Description

The Wabco 9710020200 Relay Emergency Valve is a critical component in air brake systems, designed to rapidly shut off air supply in emergency situations, ensuring vehicle safety. It is typically used in commercial vehicles, buses, and trucks. This valve features a robust design with M22 x 1.5 and M16 x 1.5 port threads, and is configured as an emergency-only valve with a 0.7 bar adjustment range and maximum operating pressure of 10.0 bar. Its dimensions are 122 x 110 x 169 mm. This relay valve provides a reliable and responsive emergency braking function, enhancing overall vehicle control and minimizing potential hazards.

Key Features & Benefits

This valve basically does what it sounds like – it cuts off the air supply to the brakes in an emergency situation. Specifically, it’s triggered by a sudden, significant air pressure loss – like if you spring a leak in your air lines or have a really serious failure in the air compressor. It’s a fast – acting valve, so it reacts quickly to protect the system. It also has a manual override, so you can shut the system down yourself if needed for maintenance or repairs. Think of this as a critical safety component in your air brake system. It’s there to prevent a runaway situation if you lose air pressure. It's usually installed somewhere in the air supply line, fairly close to the air compressor and before the other components get air. It's part of a chain of things working together to ensure you can always stop.

Symptoms, Risks & Replacements

It’s incredibly important. Without it, a major air leak could mean losing all braking power, which obviously isn’t good. It acts like a shield, preventing a complete brake failure. You’ll notice if this valve fails because your emergency brake application might not hold, or you might see a warning light on your dash. It's a fairly inexpensive part when you consider what it's protecting, and you can find a replacement easily enough at places like Fixparts Online. It’s one of those things you really don't want to skip replacing if it’s showing any signs of trouble.
