Main Valve Core:
Introduction:
The tungsten carbide parts for MWD and LWD are mainly used for the function of flushing, slurry sealing, flow diversion, and sending slurry pressure and other information back with pulse signal. The tungsten carbide main valve core is one of them used in MWD and LWD. Different specifications of the main valve core in use can produce different pressure signals, easy to adjust the pressure signal strength according to well conditions, well depth and other factors.
