How it works
Quarter-turn lever
Two-way ball valve
Construction
Parts and materials
The ball valve is used as a shut-off/regulating valve in heating, water supply systems, in steam, fuel and pneumatic systems with compressed air and neutral gases. Installation of valves of this series is possible in systems transporting liquid and gaseous media (water, oil, oils, steam, air, alcohols, glycol, etc.), not aggressive to the materials of the valve.
Shut-off/regulation of the working flow is performed by means of the locking element, which is a ball with a special cross-section. The ball is rotated around the axis by means of a handle with a pointer mounted on the body. The valve is equipped with a scale with values. The selected position of the handle is secured with a nut. Measuring nipples are designed for connection of portable balancing and measuring devices, which allow measuring differential pressure, temperature and flow rate of the working medium. These instruments are used for balancing the network and setting the regulating valve. Network balancing - adjustment of the required pressures at different sections by adjusting the position of the shut-off valve regulating valve. The instrument is connected to the valve via measuring nipples and does not require draining the pipeline or stopping the network operation.
