  • (2) Plate (Flapper)
    Flapper type sight glasses are used for observing the state of fluid flow depending on opening and closing of the flapper on fluid flow.
Q2:  What kind of glasses is available?
A2:

(1) Tempered Glass: Max. Temperature 80°C
(2) Pyrex Tempered Glass: Max. Temperature 260°C
