Meca-Inox PY4CY-LNG Fire Block
For emergency shut-off with gases in their liquid state
Description
The PY4CY emergency shut-off valve has been designed to fulfill most of the safety requirements associated with gasses in their liquid state. Such as liquefied natural gas (LNG). The device is fully autonomous. It does not require any air or power supply. The valve is closed by a fuse in case of fire or by pulling the cable manually. The fuse is a spring under tension (from Kinetrol) closing the ball valve in the event of an emergency.
