APPLIATIONS
|
 It is
widely used in the process automation control system in such����� ��industries
as oil,chemical industry,metallurgy,power,and light����� � ��industry,It
has perfect isolating performance for gas and liquid���� � ��conveyer
tube.Therefore,it is best suited for cutting off and������� ��controlling
various liquids,gases,slurries etc. |
| |
FEATURES
|
| When it
is fully opened,the internal diameter of the flow and the pipe��� ��line
are basically the same with limited loss of fluid pressure. |
| ZR SERIES PNEUMATIC O-SHAPED ISOLATING BALL VALVES |
U-shaped
metal free valve seat has good sealing performance,the flow ��� ��is�not
limited, and it is easy to install. |
|
|
Simple
in structure,long in durability,sensitive in motion large in����� ��circulation
and easy in maintenance. |
