■■ Nominal pressures to ≤ 25 bar
■■ Operating temperature ≤ 50 °C
Description
Stopcocks provide the opportunity to either vent the connected pressure gauge according to the position of the handle (venting position), i.e. put it into a pressure-free state, or to vent the pressure measuring instrument under pressure (operating position) or to let the medium escape (blow
position). The table on page 2 lists the nominal pressure PN for each version. For higher pressures shut-off valves must be used.
Test connection version
Stopcocks with test connection are intended for the simultaneous connection of operating pressure measuring instruments and test connection pressure gauges to thepressure pipeline. With this version, the third route, which leads to the outside at the standard version, is used as connection for a test connection pressure gauge. A fourth position of the handle enables the simultaneous connection of the operating and the test connection pressure measuring instruments to the pressure pipeline.
