Typical Applications of DIN PN16 Metal Seated Gate Valve
• Water treatment and distribution: municipal water supply, distribution networks, and water treatment plants.
• Chemical and petrochemical: process lines with corrosive media requiring metal-to-metal sealing.
• Power generation: cooling water, service water, and auxiliary systems in European-standard power plants.
• HVAC and district heating: large diameter pipelines for heating, ventilation, and air conditioning.
• High-temperature service: metal-seated design suitable for applications exceeding 200°C where soft-seated valves are not adequate.
• European and international projects: pipelines requiring DIN 3352 / DIN 3202-F5 / DIN 2543-2545 compliance.
FAQ - DIN PN16 Metal Seated Gate Valve
Q1: What is a metal seated gate valve?
A: A metal seated gate valve uses metal-to-metal contact between the wedge and seat rings for sealing. Unlike soft-seated (resilient) valves that use rubber or PTFE seats, metal-seated valves use hardfaced surfaces such as 13Cr or Stellite. This design makes them suitable for high-temperature and abrasive service where soft materials would degrade.
Q2: What is the difference between metal seated and soft seated gate valves?
A: Metal-seated gate valves use metal-to-metal contact for sealing, suitable for high-temperature service (above 200°C) and abrasive media, and resistant to wear and fire. Soft-seated gate valves use rubber or PTFE seats, providing bubble-tight sealing at lower temperatures but limited by the temperature rating of the soft material. Metal-seated valves generally require higher operating torque but offer longer service life in demanding conditions.
Q3: What materials are available for DIN PN16 gate valves?
A: Common body materials include GS-C25, 1.4308, 1.4408, WCB, LCB, CF8, CF8M, CF3, CF3M, WC6, WC9, C5, and C12. Various trim materials such as 13Cr, Stellite, and hard faced are available to suit different service conditions.
Q4: What is the difference between DIN PN16 and ANSI Class 150?
A: DIN PN16 and ANSI Class 150 are both low-pressure ratings, but they differ in standards. DIN uses European standards (DIN 3352 / DIN 3202-F5 / DIN 2543-2545) with metric DN sizes, while ANSI uses American standards with inch NPS sizes. Flange dimensions, face-to-face lengths, and materials (GS-C25 vs WCB) are different. Choose DIN for European projects and ANSI for American projects.
Q5: What end connections and actuation options are available?
A: End connections include flanged (RF) per DIN 2543-2545. Actuation options include manual handwheel, gear operated, and bare stem for electric actuator. Other options are available on request.
Q6: Why should a gate valve not be used for throttling?
A: Gate valves are designed exclusively for fully open or fully closed (isolation) service. Throttling can cause severe damage to the wedge and seating surfaces due to vibration, erosion, and wire drawing. Use a globe valve or dedicated throttling valve for flow regulation applications.
