Centric Type Butterfly Valve

Application:

The Butterfly valves designed in accordance with IS 13095:1991 (BS 5155) and used for mainly water and oil works purposes. Butterfly valves are commonly used as control valves in applications where the pressure drops required of the valves are relatively low. Butterfly valves can be used in applications as either shutoff valves (on/off service) or as throttling valves (for flow or pressure control). As shutoff valves, butterfly valves offer excellent performance within the range of their pressure rating. Typical uses would include isolation of equipment, fill/drain systems, bypass systems and other like applications where the only criteria for control of the flow/pressure is that it be on or off.
