Static balancing valves zSTA Fig.221

Product catalog summary
Overview: The document provides technical specifications and details for the ZETKAMA zSTA balancing valve, designed for applications in heating, refrigeration, air conditioning, and industrial water systems. It emphasizes high tightness, reliability, and environmental friendliness.
Specifications: The valve is made from brass (CuZn36Pb2As) and is available in nominal diameters (DN) ranging from 15 to 50 mm. It can withstand a nominal pressure of 25 bar and a maximum temperature of 120°C. The valve features a Y-type threaded form and includes a non-rising brass stem and a composite control disc with EPDM.
Materials: Key components include a brass body, composite material cover, and EPDM gaskets. The valve also features a Venturi insert for precise flow measurement.
Dimensions: The document lists dimensions for various DN sizes, including length, height, and weight, with DN 15 being the smallest and DN 50 the largest.
Flow Measurement: The valve's flow characteristics are detailed with Kv values for different DN sizes, indicating the flow rate in cubic meters per hour.
Hydraulic Characteristics: Detailed hydraulic characteristics are provided for each DN size, highlighting the valve's performance under different flow conditions.
Settings: The document includes a table showing Kv values at different turns for each DN size, allowing for precise flow adjustments.
Ordering Information: Instructions for ordering include using the product number and specifying the desired DN size and pressure rating.
