For those using CAT Pumps in commercial or industrial applications, the CAT Pumps 34235 Valve Kit is a must-have for ensuring long-lasting performance and preventing costly downtime.
What is the CAT 34235 Valve Kit?

3535
3520
35
203
535
It includes everything you need to replace three valves per kit (two kits are required for a complete pump rebuild). Whether you’re dealing with decreased performance, pressure loss, or leaks, this kit can help restore your pump to like-new condition.
Why Routine Valve Maintenance Matters
Pump valves are critical components in regulating flow and pressure within your pump system. Over time, these valves wear down due to normal use, exposure to chemicals, or contamination in the water. Faulty or worn valves can lead to:
Inefficient performance
Leaking seals
Increased energy use
Unplanned downtime
That’s why routine valve inspection and replacement is recommended as part of any proactive maintenance plan. Using the CAT 34235 Valve Kit ensures your system is operating at peak efficiency with OEM-quality parts designed to meet the demands of high-pressure environments.
What’s Included in the Kit?
Each 34235 Valve Kit includes replacement parts for key valve components identified in CAT’s parts breakdown, including:
Valve assemblies
O-rings
Retainers
Springs
These are all matched to factory specifications and tested for durability and proper sealing under pressure. All components correspond to breakdown positions: 162, 163, 164, 166, 167, 168, 170, 172, and 173.
💡 Pro Tip: You’ll need two kits per pump to replace all six valve positions.
Benefits of Choosing OEM Parts
When it comes to high-performance pump systems, OEM (Original Equipment Manufacturer) parts make all the difference. Here’s why:
Exact fit: No guesswork or compatibility issues.
Longer lifespan: Engineered for the same durability as your original parts.
Reduced risk of failure: OEM parts maintain system integrity.
Faster repairs: All parts are pre-packed and labeled for quick installation.
Aftermarket kits may seem more affordable at first glance, but poor materials or mismatched specs can end up costing far more in the long run.
