Wabco 9710023050 Emergency Shutoff Valve

Description

The Wabco 9710023050 Relay Emergency Valve is a critical component in air brake systems, designed to rapidly shut off air supply in emergency situations. This valve is commonly used in commercial vehicles and heavy machinery to ensure driver and passenger safety. Measuring 134 x 167 x 148 mm, it features multiple port connections including M22 x 1.5 JED152 and M16 x 1.5 JED - 152, and operates within a temperature range of -40°C to +80°C. This emergency shutoff valve provides a reliable and responsive safety mechanism, contributing to enhanced braking performance and operational security through its OE specification and precise 1 bar range of adjustment.

Key Features & Benefits

This valve basically controls the air supply to your air brake system when there's a critical loss of air pressure. It’s got a couple of main jobs. First, it automatically applies the spring brakes – those big emergency brakes – if the air pressure drops too low. Think of it like a safety net. Second, it isolates the air tanks, so you don't lose all your air instantly if you spring a leak somewhere. It’s a bit like patching a hole in a tire to keep from going flat immediately. It sits within your air brake system, specifically between your air compressor, reservoirs, and the brake chambers themselves. It’s a key part of the relay valve network. It’s constantly monitoring the air pressure. Normally it allows air to flow freely, providing pressure for regular braking. But the instant it senses a significant pressure drop, it springs into action and initiates the emergency brake application. It acts like a shield, preventing a runaway situation if you lose air pressure while driving.

Symptoms, Risks & Replacements

Honestly, this is a safety component through and through. If this valve fails, you could end up without emergency braking, which, well, you can imagine isn’t a good spot to be in. You’ll notice if it's failing if your emergency brakes engage unexpectedly, or if you have trouble applying them when you need to. They’re crucial for preventing accidents, particularly with heavier vehicles that rely on air brakes. You can find these, and a lot of other air brake components, over at Fixparts Online if you’re doing some maintenance. It’s something you really don’t want to gamble with; regular inspection and replacement when needed is the smart move.
