Greenhouse Gas Leak Survey you say? Here is a nice place to start – these are over-pressure protection devices on valve bodies that can prevent integrity issues while the valve is closed. Think thermally related (sunshine for instance) pressure increase. It’s been said that these are better suited for liquid applications as the over-pressure potential is much higher with a liquid product when compared to a gas. So if one of these is leaking, talk to your valve people for guidance. Want to know more?
