Pressure Relief Valve L-DB50F2-3X/16YUSO555 - Bosch Rexroth R900506042

Cooling and circulation circuits with high flow have to be protected against overpressure without the relief itself becoming the bottleneck. The L-DB50F2-3X/16YUSO555 passes up to 1500 l/min and limits the pressure to a maximum of 16 bar.

Advantages

• Flow of up to 1500 l/min in size 50, laid out for circuits with heavy oil circulation.
• Pilot-operated poppet seat design keeps the path from P to T tight up to the set pressure.
• Pressure adjustment range of 3.8 to 16 bar through an internal hexagon with a protective cap, which guards the setting against accidental change.
• Flange connection to flange type 21 according to EN 1092-2 across three ports.
• Weight of 15 kg with NBR seals for hydraulic fluid HL.

Application

The valve protects circulation, cooling and filter circuits of large power units against overpressure. The flange connection takes the large line cross sections that a flow of 1500 l/min demands. The set pressure is adjusted by hand through the internal hexagon.

Manufacturer

Bosch Rexroth builds the valve under material number R900506042.
