309-5795 3095795 Travel Valve Pressure Sensor for Caterpillar CAT C13 Engine

Tip: Specs can vary by revision/supplier. Please confirm by part number + machine serial number before ordering.

Overview

The 309-5795 travel valve pressure sensor (pressure switch) is designed to detect hydraulic pressure in the travel valve and support stable travel control. It is commonly referenced in Caterpillar parts listings as a Travel Valve Pressure Switch.

Key Features

• Designed for travel valve pressure detection to support consistent machine movement

• 12–32V DC operating range for common heavy equipment electrical systems

• 7/16-20 UNF external thread for correct mounting/port fitment

• Alloy brass body material for durability in harsh environments

• Suitable for maintenance shops, fleets, and distributors (MOQ 1, bulk supply available)

Cross Reference (Common Catalog Numbers)

If you need more cross numbers, send your engine plate + machine model.

Fitment Reference (Models commonly listed)

According to public Cat parts listings, 309-5795 appears on multiple equipment types (example: certain excavator models and generator sets). Always verify by part number and serial number.

Typical Symptoms of a Faulty Travel Valve Pressure Switch

Intermittent travel issues (travel response inconsistent, especially under load)Travel-related warnings/faults on monitor (model-dependent)Oil leakage around the sensor port (seal/torque issue)

Quick Field Checks (Before Replacing)

Visual check: connector pins, corrosion, oil contamination, harness chafing near the travel valve areaElectrical check: confirm supply voltage and ground integrity (machine-specific wiring)Swap/Isolation idea: if you have identical sensors on the machine, swapping can help determine if the fault follows the sensor (only when safe and appropriate)

Installation Notes (Best Practice)

Clean the port and sealing surface; replace the sealing ring if requiredTighten to the OEM-recommended torque (model-specific)After installation: run a short travel test and re-check for leaks
