Safety valve zARMAK Fig.775

Product catalog summary
Application and Features
The document describes the Full Lift Safety Valve by ZETKAMA, designed for high tightness applications involving water, air, steam, and other neutral liquids, gases, and vapors. It is suitable for industries such as heating and power engineering.

Specifications
The valve is made according to PN EN ISO 4126-1 standards, with a nominal pressure of 16 bar and a maximum temperature of 200°C. The body material is nodular cast iron (EN-GJS-400-15), and it is available in nominal diameters DN 20-32.

Materials
The valve components include a body, seat, disc, lifting bell, bonnet, spindle, lifting cap, and spring, made from materials such as EN-GJS-400-15, X39CrMo17-1, X20Cr13, and 51CrV4.

Dimensions
The valve dimensions vary based on the nominal diameter, with specific measurements provided for DN 20x32, 25x40, and 32x50.

Installation Notes
Valves should be mounted vertically, and special considerations are required for condensate accumulation and blow-out installations.

Discharge Coefficients
Discharge coefficients are provided for different pressure ranges and valve types, indicating performance for vapors, gases, and liquids.

Pressure-Temperature Ratings
The valve operates within a pressure range of up to 16 bar and a temperature range of -10 to +200°C.

Types and Ordering
Various types of valves are available, including normal, gas-tight, marine, and reduced lift types, each with specific sealing and temperature characteristics. An example order format is provided for clarity.
