Check valves are uni-directional valves which automatically
open with forward flow and close against reverse flow.
They are supplied to meet a wide variety of applications
with the closing element in the piston, ball or swing type.
Piston check valves are normally supplied by Diantai with
the addition of a spring which allows both the vertical
and horizontal installation.
Great care is given by Diantai employees in the design
and in manufacturing to prevent noisy operation and
unsatisfactory wear of closure components.
The full range of Diantai production is reported on pages
37 to 42.
