Check valve zCHE Fig.275

Product catalog summary
Specifications
The document provides technical specifications for ZETKAMA's wafer-type check valves, specifically types 275H and 275I. The valves are designed for various industrial applications, including shipbuilding, heating, power engineering, refrigeration, and air conditioning. They are suitable for use with glycol, industrial water, diathermic oil, steam, compressed air, and neutral fluids.

Materials
The body material for type 275H is brass (CuZn39Pb2), while type 275I uses stainless steel (GX5CrNiMo19-11-2). The disc and spring components are made of stainless steel, ensuring durability and resistance to high temperatures.

Pressure and Temperature Ratings
Type 275H has a nominal pressure of 16 bar and a maximum temperature of 200°C, while type 275I can withstand up to 40 bar and 300°C. The valves are available in nominal diameters ranging from DN15 to DN300.

Dimensions
The document includes detailed dimensions for each valve size, specifying measurements such as diameter, length, and weight for both types 275H and 275I.

Hydraulic Characteristics
The Kvs coefficients and opening pressures are provided for each valve size, indicating the flow capacity and pressure requirements for operation.

Ordering Information
To order, customers should use the product number (index) provided in the document. An example order is given for clarity, specifying the type, nominal pressure, nominal diameter, and material.

Additional Notes
The document notes that data can be changed without notice and emphasizes the compact, maintenance-free, and environmentally friendly design of the valves.
