Pressure Relief Valve DB52F2-3X/100YU - Bosch Rexroth R900353053

This valve limits the pressure of a circuit to no more than 100 bar. As a pilot-operated poppet seat valve it stays largely free of leakage when closed, and when open it discharges up to 2000 l/min. Maximum operating pressure is 315 bar.

Benefits

• Poppet seat design with low leakage in the closed state
• Adjustment range 3.9 to 100 bar, internal hexagon under a protective cap
• Up to 2000 l/min flow in size 52
• Three ports on the flange connection, hydraulic actuation
• 27.1 kg weight, NBR seals for HL hydraulic fluid

Application

It makes sense wherever a circuit stands under pressure for long periods and leakage would drive up oil temperature. The protective cap holds the set value. The size 52 flange takes high flows without a throttling point.

Manufacturer

Bosch Rexroth lists the valve under material number R900353053. Curves and the dimension drawing are in the DB52 series documentation.
