CAT Excavator Pressure Switch Excavator Idle Distribution Valve Pressure Sensor for CAT312 CAT320B/C/D
Product Overview
This is a dedicated hydraulic pressure switch (pressure sensor) for CAT excavators, one of the core accessories of the excavator hydraulic control system. It is compatible with mainstream CAT excavator models, used for pressure monitoring and signal feedback of the hydraulic system, and can directly replace the original parts to solve problems such as weak equipment movement, unstable idling, and fault alarms.
Core Functions
Real-time monitoring of hydraulic system pressure changes, converting pressure signals into electrical signals and feeding them back to the on-board computer (ECU)
Controls automatic idling, travel/swing action response, and optimizes equipment power output
Triggers fault alarms when pressure is abnormal, protecting key components such as hydraulic pumps and distribution valves
Multi-specification plug adaptation, covering interface requirements of different CAT excavator models
Product Specifications
Brass connector + high-strength insulating housing, high pressure resistant, corrosion resistant, oil and water proof
High-precision pressure sensing element with stable signal and fast response
4 common plug types available:
Large Square Plug
Small Square Plug
Small Round Plug
Large Round Plug
Vibration-resistant design, suitable for complex construction site conditions, long service life
Application Scenarios
Repair of hydraulic system pressure faults on excavators (e.g., weak movement, slow speed, automatic idling failure)
Pressure signal feedback for distribution valves and main pumps to restore normal equipment control logic
Replacement of foreign trade construction machinery accessories, suitable for the overseas CAT excavator maintenance market
Purchase Highlights
一. Wide Compatibility for Mainstream Models
Compatible with almost all mainstream CAT excavator models including 307/312/320B/320C/320D, covering all pressure detection points such as hydraulic distribution valves, travel/swing motors, and idle control systems.
Equipped with 4 common plug specifications (Large Square/Small Square/Small Round/Large Round), allowing direct replacement of original parts without modification, greatly reducing installation and after-sales communication costs for customers.
二. Reliable Quality, OEM-Equivalent Performance
Constructed with high-pressure brass connectors and industrial-grade waterproof/oil-resistant housings, the sensor is vibration-resistant and corrosion-resistant, perfectly adapting to harsh construction site conditions with service life close to OEM parts.
