MEC Emergency Shutoff Valves for Bulk Plants feature a powder-coated ductile iron body with cast hexagonal ends for maximum durability and ease of installation, an integral swing-away check valve with soft seat to promote maximum product flow and minimize product loss in the event of a line failure, and all stainless steel internal component construction provides maximum corrosion resistance. UL listed for use with LP Gas and Anhydrous Ammonia – 400 PSI WOG

Excelerator Railcar ESVs are designed to provide rapid and positive shutdown of gas lines should a downstream rupture or piping break occur during product transfer. They feature a built-in fusible element at the valve opening hub to ensure the ESV will automatically close when exposed to heat between 212°F and 250°F. Additionally, the Excelerator railcar ESVs are equipped with a poppet design similar to the MEC internal safety valves that provides an integral excess flow feature.
