Description
ELGi B012805340028 Safety Valve for EG30–EG37 Air Compressors
Replacement safety relief valve • EG30–EG37 compatibility
This replacement safety valve is used to protect the compressed air system from overpressure conditions. If system pressure rises above the valve’s set point, the valve opens to relieve excess pressure and then reseats once pressure returns to a safe range.
It is commonly installed on compressor-mounted piping and/or the air receiver as part of standard pressure protection for lubricated rotary screw compressor packages.
Key Features
- Overpressure protection: Automatically vents excess pressure to help protect equipment and personnel.
- OEM-fit replacement: Intended for use with ELGi EG30–EG37 compressor packages where this valve is specified.
- Threaded connection: Designed for a straightforward replacement on compatible ports/fittings.
- System safeguard component: Supports stable operation by providing a mechanical pressure relief backstop.

Frequently Asked Questions
ELGi EG30–EG37 Safety Valve
▶️ Question: What does a safety valve do on an air compressor system?
Answer: It opens automatically if pressure rises above a safe limit, venting air to reduce pressure and help prevent equipment damage or unsafe conditions.
▶️ Question: How do I confirm this valve fits my EG30–EG37 package?
Answer: Match the MPN on your existing valve and confirm the port thread size/type and required set pressure for your compressor/receiver. If the existing valve is missing, match the compressor model and the installed connection details.
▶️ Question: Can I adjust the set pressure on a safety valve?
Answer: No. Safety relief valves should not be adjusted in the field. Use the correct rated replacement valve specified for the system.
▶️ Question: When should a safety valve be replaced?
Answer: Replace it if it leaks continuously, sticks, won’t reseat, shows corrosion/damage, or fails inspection/testing practices used at your site.
▶️ Question: Where is the safety valve typically installed?
Answer: Common locations include the compressor discharge/aftercooler piping and/or the receiver tank, depending on how the package is configured.
