If the pressure switch fails and the motor doesn't stop, the pressure keeps rising inside the tank. The safety valve is what prevents an accident: it releases the air as soon as the pressure exceeds its limit. It is an essential safety component on any compressor.
This threaded safety valve is compact and robust, with a 1/4" or 3/8" thread for up to 11 bar, or 3/8" 14 bar for higher-pressure units. Replace it if yours releases air at normal pressure, is seized or has been tampered with.
No compressor should run with a doubtful safety valve: it is an inexpensive part that protects the tank, the installation and the people working nearby.
✅ Key benefits
Overpressure protection: releases the air if the pressure switch fails.
Three versions: 1/4" 11 bar, 3/8" 11 bar and 3/8" 14 bar.
Compact and robust: designed for workshop and industrial compressors.
Test ring: lets you check it isn't seized.
Essential safety: protects tank, equipment and people.
🏗️ What it's for
Replacing the tank safety valve.
Repairing valves that leak air or are seized.
11 bar workshop compressors.
14 bar high-pressure compressors.
📋 Technical specifications
Models: 1/4" up to 11 bar · 3/8" up to 11 bar · 3/8" 14 bar
Function: overpressure protection
Installation: threaded into the tank
💡 Vetonek tip: always replace it with one of the same thread and pressure as the original (check the compressor's rating plate) and pull the ring from time to time to check it isn't seized. Never replace it with a plug.
Frequently asked questions
What pressure should I choose?
The same as your compressor's original valve, never a higher-pressure one.
Why is my valve leaking air?
If it releases air at normal pressure it may be dirty or damaged: it needs replacing.
What threads are available?
1/4" and 3/8" for up to 11 bar, and 3/8" for 14 bar.
How do I check that it works?
With the compressor under pressure, pull the ring briefly: it should release air and close again when you let go.
Can I run without a safety valve?
No, never: it is the component that prevents dangerous overpressure in the tank.
