Section Distributors

Group (section) distributors are building elements (line HP has 1 – 10 sections, line JR 16 - 6 sections) designated for controlling the direction and flow rate of the working fluid in hydraulic circuits. There exist various control options – manual/mechanical, bowden, hydraulic, pneumatic … and a broad range of internal connections providing for various applications, such as hydraulic circuits of high-lift carts, auxiliary hydraulic lifting and manipulation mechanisms in trucks, tractors, slide loaders, etc.

On SPECIAL ORDER basis, our Division of Customized Hydraulics is able to supply also:

Section Distributor HP-12,

All modifications of this component are designated for controlling the direction and safe control of the flow rate in hydraulic systems, type OC (open centre). The hydraulic section distributor, model OC, can be delivered in modification for serial connection of two or more distributors. The delivery include a safety valve in each section with optional choking of the work fluid’s flow rate; secondary safety and suction valves; slide valve with flow rate limited to 40 l/min, or 60 l/min for the given work pressure; auto-kickout control, mechanical lever control, draw-bar control, and Bowden hydraulic or pneumatic control; connecting branches: P,T - M27 x 2.0 - G ¾"; A,B - M22 x 1.5 - G½"
