DOT Push In PMT Cartridges
PMT Cartridges is one of the key modules in the DOT PUSH IN series, designed specifically for pressure regulation, protection, and monitoring in pneumatic systems. This module component is made of high-quality brass, combined with advanced sealing technology and quick plug connection process, aiming to provide high-precision and reliable pressure management solutions for air braking, pneumatic control, and other industrial applications.

Main functions
PMT Cartridges are mainly used for precise control and regulation of pressure fluids in pneumatic systems, while also protecting downstream equipment. Through the built-in precision valve core and sealing structure, it can quickly respond to abnormal pressure fluctuations in the system, achieve automatic adjustment or cut-off, and ensure the safety and stability of system operation.
Application areas
1. Commercial vehicle air brake system (such as trucks, trailers, and buses)
2. Industrial automation pneumatic control circuit
3. Other pneumatic systems that require high pressure control
Structure and Working Principle
Modular design:
PMT Cartridges adopts a modular structure, integrating internal pressure regulation, sealing, and protection functions into one. The module contains precision machined valve core components and regulating springs, which automatically activate the regulating program when the system pressure reaches the set value.
Quick plug interface:
Similar to other products in the DOT PUSH IN series, PMT Cartridges are equipped with standardized Push In interfaces, allowing users to easily insert nylon or other pneumatic tubing and quickly lock it in, without the need for additional tools for installation and replacement.
Working principle:
When the pressure inside the system exceeds the preset limit, the valve core inside the module will quickly respond by changing the internal flow channel or temporarily blocking the airflow to regulate the system pressure and prevent component damage caused by excessive pressure. This process responds quickly and acts accurately, providing security for the entire system.Structure and Working Principle PMT Cartridges adopts a modular structure, integrating internal pressure regulation, sealing, and protection functions into one.
