The reducer is intended for controlled pressure reduction in networks where water, non-freezing glycol-based coolant, compressed air, other liquids and gases up to 110 ° C, non-aggressive to the materials of the product are used as the working medium. The principle of the gearbox – piston (spring). The pressure at the outlet of the water regulator is maintained at no higher than the set value, regardless of the pressure surges in the network. In static mode, the pressure after the gearbox also does not exceed the adjustment. By production of a pressure reducer the nickelized brass is used.
