Reduction valve 4458
Part of reduction valve are safety valves, which secure maximum allowable pressures in high pressure and medium pressure branch. Main working part of reduction valve is membrane. Output pressure is set by preload of membrane spring. During operation time, this pressure is secured by sealing of membrane regulation screw.
Reduction valve 4458 reduces air pressure in high pressure line of brake system to operating pressure, which maintains on constant size. It is designed and adjusted for buses KAROSA type 730. Any other purpose or different setting is necessary arrange with manufacturer.
