Lug type butterfly valves with stainless steel disc.

Lug-type butterfly valve with stainless steel disc. Lug-type butterfly valve with stainless steel disc and threaded holes. Body in ductile iron PN16 and disc in AISI 316 stainless steel. Butterfly valves can be configured with different types of sealing liners depending on the operating temperature and the type of fluid. The sealing liners are available in NBR, EPDM, PTFE (Teflon) or Viton. They are mainly used for shut‑off and regulation of water and gas. Butterfly valves can be operated manually with a lever, or equipped with pneumatic or electric actuators. They consist of a disc-shaped obturator used to open and close the fluid passage, and are typically used when high regulation precision is not required and low pressure drop is desired
