Industrial Products Pressure Valves Size 10 to 30 up to 315 bar up to 600 L/min Pressure Relief Valve Pilot Operated Type RB, RBE, Series 10 Data Sheet R-1002/10.98 GB Features ◊ Accurate movement, quick response and stability. ◊ Minimised flow pass resistance. ◊ Relatively small pressure override. ◊ Unloads smoothly without shocks if used with a non shock valve. ◊ For sub-plate mounting, porting pattern to DIN 24 340 Form E, ISO 6264 and CETOP-RP 121 H. Sub-plates must be ordered separately. ◊ Suitable for installation in manifolds. ◊ Three adjustment elements: rotary knob; sleeve with hexagon and protective cap; lockable rotary knob with scale and rotary knob with scale. ◊ Two pressure ratings. ◊ Solenoid operated unloading via a built-on directional spool valve. Type RBE Functional Description Type RB and RBE Series 10 Pressure Relief Valves are balance piston, seat type, relief valves that are used: ◊ To control the maximum pressure within a hydraulic circuit thus preventing overload of hydraulic circuit, hydraulic unit, pumps, etc. ◊ To control pressure within a hydraulic unit, e.g. load/unload hydraulic circuit pressure.

Pressure Valves Industrial Products Pressure Relief Valve Type RB 16 Type RB pressure relief valves primarily comprise a main valve (1) with main spool cartridge (3) and a pilot valve (2) with pressure adjustment element. The pressure present in channel A acts on the main poppet (3). At the same time, pressure is present at the control lines (6) and (7) with orifices (4) and (5) on the spring loaded side of the main poppet (3) and at the poppet (8) in the pilot valve (2). If the pressure in channel A rises above the value set at spring (9), poppet (8) opens against spring (9). The signal...

Industrial Products Pressure Valves Characteristic Curves Measure at ν = 36cSt and t = 50°C The Characteristic Curves were measured with external, zero pressure pilot oil drain. With internal pilot oil drain pressure, the inlet pressure increases by the outlet pressure present at port B.
