VS/AM 65

Description

Direct-operated relief valve, VS/AM 65 by Pietro Fiorentini is a safety device which vents gas when the system pressure exceeds the set value due to temporary events, such as expansion due to rise in gas temperature or downstream pressure shocks caused by sudden changes of flow rate.

Strongly recommended for medium and low pressure gas distribution networks, this device can be used with natural gas and previously filtered non-corrosive gases.
