General
Pump safety blocks type DBA are pilot-operated pressure relief valves which are integrated into a block and intended to be mounted directly onto SAE pressure ports of pumps.
It is used for limiting (type DBA) the operating pressure.
Pump safety blocks generally consist of valve block (1) and pressure limitation screw-in cartridge valve type DB 20 K (2) (data sheet 25818). Optionally, a pressure switch type HED 8 (3) (data sheet 50061) can be installed on the valve block.
The valve housing is equipped with a port P for hydraulic fluid input and port P1 for hydraulic fluid output. In a branch of the through connection between these two ports, the pressure limitation screw-in cartridge valve can be found. By opening this valve, a connection to port T (tank line) is established.
At the standard model, connection diagram NG6 is covered with the cover plate (4). The pressure in the through connection (P - P1) has an effect on the main control spool (5) of the pressure limitation screw-in cartridge valve.
Via the nozzle bores (6 and 7), the pressure is at the same time applied to the poppet (8). If the pressure in port P exceeds the value set at spring (9), the poppet (8) opens against the spring (9).
Via the nozzle bores (6 and 7), the hydraulic fluid from channel P flows into the spring chamber (10) and is here internally directed via the control line (11) into the tank.
Due to the state of equilibrium at the main control spool (5), hydraulic fluid flows from channel P to channel T, maintaining the set operating pressure.
A pressure gauge connection (12) allows for the control of the operating pressure.
Pump safety block type DBA…D (with pressure switch)
The use of an electrical pressure switch type HED 8 (3) (data sheet 50061) enables activation and deactivation of an electric circuit via the control line (13).
In basic design, the control line (13) is closed with a plug screw (14).
The pressure gauge connection M and tank port T are illustrated with an offset of 90 °!
- Zero-pressure start-up and circulation of the pump
- Intended for direct mounting onto the SAE pressure port of the pump
- Low circulation pressure due to short distance
- Low compression volume for soft switching to depressurized circulation
- Quick pressure build-up
- 4 adjustment types for pressure adjustment, optionally
• Rotary knob
• Sleeve with hexagon and protective cap
• Lockable rotary knob with scale
• Rotary knob with scale - 5 pressure ratings, optional
- Low noise level due to direct flange mounting at the pump
