Description
A flow of up to 13000 l/min can only be relieved through a correspondingly large cross section. This pilot-operated pressure relief valve in size 150 holds pressure up to 16 bar at the set value and is built as a proportional pressure valve in poppet seat design.
Advantages
- Flow up to 13000 l/min through the size 150 flange connection
- Operating pressure up to 16 bar, relief to the set value
- Poppet seat design, closing tightly without permanent leakage
- Pilot-operated design with mechanical actuation, two switching positions
- Flange type 21 according to EN 1092-2, two ports in the direction P to T
- NBR seals for HL hydraulic fluid, 50 kg
Applications
Used in low-pressure circuits with very large oil volumes, such as cooling and filter loops or back-pressure lines of large power units. The EN 1092-2 flange connects the valve straight to the pipework without an intermediate manifold. Electrical connection is a 3-pole connector according to EN 175301-803.
