As a professional valve manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Stainless Steel Gate Valve designed specifically for demanding water treatment applications. Engineered in strict accordance with the DIN 3352 standard and rated for PN16 pressure, this valve is built to provide dependable, leak-tight shut-off in corrosive and high-purity fluid systems. Since our establishment in 2016, we have focused on delivering robust fluid control solutions that meet the precise needs of industrial clients worldwide. This valve exemplifies our dedication, combining premium stainless steel construction with advanced anti-corrosion features to ensure long-term performance and minimal maintenance in your critical water treatment processes.
The core value of this valve lies in its exceptional durability and sealing integrity. It is an ideal choice for applications where fluid purity and system reliability are non-negotiable. Let's delve into the specific features and benefits that make this product a superior investment for your operations.
Detailed Product Features & Technical Specifications:
- Superior Corrosion Resistance: Manufactured from high-grade stainless steel (typically 304 or 316, customizable upon request), the valve body, bonnet, gate, and stem are all highly resistant to oxidation and corrosion from water, mild chemicals, and atmospheric conditions. A specialized passivation treatment further enhances the surface's protective oxide layer.
- Robust DIN 3352 Design: Compliance with the DIN 3352 standard ensures dimensional interchangeability, reliable flange connections, and proven pressure-containing design principles. This provides peace of mind regarding compatibility and safety within European and international piping systems.
- Reliable PN16 Pressure Rating: The valve is designed and tested to withstand a nominal pressure of 16 bar, making it suitable for a wide range of municipal and industrial water treatment pressures, including filtration, backwashing, and distribution lines.
- Excellent Sealing Performance: Features a precision-machined gate and seat. Options include resilient seats (e.g., EPDM) for bubble-tight shut-off in lower-temperature applications or metal-to-metal seats for higher temperature resilience.
- Easy Operation & Maintenance: The rising stem design with a handwheel allows for clear visual indication of valve position (open/closed). The standardized design facilitates easy maintenance, seat replacement, and parts sourcing if needed.
-
Versatile Application Scope: Primarily designed for water treatment systems, it is perfectly suited for:
- Potable water treatment and distribution
- Wastewater treatment plants
- Industrial process water lines
- Desalination plants
- Cooling water systems

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a DIN 3352 gate valve?
A: The primary advantage is standardization. DIN 3352 specifies dimensions, pressure ratings, and testing, ensuring interchangeability with other compliant valves, simplifying procurement, installation, and maintenance in systems designed to European standards. -
Q: Can this valve be used with fluids other than water?
A: Yes, while optimized for water treatment, it can handle other mild, non-aggressive fluids like oils, gases, or steam within its pressure and temperature limits. Material compatibility for specific chemicals should be verified upon request. -
Q: What is the difference between PN16 and Class 150 ratings?
A: PN16 is a metric pressure rating (16 bar at room temperature). Class 150 is an ASME rating (~19.6 bar at a specific temperature). They are similar but not identical. It's crucial to specify the required standard for your project. Our valve is rated PN16 per DIN. -
Q: Is the valve suitable for underground burial or outdoor installation?
A: The stainless steel construction offers good resistance to atmospheric corrosion. For direct burial or highly corrosive environments, specifying 316 stainless steel or additional protective coatings is recommended. -
Q: Do you offer actuators for automated operation?
A: Yes, this manual gate valve can be fitted with electric or pneumatic actuators as an optional feature. Please provide your automation requirements (voltage, torque, signal) for a customized solution. -
Q: What are the available sizes?
A: We typically stock a range of common sizes from DN50 (2") to DN300 (12"). Other sizes within the DIN 3352 range can be produced based on order quantity and lead time. -
Q: How do I ensure I get the correct flange facing?
A: Standard delivery is with Raised Face (RF) flanges per DIN EN 1092-1. Flat Face (FF) or other types are available. Clearly specify your piping flange standard and facing type when inquiring or ordering. -
Q: What is your typical delivery time?
A: For standard sizes and materials, delivery can be relatively quick. Exact lead times depend on current stock levels, order quantity, and customization requirements. We provide reliable schedules upon order confirmation.
