Product Introduction: Minimum Pressure Valve Maintenance Kit
1. What is a Minimum Pressure Valve Maintenance Kit?
A Minimum Pressure Valve Maintenance Kit is a comprehensive set of
high-quality OEM (Original Equipment Manufacturer) or
OEM-equivalent replacement components designed specifically for the
overhaul, repair, and preventive maintenance of a Minimum Pressure
Valve (MPV).
This all-in-one kit contains the critical wear parts and seals that
are most susceptible to degradation over time, enabling a complete
valve rebuild that restores it to like-new performance, ensuring
system reliability and avoiding costly unplanned downtime.
2. The Purpose & Necessity: Why You Need This Kit
Minimum Pressure Valves are critical for system safety and
performance. Over time, their internal components wear out due to:
High-Pressure Cycling: Constant opening and closing leads to wear on the poppet and seat.
Contamination: Fine particles in the hydraulic fluid can score surfaces and
abrade seals.
Seal Degradation: Elastomer seals can harden, crack, or shrink due to age, heat, and
chemical incompatibility.
Symptoms that indicate you need a maintenance kit include:
Failure to Hold Pressure: Drifting loads or pressure drop indicating internal leakage.
Slow System Response: Valve sticking open or closed due to worn parts.
Visible External Leaks: From around the adjustment screw or body seals.
Using a dedicated maintenance kit ensures a correct, reliable
repair with parts engineered to work perfectly together, restoring
the valve's precise cracking pressure and sealing integrity.
3. Kit Contents: What’s Inside?
Our maintenance kits are meticulously curated to include every
essential component for a full rebuild. A typical kit includes:
Poppet Assembly: The core sealing element. Precision-machined and lapped to match
the original specifications.
Seat Ring/Sleeve: The hardened mating surface for the poppet. Critical for a
leak-tight seal.
Spring(s): The component that determines the cracking pressure. Manufactured
to exact load and rate specifications to ensure pressure setting
accuracy.
O-Rings & Seals: A full set of high-quality elastomer seals (e.g., NBR, Viton,
Polyurethane) for all ports, caps, and spools. Resistant to
standard hydraulic fluids and temperatures.
Back-up Washers & Wear Rings: To prevent extrusion and guide moving parts.
Thread Locking Fluid / Sealant: A small tube for securing adjustment screws during reassembly.
Detailed Instructions: Step-by-step, illustrated rebuild guide with torque specifications
and safety warnings.

5. Applications & Compatibility
This maintenance kit is designed for use with:
Brand: [e.g., Your Company's Name, Bosch Rexroth, Parker, Eaton-Vickers,
etc.]
Valve Models: [e.g., Specifc model numbers like MPV-10, R4V, etc.]
Common Equipment: Ideal for maintaining MPVs in excavators, loaders, presses,
injection molding machines, and other hydraulic machinery.
(Note: It is crucial to select the kit that corresponds exactly to
your valve's model and serial number.)
6. How to Use This Kit
Isolate and Depressurize the hydraulic system completely.
Remove the Minimum Pressure Valve from the manifold or pump.
Disassemble the valve carefully, noting the order of components.
Clean all non-replaceable metal components thoroughly.
Replace all old parts with the new components from the kit.
Reassemble using the provided instructions and specified torque values.
Reinstall the rebuilt valve and test the system for leaks and proper
pressure setting.
