| Circulation
pump export the valve
First, the product brief introduction of circulation
pump exports the protection valve that the valve is used for
the unit boiler circulation pump of electricity generation
by thermal power and export, can prevent the medium in the
pipeline system from flowing backwards and damaging the circulation
pump automatically when stopping the pump. This valve also
has a function of stop valves except that there is function
of non-return valves, through operating handwheel which bumps
into the structure, make the valve close tightly . Is the
valve imports and exports contained angle 90? ,If because
user install restriction of space, is it adopt 90 non- to
cost? Imports and exports contained angle (such as 60?) When,our
factory can according to the need of user it supply,and can
guarantee valve increase the obstruction coefficients. Our
factory produces the main producer that 300MW boiler related
circulation pump exported the valve at home, this serial valves
can at the same time be used for substituting and introducing
importing the valve similarly of the aircrew . Second, products
