GROTH Emergency Pressure Relief Valves
Product Overview
Emergency pressure relief valves are designed to provide emergency relief capacity beyond that furnished by normal operating pressure relief valves. They protect against tank rupture or explosion caused by:
- Excessive internal pressure due to transport pumping or pump in/pump out
- Excessive internal pressure due to explosive or fire conditions
The ERV relieves excessive pressure build up, then reseats when pressure has dissipated.
