Overview

Full bore ball valves MVI of the BV.51 ... series belong to shut-off valves and are not designed to regulate the flow. They perform the function of fast shut-off of the flow on domestic pipelines hot and cold systems water supply, heating. Do not create resistance to flow Use ball valves as control valves is prohibited. Built-in manual air vent and drain the branch pipe allows you to use the valve as a shut-off and drainage fittings on risers, replacing the traditionally used a combination of a conventional ball valve (valve) and a tee with a plug

Model overview

Those. information

Valves must be operated at pressure and temperature, set out in the table of technical characteristics. It is strictly forbidden to allow the working environment to freeze. inside the tap. When draining the system in winter, the valve must be left half-open so that the work environment does not remain in cavities behind the shutter. Ball valves are operated simultaneously with only one maximum parameter (pressure or temperature). Use product with simultaneous parameters is prohibited.
