ProVia Dual Chamber Spring Brake Chamber Failsafe Auto Emergency Braking ECE R13 Compliant for Heavy Duty Truck

ProVia Dual Chamber Spring Brake Chamber with Failsafe Emergency Braking

The ProVia dual chamber spring brake chamber is engineered for heavy duty truck and trailer applications, providing failsafe automatic emergency braking when air pressure is lost. ECE R13 compliant, this spring brake actuator combines a service brake diaphragm chamber with a powerful spring brake parking chamber, ensuring maximum safety and reliability under all operating conditions.

Key Features

• Dual Chamber Design: Integrated service brake diaphragm chamber and spring brake parking chamber in one compact unit, delivering both normal service braking and emergency/parking brake functions.
• Failsafe Auto Brake on Air Loss: Powerful compression spring automatically engages full parking brake force when system air pressure drops below safe levels, preventing runaway vehicle scenarios.
• ECE R13 Compliant: Certified to UN ECE Regulation 13 standards for heavy vehicle braking systems, meeting international safety and performance requirements for global markets.
• Reliable Emergency Braking: Spring-actuated emergency brake provides consistent and predictable braking performance, even after repeated emergency applications.
• Heavy Duty Construction: High-strength steel housing with corrosion-resistant coating ensures long service life in harsh operating environments including mining, construction, and long-haul transport.
• High Braking Force: Delivers up to 12000N parking brake force and 10000N service brake force, suitable for heavy commercial vehicles and trailers.
