Description
Right at the pump two functions have to come together, protection of system pressure and unloaded circulation during start-up. This size 16 pump safety block handles both in one housing, with a setting range of 6 to 315 bar and up to 300 l/min.
Advantages
- Pressure relief and solenoid unloading through a built-on directional spool valve in one block
- Setting range 6 to 315 bar, internal hexagon with protective cap against tampering
- 300 l/min maximum flow, 350 bar maximum operating pressure
- Flange connection for direct mounting on the pump housing
- Pressure valve in poppet seat design with tight closure
- 24 VDC supply, 3-pole connector (2 + PE) according to EN 175301-803, 7.83 kg weight
Application
The block sits on the pressure port of the pump in a hydraulic power unit and provides system protection there. During start-up and idle periods the solenoid circulates the oil without pressure, which cuts drive power and oil heating. The setting is made with an internal hexagon and secured by the protective cap.
