Atos ATOS stacking valve HMP-014/350 22spot
Atos anal
Application of Italian ATOS overlay valve:
Stacking valves are suitable for various industrial hydraulic systems, such as injection molding machine hydraulic systems, CNC machine tool hydraulic systems, and metallurgical equipment hydraulic systems. The diameter of the stacked valve comes in various specifications such as 6MM, 10MM, 16MM, 20MM, and 32MM, which are the same as traditional plate hydraulic valves and suitable for different flow working environments.
Types of stacked valves:
Stacking valves can be divided into several types such as directional control valves, pressure control valves, and flow control valves, but stacking valves do not have directional valve function. The assembly requirements for stacked valves are generally the same as those for traditional plate type one-way valves.
ATOS overlay valve HMP-014/350 22
HMP, HM, KM type stacked relief valve
ISO 4401 standard, 06 and 10 diameters
HMP is a direct acting relief valve.
HMP and KHM are two-stage balanced spool type 1 relief valves.

Method of pressure adjustment: Loosen the locking nut ②, rotate the adjusting rod ③ under the protective cap ①, and use the handwheel ⑤ to adjust instead of the valve stem. The pressure can be increased as required.
Rotate clockwise to increase pressure.

Specifications and flow rate:
HMP=06 diameter, flow rate: 35 l/min
KHM = 10 通径,流量: 60 l/min
KM=10 diameter, flow rate: 120 l/min
Installation interface: ISO 4401 standard, 06 and 10 diameters
Pressure: up to 350 bar
ATOS overlay valve HMP-014/350 22 is a commonly used hydraulic overlay valve product under the ATOS brand. The following is a summary of the core information to help you quickly understand its key properties:
1. Brand background
ATOS is an Italian hydraulic component manufacturer, specializing in high-pressure, high-precision proportional valves, superposition valves, directional valves and other products, widely used in industrial hydraulics, engineering machinery, automated production lines and other fields.
2. Interpretation of Model Parameters
The core parameters of this model can be broken down into three parts, accurately corresponding to the product specifications:
-HMP: represents the product series, and the Atos HMP series is a stacked pressure control valve (focusing on overflow, pressure reduction, or pressure regulation functions, which need to be confirmed based on operating conditions);
-014: It is a diameter specification corresponding to the conventional 14 diameter of hydraulic valves, suitable for the flow requirements of medium and high pressure hydraulic systems;
-350: Refers to the rated working pressure, measured in bar (1 bar ≈ 0.1 MPa), which means the valve can withstand a system pressure of 350 bar (35 MPa) and belongs to the high-pressure class valve;
-22: It is an additional specification code from the original factory of Atos, usually corresponding to details such as valve core type, adjustment method, sealing material, or voltage adaptation. The specific specifications should be based on the Atos product manual.
3. Core purpose
As a stacking valve, it can be directly stacked on hydraulic manifold blocks or directional valves without additional installation space, mainly used for:
-Accurately adjust the working pressure of the hydraulic system;
-Prevent system overload and provide safety protection;
-Adapt to industrial hydraulic scenarios with medium high pressure and medium flow rates, such as machine tools, injection molding machines, metallurgical equipment, etc.
