Check valve, ball type (KOSh)
Tight check valve, ball type, KOSh(P)
It is designed for the passage of working fluid (drilling mud, water, reservoir fluid) in one direction. It closes the channel when the pressure drops from the working fluid feed side during process operations, automatically prevents the reverse flow of liquid and keeps the liquid in the tubing string after the pump stops. Other types of valves can also be supplied at the request of the customer.
Tight check valve, ball type, KOSh-P-V
It is used with a pump injecting liquid into the below-packer space. The valve ensures that the channel is blocked after the pump stops and prevents the backflow of liquid.
