The Festo GGO-1/4-3/8 is a pneumatic pressure relief valve that protects air systems from overpressure. It opens automatically when pressure exceeds the set limit, venting excess air safely. Rated up to 8 bar, it is commonly installed in compressed air lines where pressure control is critical for system safety and component protection. This valve does one job and does it reliably. It is used where pressure spikes can damage equipment or affect performance.
The GGO-1/4-3/8 is designed to fit standard pneumatic setups without modification.
It is often used as a protective measure in systems that operate close to their pressure limits.
