Double shut-off valve 7MF9401-...
The shut-off valves for pressure measuring devices are used to shut off the medium line for corrosive and non-corrosive gases, vapors and liquids.
Дизайн
A siphon is installed in front of the shut-off valve for media with temperatures above 120 °C. The form B shut-off valves have a shaft with which a measuring instrument holder can be attached. No adapter is therefore required for fastening these valves. With DN 5 double shut-off valves, the air-release/test connection can be shut off. This enables a zero point check on the pressure measuring device. In addition, a characteristic curve test can be conducted on the pressure measuring device using an external pressure sensor. The valve packing material is PTFE.
Характеристика
Permissible operating overpressure depends on the permissible operating temperature
