Diverter, Shut-Off and Blocker Valves
Current and upcoming emission standards have created new challenges in engine and exhaust design. Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems incorporated into the exhaust system have created a need for new specialty components. Diverter, blocker and shut-off valves are used to shut down or divert harmful exhaust gases between exhaust system devices and restrict the exhaust gas flow to increase DPF temperatures for regeneration mode. They also allow Auxiliary Power Units and the main engine to share the same emission compliant exhaust system. All Pacbrake diverter, shut-off or blocker valves can be used in alternative fuel exhaust systems or laboratory set-ups.

Pressure Regulated Warm-Up Valves
Warm-up valves promote rapid engine warm up, ideal for cold weather applications that use any type of diesel engine. - Designed to maintain high temperatures in the engine and exhaust system by sustaining a constant low pressure at variable exhaust gas flow
- Substantial aid in increasing exhaust gas heat retention
- Helps reduce emissions
- Can be used upstream or downstream in the exhaust system
- Prevalent in school bus applications to increase in-cab comfort
- Pneumatic actuated
- Pressure regulated valve with a fail-safe device built in
- Warm-up units can be electronically controlled by stand-alone controller, or by existing ECU; controller can interface with existing ECU via CANBUS
