Vent Valves
Protect the safety of your personnel and tank assets from over/under pressurization that may lead to catastrophic events.
Vent valves provide venting relief per API 2000 and provide superior venting relieving capacity for emergency conditions. Gauge and Thief Hatches offer multiple relief settings and access for tank gauging. Hatch-tight seal technologies prevent leakage and evaporation losses.
FAQs
A Pressure Vacuum Relief Valve (PVRV) is a pressure, and vacuum relief device, typically installed on a storage tank or terminal, but these devices can be used in a number of different applications. These are non-coded, low-pressure devices, that can be easily maintained in the field. They are offered in either weight-loaded or spring-loaded configurations, depending on your process’s pressure and vacuum needs.
Thief hatches are a commonly used venting device for low-pressure storage tanks. They are spring-loaded pressure and vacuum relief devices that can be easily maintained, and pressure settings can be changed by swapping out the hatch springs by hand. Enardo’s newest ES-665 Thief Hatch offers best-in-class leakage rate of 0.1 SCFH @ 90% of set point to ensure the lowest amount of product loss to the environment.
