As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is committed to delivering high-performance and reliable flow control solutions for demanding industrial applications. Our DIN 3352 Electric Gate Valve is engineered specifically for the rigorous requirements of power plant cooling water systems. This valve ensures precise on/off control, robust sealing, and long-term operational stability, helping to maintain the efficiency and safety of your critical cooling infrastructure. With years of experience serving global markets, we understand the need for durable components that withstand continuous operation under varying pressures and temperatures.
This electric gate valve offers significant advantages for power plant operations. Its design focuses on reliability and ease of integration into automated control systems.
- Robust Construction: Manufactured from high-grade materials such as cast iron, ductile iron, or cast steel, the valve body provides excellent resistance to corrosion and mechanical stress commonly encountered in cooling water pipelines.
- Precise Electric Actuation: The integrated electric actuator allows for remote operation, enabling seamless integration with plant Distributed Control Systems (DCS) or Supervisory Control and Data Acquisition (SCADA) systems. This eliminates the need for manual intervention in hard-to-reach areas.
- Superior Sealing Performance: Utilizing seats made from materials like stainless steel or EPDM, the valve ensures bubble-tight shut-off, preventing leakage and water loss, which is critical for maintaining system pressure and cooling efficiency.
- Low Maintenance Design: The gate valve's straightforward design minimizes wear parts and simplifies maintenance procedures, reducing downtime and total cost of ownership over the valve's lifecycle.
- Compliance with International Standards: Conforming to DIN 3352 standards ensures dimensional interchangeability, reliable performance metrics, and compatibility with other pipeline components in your system.
To help you specify the correct valve for your application, here are some typical technical specifications:

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of an electric actuator over a manual one for this gate valve?
A: The electric actuator enables remote and automated operation. This is crucial in power plants for integrating valves into central control systems, allowing for quick isolation of pipeline sections without sending personnel to potentially hazardous or difficult-to-access locations, thereby enhancing safety and operational efficiency.
Q2: Is this valve suitable for seawater or brackish water in coastal power plants?
A: Yes, but material selection is key. We offer body materials like cast steel (WCB) and seat/seal materials such as stainless steel or specific elastomers that provide enhanced corrosion resistance. Please specify your medium's exact properties so we can recommend the most suitable material combination.
Q3: Can you provide valves with different flange standards, like ANSI, instead of DIN?
A: Absolutely. While this product line is based on DIN 3352, we can manufacture gate valves to other international standards, including ANSI, JIS, or BS, upon request. Flange dimensions and pressure ratings can be customized to match your existing pipeline specifications.
Q4: What is the typical lead time for an order of these valves?
A: Lead time depends on the order quantity, size, and material specifications. Standard configurations often have shorter lead times. We recommend contacting our sales team with your specific requirements for an accurate production and delivery schedule.
Q5: Do you offer any warranty or after-sales support for these valves?
A: Yes, we provide a standard warranty on our products against manufacturing defects. Furthermore, we offer technical support for installation, operation, and maintenance. Detailed documentation, including manuals and datasheets, is provided with each shipment.
Q6: How is the electric actuator controlled? Can it receive signals from a PLC?
A: The actuator can be configured for simple on/off control via a dry contact or can be equipped to receive and send standard control signals (e.g., 4-20mA, 0-10V) and feedback signals (open/close, torque alarm) for seamless integration with Programmable Logic Controllers (PLCs) and plant control networks.
Q7: What maintenance does this electric gate valve require?
A: Maintenance requirements are minimal. Periodic checks of the actuator's electrical connections and lubrication (if specified) are recommended. The valve itself, due to its robust design, typically requires only occasional operational checks and seal inspection/replacement after extended service periods, which contributes to low lifecycle costs.
Q8: Can you provide customized valves with special coatings or painting for harsh environments?
A> Yes, customization is one of our strengths. We can apply epoxy coatings, galvanization, or other specialized paint systems to the valve body to provide extra protection against corrosive atmospheres or specific chemical exposures in your plant environment.
