Industrial Non-rising stem DIN Gate valves

Industrial non-rising stem DIN gate valves are gate valves designed and manufactured according to the standards set by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. These valves are commonly used in industrial applications where reliable flow control and adherence to standardized specifications are essential. Here’s a detailed overview:

  1. Design: DIN gate valves feature a non-rising stem design, where the stem remains stationary while the gate moves up and down within the valve body to control the flow of fluid. This design is space-efficient and suitable for installations with limited vertical space. The gate is typically wedge-shaped or parallel-sided and moves vertically to open or close the flow passage.

  2. DIN Standards: DIN gate valves are manufactured in accordance with DIN standards, which define the dimensions, materials, testing procedures, and performance requirements for various types of industrial valves. DIN standards ensure interoperability, compatibility, and quality consistency across different manufacturers and suppliers.

  3. Pressure Rating: DIN gate valves are available in various pressure ratings to suit different applications and operating conditions. Common pressure ratings include PN6, PN10, PN16, PN25, PN40, and PN64. The pressure rating of the valve should match the maximum operating pressure of the system to ensure reliable performance and safety.

  4. Materials: DIN gate valves are constructed from materials that comply with DIN standards and are suitable for the intended application and operating environment. Common materials include cast iron, ductile iron, carbon steel, stainless steel, bronze, and various alloys. The choice of material depends on factors such as the fluid being handled, temperature, pressure, and corrosion resistance requirements.

  5. Size Range: DIN gate valves are available in a wide range of sizes to accommodate different pipeline diameters and flow rates. Standard sizes typically range from DN40 to DN1200 or larger. The valve size should be selected based on the pipeline size and flow requirements of the application.

  6. End Connections: DIN gate valves are available with various end connections to suit different piping configurations and installation requirements. Common end connection types include flanged ends, butt weld ends, threaded ends, and socket weld ends. The choice of end connection depends on factors such as the piping material, size, and pressure rating.

  7. Applications: DIN gate valves are widely used in industries such as water supply, wastewater treatment, chemical processing, HVAC (heating, ventilation, and air conditioning), and manufacturing. They are suitable for both on-off and throttling applications and can handle a wide range of fluids, including water, steam, oil, gas, and chemicals. DIN gate valves are often specified in projects where adherence to standardized specifications is required.

  8. Actuation: DIN gate valves can be operated manually using a handwheel or equipped with pneumatic, hydraulic, or electric actuators for automated operation. Actuators provide remote control and can be integrated into control systems for process automation and optimization.

  9. Quality and Testing: DIN gate valves undergo rigorous quality control and testing procedures to ensure compliance with DIN standards and performance requirements. This may include hydrostatic testing, pneumatic testing, material testing, and dimensional inspection. Quality assurance measures help ensure the reliability, safety, and durability of DIN gate valves in industrial applications.

Overall, DIN non-rising stem gate valves are critical components used in industrial piping systems to control the flow of fluids. Their adherence to DIN standards ensures quality, reliability, and compatibility, making them suitable for a wide range of applications across various industries. Proper selection, installation, operation, and maintenance are essential to maximize the performance and efficiency of DIN gate valves in industrial processes.
