Butterfly valve 1181 series

leverfor gaslug type

The 1181 series lug butterfly valve is engineered with extended neck dimension for special isolation purposes. It utilizes ISO 5211 mounting pad, and ISO PN 10/16 flange designs. This assembly is integrated with complete crossing stem, and a detachable nitrile butadiene rubber gas seat. It is a reliable mechanical solution, considering its compliance to NF ROBGAZ standards. A lever fitting is employed with a locking scheme that allows 9 distinct alignment.
