This flow divider is used to supply four independent hydraulic circuits with just one pump.
Division error approx. 3 %.
Equal pressure setting for all sections.
Valves adjustable from 70 - 210 bar, other setting ranges on request.
Modification to internal leak oil discharge possible - for this, close off port T with G1/2″ blind plug (modification recommended only after consultation!).
Configuration of gear flow dividers: qi = Q/z * 1000/n.
Qi = displacement/section [cm³].
Q = total input volume flow [l/min].
Z = number of sections.
N = rotating speed [rpm].

A hydraulic valve properly directs the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is determined by the position of a spool. A hydraulic system can only function - as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. The required size is determined by the maximum flow of the hydraulic system through the valve and the maximum system pressure

Directional Control Valves

Directional control valves can control the start, stop and change in direction of flow of a pressure medium (i.e. hydraulic oil). For this reason, they are also referred to as switching valves. Directional control valves are available as spool valves, poppet valves or rotary slide valves. Rotary slide valves, however, are no longer commonly used due to low operating pressure (up to 70 bar). Directional control valves without proportional control are referred to as switching valves.

Type of directional control valves:

• 1. Directional poppet valves
• 2. Directional spool valves
• 3. Check and non-return valves

Flow control valves manage the flow by decreasing or increasing the opening at the throttling point. This helps to determine speed of movement for the hydraulic actuators. The simplest design for a flow control valve is a needle or longitudinal slot mounted in the pipeline and connected to a screw that adjusts the opening at the throttling point. These are called throttle valves due to the fixed throttle, which changes the actual flow through the valve at varying loads.

Type of flow control valves:

• 1. Flow controls, pressure compensated valves
• 2. Flow controls, throttle valve
