HYDRAULIC VALVE 3xP40 + FLOATING

General description:

Manual or mechanical hydraulic valve Р40 are intended for distribution and control of the fluid flow between the hydraulic pump and the consumers (cylinders, hydraulic motors,...).
Hydraulic valves are used for various purposes, in agriculture, industry, construction, etc. for steering:

• single-acting cylinders
• double-acting cylinders
• hydraulic motors
• floating functions (for plow)
• joystick (up-down, left-right)

They are assembled in a block of 1 to 7 levers.

Operation:

All hydraulic valves are equipped with a safety valve. In the neutral position (lever in the middle), the oil circulates through the valve. When moving the lever to one side or the other, the hydraulic valve causes the movement of the cylinder or. rotation of the hydraulic motor in one direction or another. After lowering the lever, it automatically returns to the neutral position, the hydraulic motor or the cylinder stops in the current position and the oil circulates through the valve again. It is possible to use the so-called "closed center" element, which changes the valve so that in the neutral position the oil does not circulate through the valve or such a valve is no longer flowable. When using or when connecting other valves, it is necessary to use the "carry over" link, which enables the supply of oil for other valves.

In the case of valves with a spool for the floating function, this allows the cylinder to flow freely, which means that the cylinder moves freely (or the snowplow adapts to the terrain).

Valves with a spools for single-acting cylinder are intended to be used for a single-acting cylinder. 

Structure:

Р40 is a monoblock distribution valve. It is made of cast iron EN-GJL300. The spools are made of carbon steel and are hard chromed.

Connectors:

The spool is screwed with two M8 bolts.
