Pressure Regulation Valve ULH 250-K

Precise pressure regulation in the working system depends on the condition of the valve, which is responsible for controlling operating parameters and ensuring the correct response of the installation to load changes. In the complete ULH 250-K version, this element is a ready-to-install subassembly intended for mounting in the location предусмотрено by the device design.

APPLICATION

The pressure regulation valve is used in repairs and service work on equipment where it is necessary to maintain the correct working pressure level and stable operation of the hydraulic system. This type of part operates in the area responsible for controlling flow parameters and the system’s response to changes in settings.

In service practice, replacement of the complete valve is justified when regulation no longer works smoothly, the system responds with delay, or problems occur in maintaining the set parameters. The use of a complete component is also important in repairs where wear affects not just one small detail, but the entire assembly responsible for pressure regulation.

SYMPTOMS - WHEN IT IS WORTH REPLACING

• working pressure changes unstably despite correct operation of the other subassemblies
• regulation works with resistance, in steps, or does not provide full control over operating parameters
• the valve does not maintain the set settings
• signs of wear, leakage, or mechanical damage appear in the assembly area
• after disassembly, it turns out that wear affects more than just a single valve component

HOW TO CHOOSE THE CORRECT COMPONENT

When selecting a pressure regulation valve, attention should be paid not only to the type of subassembly itself, but also to the installation details. In this case, the ULH 250-K designation, reference number 14141K, and 3/8" thread are important. Since this is a complete set, it is also worth comparing the design of the entire assembly with the removed part.

Before installation, the following should be checked:

• compatibility of the designation and part reference
• type and size of the 3/8" connection
• connection layout and valve design
• method of seating at the specific mounting point
• compatibility of the complete assembly with the previously used part

Accurate matching is very important, because regulating valves must work with the system in the way intended by the design. Differences in thread, connection geometry, or assembly design may make installation difficult or disrupt regulation performance.

COMPATIBILITY

The compatibility of this valve should be assessed on the basis of the technical data assigned to the ULH 250-K system and the 3/8" connection parameters. Verification should cover both the connection side and the functional compatibility of the complete assembly with the given pressure regulation system. For parts of this type, visual similarity alone is not enough, because even similar valves may operate differently, have a different connection configuration, or offer a different range of cooperation with the rest of the assembly.

[faq]

Is this valve sold as a complete assembly?|Yes, it is a complete set. This means that the part is intended as a full subassembly for installation, not as a single small repair component.

Why is the 3/8" thread important when selecting the valve?|It is one of the key installation parameters. The connection size must match the mounting point in the system, otherwise the valve will not fit mechanically or will not provide a correct connection.

How can I tell that the problem is specifically with the pressure regulation valve?|Typical symptoms include unstable pressure, difficulty setting parameters, lack of smooth system response to adjustment, or loss of control over the set values despite the proper condition of other parts.

When the regulator is damaged, is it better to replace the whole assembly rather than individual elements?|In many cases, yes, especially when wear affects several cooperating parts or when it is unclear which detail is responsible for improper operation. A complete valve simplifies the repair and helps restore the original configuration of the assembly.

Can the valve be selected based only on similar appearance?|No. For parts responsible for pressure regulation, it is necessary to confirm the designation, reference number, thread, valve design, and compatibility with the specific system. External appearance alone does not guarantee correct fitment.
