357 Duplex Stainless Steel Ball Valve with ISO5211 Mounting Pad. Engineered for demanding applications, this valve combines the superior corrosion resistance of duplex stainless steel with a robust 3-piece design and standardized mounting interface, offering a reliable and long-lasting solution for critical flow control. Our commitment to quality, backed by ISO9001 certification, ensures that every valve meets stringent performance standards, making it a trusted choice for global clients across various industries.

Product Features & Technical Advantages:

Superior Corrosion & Erosion Resistance: Constructed from duplex stainless steel (grades like 2205 or 2507), this valve offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-containing environments. Its high strength allows for thinner, lighter sections without compromising durability.
Robust 3-Piece Design: The three-piece body construction allows for easy in-line maintenance and seat replacement without removing the valve from the pipeline. The bolted body connection provides a secure seal and facilitates servicing, reducing downtime and lifecycle costs.
Standardized Mounting & Actuation: The integrated ISO5211 mounting pad ensures effortless and secure attachment of a wide range of pneumatic, electric, or manual gear actuators from various manufacturers. This standardization simplifies automation, enhances compatibility, and provides flexibility for system upgrades.
Compliant Design: Manufactured in accordance with the DIN 3357 standard, this valve guarantees dimensional accuracy, pressure integrity, and performance consistency. This compliance assures compatibility with other DIN-standard components and provides a reliable benchmark for quality.
Versatile Sealing Options: Available with various seat materials such as PTFE, reinforced PTFE, or PPL for standard services, and metal seats for high-temperature or abrasive applications. This allows customization to handle a broad spectrum of media, temperatures, and pressures.
Low Operating Torque & Bubble-Tight Shut-off: The precision-machined ball and seats ensure smooth operation and reliable, bubble-tight sealing in both directions, minimizing pressure drop and ensuring efficient flow control.

Frequently Asked Questions (FAQ):

What are the main advantages of duplex stainless steel over standard 316 stainless steel?
Duplex stainless steels offer nearly double the yield strength and significantly better resistance to chloride-induced stress corrosion cracking and pitting corrosion compared to standard austenitic grades like 316. This makes them suitable for more demanding environments.
Can this valve be supplied with different end connections?
Yes. While commonly offered with threaded ends per DIN standards, we can provide flanged connections (ANSI, DIN, JIS) or other threaded standards (NPT, BSP) based on your specifications.
Is the ISO5211 mounting pad compatible with all actuator brands?
The ISO5211 is an international standard for actuator mounting. It ensures compatibility with actuators from most major manufacturers (e.g., AUMA, Rotork, Bernard, Neles). Always verify the specific actuator model's interface.
What is the lead time for an order of these valves?
Lead times vary based on order quantity, material grade, and configuration. Standard specifications typically have shorter lead times. Please inquire with your specific requirements for an accurate timeline.
How does the 3-piece design aid in maintenance?
The two body bolts can be removed, allowing the center section (containing the ball and seats) to be taken out for inspection or seat replacement while the end connections remain in the pipeline. This avoids the need to cut or disconnect the entire pipe.
What media is this valve suitable for?
It is designed for corrosive and aggressive media such as seawater, chlorides, acids, caustics, and process fluids in chemical, petrochemical, and offshore applications. The specific seat material must be selected based on the media and temperature.
Do you provide actuated versions of this valve?
Yes. We can supply the valve pre-assembled with pneumatic (double-acting or spring-return) or electric actuators. The ISO5211 pad simplifies this integration.
What quality certifications do you hold for manufacturing?
Our manufacturing processes are certified to the ISO9001 Quality Management System standard, ensuring consistent quality control throughout production.
