Safety valve, directly operated Type DBDH…1X/…XC…E

Valves of the type DBDH...1X/...XC...E are type-tested, directly operated pressure relief valves which conform to the Pressure Equipment Directive 97/23/EG. They are employed for reducing system pressure and are intended for use as safety valves. When the preset response pressure is exceeded in the P duct, the valves react and connect the P and T ducts internally. The valves are available in different versions: as screw-in valve “K” for screwing into blocks, as a valve with threaded connection “G”, or as a valve for subplate mounting “P”. The screw-in valve itself, which is used in all versions, basically consists of the sleeve, spring, cone or ball, valve seat and setting element.The spring presses the cone or the ball against the valve seat. The response pressure is factory-set to a fixed value using the setting element, then the valve is sealed.
