Product Description

PSL Control valve Block

3 series of electric proportional multi-way Valve is widely used in concrete boom pump truck, crane truck and Other various types of vehicles and equipments which need remote control and proportion handle operation. Our company has the Valves similar as world-famous brand valves. This kind of valve is our company main product. All of the customers are welcome to consult, if you have the special requirement.

Working pressure: Pmax.=420bar(6000psi)

flow: Qmax=100L/min(32g/min) Qmin=3L/min

Voltage: 12V DC ;24V DC

Intended applications: construction machinery, lifting machinery, municipal vehicles, special vehicles, mining machinery, coal mining machinery, petroleum machinery, drilling equipment and so on.

Connection block

Oil-taking way of multi-way valve is equipped with pressure oil inlet P and oil return tank port R, as well as control port LS and measurement ports Z & M.

In compliance with the variety of oil source, constant displacement pump and variable displacement pump

In compliance with the specifications of connecting threads of port P and port R, G1/2, G3/4 & G1

With or without pilot controlled oil supply

With or without pressure limitation

With or without electromagnetic unloading of the pump

Directional spool valve

Proportional directional valve shall be fixed between connection block and end plate by three screw stems (pull rods) and 12 directional spool valves can be mounted for a valve bank at most. Generally, the number of ways of the directional spool valve doesn’t exceed 8. In case the number is equal to or larger than 9, it’s suggested to divide the valves into two valve banks of multi-way valve. As to the directional spool valve with 9 or more ways, in case the system can’t be divided into two valve banks of multi-way valve, it’s required to order corresponding enhanced-type pull rod accessory.

In accordance with the size of working port of directional spool valve AB, G1/2 & G3/4

In accordance with the neutral-position function and flow of directional spool valve

With or without secondary pressure limitation, N no pressure limitation, C-type pressure limitation and AB-type pressure limitation

In accordance with the operation manner, pure manual control, electronic control, hydraulic control & friction positioning

With or without any auxiliary function


End plate

As the terminal of combined-type multi-way valve, the end plate shall be selected according to the characteristics as follows: with oil return port T controlling the internal discharge or external discharge of oil, with or without additional LS, oil inlet P, oil return port R, etc.

l With port T for pilot control of internal discharge or external discharge of return oil

With or without additional LS inlet or cut-off of pump’s circulation loop
