Oxygen pressure regulator RO-200-V DM W21.8-G1/4
The oxygen pressure regulator is designed for reducing, regulating and automatically keeping up preset working pressure of oxygen for gas welding, cutting, brazing or heating.
MAIN SERIES ADVANTAGES:
► Brass body ensures strength and durability of the design.
► pressure gauges Ø50mm in bar.
► Easy adjustment of working pressure due to comfortable knob.
► Highly durable reducing unit ensures fault-free operation.
► Shutoff valve at the pressure regulator outlet allows to maintain the working pressure settings during work intervals without closing the cylinder valve.
► Extended connection unit allows to install the pressure regulator at different types of cylinders.
► Due to vertical positioning of the knob, the operator’s hand does not block the view of the gauges’ readings during adjustment.
► With the regulator installed at the cylinder, pressure gauges are conveniently positioned for making adjustments and monitoring gauge readings.
