ISO9001 Quality Management System
As a professional manufacturer with a strong export presence, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to offer our high-performance DIN 3352 Pneumatic Gate Valve. Engineered for demanding applications in water treatment and chemical processing, this valve combines robust construction with precise pneumatic control to ensure reliable isolation of aggressive and standard media. Since our establishment in 2016, we have focused on delivering industrial valves that meet rigorous international standards, supported by our ISO9001-certified quality management system. This valve is designed to provide long service life, minimal maintenance, and superior sealing performance, making it a cost-effective and dependable solution for your critical flow control needs.
Core Product Features & Technical Advantages:
- Durable Construction & Material Options: The valve body is manufactured from high-grade materials such as ductile iron, cast steel, or stainless steel (AISI 304/316), selected based on the specific fluid corrosivity and pressure requirements. This ensures excellent resistance to wear, corrosion, and pressure surges common in water and chemical plants.
- Precise Pneumatic Actuation: Equipped with a high-torque pneumatic actuator, the valve allows for rapid, remote, or automated opening and closing. Options include double-acting (for bi-directional control) or spring-return (for fail-safe open/close) configurations, enhancing process safety and control flexibility.
- Superior Sealing Performance: Features a parallel gate design with either metal-to-metal seats for high-temperature applications or resilient soft seats (like EPDM or PTFE) for bubble-tight shut-off in lower temperature services. This design minimizes leakage and ensures reliable isolation.
- Standard Compliance & Interchangeability: Manufactured in strict accordance with DIN 3352 standards for face-to-face dimensions and flange connections (DIN PN10/16/25/40). This guarantees easy installation and replacement within existing pipeline systems designed to European norms.
- Wide Application Suitability: Specifically engineered to handle a broad spectrum of media including raw water, treated water, wastewater, mild chemicals, acids, alkalis, and other industrial fluids, making it a versatile choice for multiple stages of treatment and processing plants.

Benefits for Your Operations:
- Enhanced Process Reliability: The robust design and tight sealing minimize downtime and leakage risks, ensuring consistent process performance in water treatment and chemical handling.
- Operational Efficiency: Pneumatic actuation enables fast cycle times and integration into automated control systems (SCADA, DCS), reducing manual labor and improving response times.
- Reduced Lifecycle Cost: High-quality materials and construction extend service intervals, while the standardized DIN design simplifies maintenance and spare parts procurement.
- Safety Improvement: The option for spring-return fail-safe actuators provides an added layer of safety by automatically moving the valve to a predetermined safe position (open or closed) in case of air supply failure.
- Global Compatibility: Adherence to DIN standards makes this valve suitable for projects worldwide, particularly in markets like Europe, the Middle East, and Asia where these specifications are prevalent.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a pneumatic gate valve over a manual one in water treatment?
A: Pneumatic actuation allows for remote, automated, and rapid operation. This is crucial in large-scale treatment plants for quick isolation, integration into process control loops, and reducing the need for manual intervention in potentially hazardous or hard-to-reach areas. -
Q: Can this valve handle corrosive chemicals?
A: Yes, when ordered with the appropriate material. For highly corrosive chemicals, we recommend selecting a stainless steel (AISI 316/316L) body and compatible seat materials like PTFE. Please provide the fluid composition and concentration for a precise material recommendation. -
Q: What does "DIN 3352" specify?
A: DIN 3352 is a German industrial standard that defines the face-to-face dimensions, flange connections, and basic design requirements for gate valves. Valves built to this standard ensure dimensional interchangeability and compatibility with other DIN/EN standard piping components. -
Q: Do you offer valves with different fail-safe modes?
A: Yes. Our pneumatic actuators are available in two main types: double-acting (requires air to open and close) and spring-return (fail-safe). The spring-return type can be configured to fail-open or fail-closed upon loss of air supply, enhancing process safety. -
Q: What is the typical lead time for an order?
A: Lead time depends on the valve size, material, and quantity. For standard configurations in popular sizes, we often have stock or a short production lead time. Customized orders may require additional time. A specific timeline will be provided with your quotation. -
Q: Are positioners or limit switches available?
A: Yes, these are common optional accessories. We can equip the actuator with mechanical or proximity limit switches for position indication and electro-pneumatic positioners for precise flow control. Please specify your requirements when inquiring. -
Q: What pressure of compressed air is required for the actuator?
A: The standard operating pressure for our pneumatic actuators is typically 4-7 bar (60-100 psi). The exact required pressure depends on the valve size and required torque; detailed specifications are provided in the technical datasheet for each model. -
Q: Do you provide documentation and certification?
A: Yes. Along with the product, we provide a test certificate (including shell test and seat test reports), material certificates, and a detailed operation manual. Our ISO9001 certificate demonstrates our commitment to a controlled quality management system.
