These pressure regulators, pressure reducers, filter regulators, filters and oilers can be used for pressures between approx. 40 and 400 bar. In mos cases the regulators are not designed as self-relieving, so that these do not blow into the surroundings with an overpressure on the secondary side. During operation of pressure reducers with high inlet pressures, the secondary side should be secured by a safety valve, as there, for example through leak in the valve, a higher pressure can exist than on the pressure reducer. Gases under high pressure are often used in welding technology. Special for this we offer pipeline pressure regulators, bottle pressure reducers acc. to DIN EN ISO 2503 and flashback arrestors acc. to ISO 5175.
