Stopcocks
These stopcocks are designed for gaseous, explosive and toxic
mediums. After a hydraulic test, these stopcocks are additionally tested with
air. They are installed as locking devices to shut off a medium flow (service
water, steam, oil, petroleum and non-aggressive hydrocarbon oils). Due to their
small flow resistance, these stopcocks are indispensable for pipelines through
which a medium constantly passes at a high rate of speed.
