The RBHe-1 single-stage RB type helium regulator is a leverless regulator with variable outlet pressure regulation. They allow to reduce the pressure of gases taken from the cylinder to the required outlet pressure and ensure that this pressure is automatically kept as constant as possible, regardless of changes in inlet pressure.
RB regulators are suitable for the following gases: oxygen, acetylene, hydrogen, compressed air, nitrogen, carbon dioxide, argon, helium and propane-butane. They are equipped with safety valves through which excess gas is released from the outlet pressure chamber to the outside when the outlet pressure exceeds the acceptable limit.
Reducers are of the same design, but depending on the type of gas for which they are intended, they have different dimensions of internal and connecting elements. Combustible gas coupling nuts have left-hand threads and are marked with a hexagon notch.
The RBHe-1 helium reducer is a product recommended by us, repeatedly tested in operation.
