Product Overview

25/929310, also marked as 25-929310 or 25929310, is a threaded cartridge main relief valve mounted on the main multi-way valve block of JCB backhoe loaders. Acting as a safety component for the whole hydraulic system, it sets and regulates the maximum operating pressure. It protects the main hydraulic pump and cylinders from damage caused by hydraulic circuit overpressure during heavy-duty work. This widely used hydraulic spare part fits most classic JCB backhoe loader generations and selected compact construction machines. Multiple cross reference numbers are available for direct replacement when servicing equipment.

Key Specifications

FAQs

Q: What JCB machines does the 25/929310 main relief valve fit?

A: It fits JCB backhoe loaders including 3CX,3DX,4CX,5CX, older models 214,215,217,4C,3CX-2, and special versions 3CXS-PC,4CX444 SUPER,4CN444.

Q: What symptoms point to a faulty main relief valve?

A: Typical signs include weak digging or lifting power, machine struggles under load, abnormal hydraulic noise, system pressure unable to reach standard value, or sudden pressure spikes that risk harming other hydraulic components.

Q: Are these cross numbers interchangeable with 25/929310?

A: Yes. 25/618901,25/222659,334/Y2444 and 25/948906 are equivalent replacements for this main relief valve assembly.

Q: What function does the main relief valve perform on backhoe loaders?

A: It controls the upper limit of hydraulic pressure. Once system pressure exceeds the preset value, the valve opens to release excess pressure, preventing overpressure damage to pumps, cylinders and valve blocks.
