Hydraulic valve 40 l/min (11GPM) for Koyker Loader 125 140 145 150 155 160 165

Single- and double-sided cylinder control.

Slider principle:

Three-position lever on spring, i.e. it returns to vertical by itself.

Neutral position one (lever set to vertical) cylinder piston rod stands - oil goes to overflow.

Working position two (lever angled forward) cylinder piston rod extends.

Third operating position (lever set in diagonal to rear) cylinder piston rod retracts.

Internal threads in the body:

Connection port supply: 1/2''

Connection port return: 1/2''

Connection port sections : 3/8''

Pressure range:

Maximum supply pressure: 250 Bar (3625.94 psi)

Maximum pressure on return: 50 Bar (725.19 psi)

Maximum pressure on sections: 300 Bar (4351.13 psi)

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

180 bar (2610.68 psi) at 10 l/min

190 bar (2755.72 psi) at 20 l/min

200 bar (2900.75 psi) at 30 l/min

210 bar (3045.79 psi) at 40 l/min

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

Self-adjustable, full rotation 30 Bar (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.

Scheme:

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.
