Juuko 800 radio remote controller hydraulic valve 4 spool 80 l/min 12VDC

All three-position sliders on a spring, i.e. they return to the neutral position by themselves when the power supply is cut off.

Slider principle:

Position 1 neutral (power supply cut off) cylinder piston rod stalls - oil goes to overflow.

Position 2 operational (power supply to solenoid one only) cylinder piston rod extends.

Position 3 operating (power supply to solenoid two only) cylinder piston rod retracts.

Internal threads in the body:

Connection port supply: 1/2''

Connection port return: 3/4''

Connection port sections: 1/2''

Pressure range:

Maximum supply pressure: 250Bar (3625,94 psi)

Maximum pressure on return: 50Bar (725,19 psi)

Maximum pressure on sections: 300Bar (4351,13 psi)

The opening pressure of the bypass valve increases proportionally with increasing flow rate:

180 bar (2610,68 psi) at 20 l/min

190 bar (2755,72 psi) at 40 l/min

200 bar (2900,75 psi) at 60 l/min

210 bar (3045,79 psi) at 80 l/min

It is recommended to check and set the correct pressure before commissioning.

Self-adjustable, full rotation 30Bar (435,11 psi change).

Temperature range and oil type: 

Permissible ambient temperature: -40 C to +60 C

Permissible oil temperature: -15 C to +80 C

Recommended hydraulic oil on mineral oil basis, e.g. HL 32 or HL 46

Recommended oil filtration of 10 - 15 µ

Open centre system (pump-to-tank flow)

Modification / Spools with 1 to 7

HIGH QUALITY Made in EU

The hydraulic valve is widely used in hydraulic systems in construction, industry and agriculture.

The valve is adapted to various types of machines such as: 

sprayers, turners, cyclops, HDS loaders, construction machines, loaders, excavators, sweepers, agricultural machines, tractors, industrial machines and other hydraulically operated equipment.

Can be used with MF, CASE, Caterpillar, Komatsu, Volvo, JCB, Liebherr, Hyundai, Bobcat, Kawasaki, John Deere..... and many more.

K800 8 Push Button single speed.

Independent LED’s,indicate the status of the battery.

Switching power system.

Activation of the transmitter is protected by an electronic key-code and an auto shut-off option which is programmable.

The system automatically change to a another frequency in the presence of radio interference.

Eco power management system. Save on batteries.

It can receive and display via LED 1 and LED 2, signals coming from the machine control system (relay action feedback).

Mushrooms type EMO button.

Wireless pairing procedure using the keyboard pushbuttons.

The Powerbeyond sleeve is a device that allows an additional manifold to be connected by using a pressure transfer port.

This solution provides power to another valve from a normally closed port allowing high pressure to be transmitted.

To use this function, it is necessary to remove the plug from the pressure transfer port and screw the pressure transfer sleeve in place.
