Oxygen pressure regulators with network power switching and light-sound pressure drop alarm

Oxygen pressure regulators with network power switching and a light and sound pressure drop alarm (hereinafter referred to as the switch), are designed to reduce high pressure coming from two sources: main and backup, to a set value and uninterrupted supply of oxygen to the low pressure network due to automatic switching between sources. The switch is equipped with an alarm with a visual indicator and an audible signal. The power source can be cylinders or manifolds, the collectors of which must be equipped with shut-off valves. TECHNICAL CHARACTERISTICS Working gas Oxygen The highest pressure at the inlet, MPa (bar) 20,0 (200) Operating pressure of the main source, MPa (bar) 1,2 (12)±10% Working pressure of the backup source, MPa (bar) 1,0 (10)±10% Maximum capacity, m3/ h 40 Safety valve activation pressure, MPa (bar) 1,4 (14)±10% Alarm trigger pressure, MPa (bar) (yellow indicator, intermittent signal) 2,0 (20)±10% Critically low pressure, MPa (bar) (red indicator, continuous signal) 0,6 (6)±10% Operating voltage, V 220/5 Connection dimensions at the entrance W21,8х1/14’ Connection dimensions at the outlet G ½-B Overall dimensions, no more, mm 380x315x130 Weight, not more, kg 8 SUPPLY KIT Marking Item Order No. Q-ty* PP21.009 –880.00.000 Oxygen pressure regulator with semi-automatic power supply switching 880.000.00 1 PP21.009 –880.00.000ЕТ Manual – 1 Pad 006.011.03 6
