Subject: Line Break System, Line Break valve O&G Line Break System: This valve ensures closing of actuator on event of drop in pipeline pressure faster than expected. The needle screw on the top is used for setting the drop. ---- Line break system to close actuator in case of high pressure drop time (adjustable between 0.3 bar / min and 6.8 bar / min) ------------ The differential-pressure valve is a leakage free, block type poppet valve for use in line break-systems. -- -while the pressure drops turn the set- screw against clockwise (slowly) until the Line Break valve switches. Как обозвать это систему и клапан? Система/клапан контроля изменения/падения давления? спасибо |

Система отключения/отсечки/запирания линии (трубопровода). Клапан перепада давления (весьма возможно - управляемый по перепаду давления). |
