As a leading manufacturer in the valve industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance DIN 3352 PN16 Resilient Seated Gate Valve. Engineered specifically for demanding waterworks and municipal applications, this valve is designed to deliver reliable shut-off, long service life, and minimal maintenance in critical water distribution and treatment systems. With our commitment to quality certified by ISO9001 and years of experience serving global markets, we provide a robust solution that meets the stringent requirements of public utilities and infrastructure projects worldwide.
Our resilient seated gate valve stands out due to its superior sealing technology and durable construction. The key to its performance lies in the flexible, corrosion-resistant elastomer seat, which ensures a bubble-tight seal even after numerous cycles. This design not only prevents water loss but also reduces operating torque, making the valve easier to operate over its lifespan.
Key Features and Technical Advantages:
- Bubble-Tight Shut-off: The resilient seat provides excellent sealing against both low and high pressures, ensuring zero leakage and maximizing system efficiency.
- Low Operating Torque: The design minimizes friction between the gate and seat, allowing for smooth, easy operation with a standard handwheel, reducing operator effort.
- Corrosion Resistance: The valve body is typically manufactured from ductile iron with a high-quality epoxy coating, offering excellent protection against rust and corrosion in buried or aggressive environments.
- Bi-Directional Flow: Suitable for installation in either flow direction, providing flexibility in piping system design and layout.
- Minimal Pressure Drop: When fully open, the gate retracts completely into the bonnet, offering a full port and a straight-through flow path, resulting in very low pressure loss.
- Long Service Life & Low Maintenance: The resilient seat is designed to be wear-compensating, maintaining its sealing capability over time. The simple design has fewer wearing parts compared to other valve types.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of a resilient seated gate valve over a metal seated one for water applications?
A: The primary advantage is the bubble-tight seal achieved with minimal effort. The elastic seat compensates for minor imperfections and wear, ensuring zero leakage even after repeated cycling, which is crucial for conserving water and maintaining system pressure.
Q2: Is this valve suitable for both buried and above-ground installation?
A: Yes, it is designed for both. The standard epoxy coating on the ductile iron body provides excellent corrosion protection. For particularly aggressive soils or environments, optional enhanced coatings are available upon request.
Q3: Can this valve be operated with an actuator for remote control?
A: Absolutely. While supplied with a standard handwheel, the valve design is compatible with various electric, pneumatic, or hydraulic actuators. The mounting interface can be customized to fit your chosen actuator model.
Q4: What is the standard seat material, and are other options available?
A: EPDM (Ethylene Propylene Diene Monomer) is the standard seat material for potable water and general municipal use due to its good temperature range and resistance to aging. NBR (Nitrile) is a common alternative for applications involving oils or fuels. Other elastomers like Viton can be considered for specific media.
Q5: Are spare parts like seals readily available?
A: Yes. We maintain an inventory of critical spare parts, including complete seal kits (seat, stem seals). The design allows for relatively straightforward maintenance and seal replacement in the field if necessary.
Q6: Do you provide documentation like test certificates?
A: Standard documentation includes a material certificate and a factory test report (typically for shell strength and seat leakage). Additional certifications or specific test protocols can be discussed and arranged according to project specifications.
Q7: What are the available sizes for this DIN 3352 PN16 valve?
A: This valve series is commonly available in a wide range of sizes, typically from DN50 (2") up to DN600 (24") or larger. Please consult with our sales team for the complete size chart and availability.
Q8: How does your manufacturing capability ensure consistent quality?
A: Our production follows a strict ISO9001 quality management system. Every valve undergoes multiple quality checks, including dimensional verification, material inspection, pressure testing, and visual examination, ensuring each product meets the declared specifications and performance standards.
