Pressure Relief Valves (KRACHT)
DV
The DV pressure valves are hydraulically pilot-controlled valves. They comprise a main valve and one or several pilot-controlled valves. The modular design permits using different pilot control valves which means a multitude of functions can be implemented. Along with pressure limiting and pressure control functions, this also includes special solutions such as pressure range switching valves and valves with electric relief. Typical application areas are oil hydraulics and lubrication technology.
- Operating pressure p = ...210 bar
- Nomical size 50 / 80
- Max. flow capacity pQ = ...1800 l/min
DBD
The pressure relief valve DBD is a directly-operated poppet valve for installation in the pipe lines or as a clamp-in valve. The valve is used to safeguard the pressure of hydraulic systems up to pmax=400bar. For line installations the housing has two connections with Whitworth pipe threads. Without housing, the valve cartridge can alternatively be screwed into the specified bore contour in any body desired.
DBD 06/08:
- Operating pressure p = ...400 bar
- Max. flow capacity pQ = ...40 l/min
DBD 10:
- Operating pressure p = ...400 bar
- Max. flow capacity pQ = ...80 l/min
DBD 20:
- Operating pressure p = ...345 bar
- Max. flow capacity pQ = ...200 l/min
HV / HVF
The pilot operated, sliding piston pressure relief valve HV/HVF is intended for inline mounting and is suitable to safeguard mean pressure hydraulic circuits up to 160 bars. The pipe connection is to be effected either by SAE-Mounting Surfaces (3000 psi) or by Whitworth Pipe Threads “G”. Due to the design principle of sliding piston piloting the valve is also suitable for higher viscosities.
- Operating pressure p = ...160 bar
- Max. flow capacity pQ = ...350 l/min
SPV / SPVF
The pressure relief valve SPV/SPVF is a direct spring sliding piston valve. It is intended for mounting in pipelines and is suitable to safeguard low pressure hydraulic circuits. The pipe connection is to be effected either by SAE-mounting surfaces (3000 psi) or by Whitworth pipe threads ”G“.
- Operating pressure p = ...30 bar
- Max. flow capacity pQ = ...800 l/min
