Product catalog summary
Application: The full lift safety valve by ZETKAMA is designed for use in power engineering, industry, and heating applications. It is suitable for air, other gases, and vapours, with outflow directly into the environment.
Features: The valve is made according to PN EN ISO 4126-1 standards, ensuring high tightness. It operates at a nominal pressure of 25 bar and a maximum temperature of 120°C. The nominal diameter ranges from DN 10 to 25, and the body material is brass (CuZn40Pb2).
Materials: The valve components include a nozzle, cap, disc, spindle, spring plate, adjusting screw plug, upper screw plug, and spring, primarily made from CuZn40Pb2 and 51CrV4 for the spring.
Dimensions: The valve is available in sizes DN 10, 15, 20, and 25, with corresponding weights and dimensions provided for each size.
Discharge Coefficients: The discharge coefficients for vapours and gases are provided for different DN sizes, with specific values for overpressure at 10%.
Capacity Table for Air: The document includes a detailed capacity table for air at 20°C, showing the capacity in kg/h for various set pressures and DN sizes.
Ordering Information: To order, use the product number (index) provided. The valve is available in normal types for gases and vapours with EPDM sealing, and the order example is given as 782 010 D.
Notes: The valve should be mounted in a vertical position. Data provided in the document can be changed without notice.
