Features

Download Case Study

Pilot operation ensures accurate pressure and vacuum relief.
Choice of body materials.
Fully open at 10% overpressure, enabling setting close to MAWP/MAWV and minimizing tank emissions.
Leakage rate of 0.5 scfh (0.015 Nm3 /hr) or less at 90% of setpoint.
Modular design enables all components to be removed and replaced in-situ for quicker, simpler maintenance.
Optional ‘all-weather’ coating prevents frozen condensate build-up and sticking of vital components in cold weather applications.
