Ball valves are designed to close and open the flow of liquid and gaseous media, both non-aggressive and aggressive (applies to acid-resistant valves), such as gases, including those according to PN-C-04750:2011, air, exhaust gases, water, crude oil, oils, kerosene, gasoline, etc.

Operating temperature ranges, depending on the type of working medium, maximum working pressure, and seals used, range from -30°C to +200°C, with the ZC-6 DN80 model ranging from -30°C to +100°C. For aggressive media, the type of medium (chemical composition) and related operating parameters should be agreed upon when ordering. Ball valves can be used in a variety of installations, primarily water, gas, and heating systems, as well as in the chemical (acid-resistant valves) and petrochemical industries.

Special-purpose valves include manometer ball valves, cat. no. ZC-4, ZC-5, ZC-4E and ZC-5E, which are designed for pressure gauges used in measuring devices. Ball valves, cat. no. ZC-1; ZC-2; ZC-3; ZC-6 can be manufactured in the following versions: - with columns, cat. no. K-1; K-2; K-3; K-4, intended for underground installations, - with stem extension columns (moving the control point by a certain distance), cat. no. K-5; K-6; K-7; K-8, intended primarily for heating engineering. The scope of application of ball valves is in accordance with the "pt" (pressure – temperature) operating diagrams. Special factors or application conditions may result in a reduction of the permissible working pressure.
