DCIV-8000 Downhole Chemical Injection Check Valve


Download Spec Sheet

DCIV-8000 valve is capable of holding up to 3500 psi. back pressure. This device functions as a high pressure spring loaded check valve, thus reducing the possibility of free flowing chemical into the well and back flowing into the tubing string due to changes in well and tubing conditions or pressures. Being a check valve by design, this valve will be affected by well pressures.
