KOSHT Dart valve for pump-compressor pipes with tubing thread
KOSHT Dart valve for pump-compressor pipes with tubing thread is intended for automatic overlap and pressurization of the drilling instrument tube channel in drilling oil and gas wells, and also in maintenance and emergency works.
TS 3742-003-79560377-2009
Check valve structure allows carrying out maintenance works under field conditions. The valves are produced with the right and left directed coupling thread coils.
