This Pneumatic Emergency Brake Valve is a heavy-duty rotary manual control valve used in rail vehicles, locomotives, metro systems, and heavy industrial machinery.
The valve features Japanese labeling and is likely manufactured by leading Japanese railway equipment brands such as Nabtesco or Nippon Signal, known for pneumatic braking systems.
Designed for high reliability, this valve provides manual emergency braking override, ensuring immediate brake application in critical situations.
Identification & Markings
Japanese Label Translations:
•?? (Seij?) – Normal Operation
•????? (Hij?-y? Seid?) – Emergency Brake
Lever Positions:
•ON – Activates braking / system charge
•OFF – Normal operation / release
Pneumatic Port Configuration
The bottom section includes clearly marked air ports:
•P – Pressure supply (Main inlet)
•A & B – Output to brake cylinders
•R – Reservoir / Return / Exhaust
This configuration supports controlled air routing for emergency brake actuation.
Functional Description
This valve operates as a manual emergency brake override system.
When switched to Emergency Mode:
•Main brake pipe pressure is vented
OR
•High-pressure air is redirected directly to brake cylinders
Result:
Immediate brake application
Override of primary controller
Safe stopping during system failure
This makes it essential for railway safety systems.
