DSIV-4000 Downhole Chemical Injection Check Valve



Download Spec Sheet

The DSIV-4000 valve is designed to provide a cost-effective solution for injection valve entry into restricted spaces. While the O.D. of this valve is only .540”, it is capable of holding up to 1500 psi. back pressure. This device functions as a high pressure spring loaded check valve, thus greatly 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.
