2020-05-11 · Presently, butterfly valves can be found in almost every chemical plant handling a variety of diverse fluids. Butterfly Valve Working Principle. A Butterfly Valve is from a family of valves called Quarter-Turn Valves. Butterfly valves have a relatively simple construction. The main components of a butterfly valve are the body, disc, stem and seat.

1. Butterfly valves have lower valve recovery coefficients, Km, than globe valves. The value of Km relates to cavitation potential. Large values are desirable. 2. Butterfly valves have a greater potential for water hammer than globe valves.

Butterfly Valves Outstanding throttling accuracy for process control is achieved through low-friction, erosion resistant sealing surfaces with very low operating torques. A broad range of applications can be met via metal- and soft-seated designs as well as lined versions for corrosive and hygienic applications.

They are operated with a simple 90 degree turn (qurter-turn) of a disc shaped obstructor. A butterfly valve is a shut-off valve with a relatively simple construction. In closed position, the disc blocks the valve bore while in open position, the disc is turned to allow flow. A quarter turn takes the valve from fully open to fully closed position, or opposite, and thus the butterfly valve allows for quick opening and closure.
