Gas Isolation Butterfly Valves
The gas isolation valves are a wafer pattern butterfly valve that are PN16 lugged and have a nitrile rubber liner suitable for natural gas.
The valves are sandwiched between two PN16 flanges and are manually operated via a lever.
The lever operates the stainless steel disc in the middle of the valve which closes against the nitrile rubber making a tight seal.
