Bendix K021563 SR-7 Spring Brake Modulating Valve – 3/8" PTC
The Bendix K021563 SR-7 Spring Brake Modulating Valve is a heavy-duty pneumatic braking component designed to provide reliable spring brake control in commercial vehicles equipped with dual air brake systems. This valve helps manage parking brake operation, emergency braking and controlled spring brake application when service brake system pressure is compromised.
The SR-7 valve works with the vehicle's spring brake actuators to provide rapid parking brake application and controlled braking during certain air system failures. Its modulating function helps regulate spring brake force in response to service brake control pressure, improving vehicle braking control during emergency conditions.
Designed with an anti-compounding function, the Bendix K021563 helps prevent simultaneous service brake and spring brake forces from placing excessive stress on the brake actuators and related components.
This configuration features straight 3/8-inch push-to-connect control and balance port fittings, a 1/2-inch NPT supply port and four 3/8-inch NPT delivery ports. Its durable construction provides dependable performance in demanding commercial truck environments.
