2G-3537: NPTF Port Relay Valve

Description: The primary function of a Relay Valve is to regulate the air pressure in the brake system. It receives air pressure from the main reservoir and delivers it to the brake chambers or other control valves at the appropriate level. This regulation ensures that the brakes engage and release correctly for efficient braking performance. Attributes: • Withstand the operating pressure • Ensure sufficient air supply for effective brake operation Application: The Relay Valve is an important component in pneumatic brake systems across a range of applications, ensuring precise control, synchronization, and reliable operation of brakes in vehicles. It is widely used in Cat 120G, 12G, 130G, 140G, 14G, and 16G Motor Grader, 611, 615, 615C, 621B, 621E, 621S, 623E, 627E, 631C, 631D, 631E, 633D, 633E, 637D, 637E, 639D, 639E, 641B, 651B, 651E, 657B, and 657E Wheel Tractor Scrapers, 611, 615, 615C, 621B, 621E, 623B, 623E, 623E, 623F, 627B, 627E, 631D, 631E, 633D, 633E, 637D, 637E, 639D, 639E, 641, 641B, 651, 651B, 651E, 651F, 657, 657B, 657E, and 657F Scraper, 615C 768C, 769C, 772B, and 773B Truck, 772 Wagon, D400D Articulated Truck, and TH35 Powertrains.
