Orion CV Conventional Check Valve

Orion CV Conventional Check Valve are available in 1.0” and 1.5” diameter. The Check Valve is installed externally on conventional mandrel. Check dart prevents gas and fluid flow from the tubing back into the casing annulus. An elastomeric check pad is first contacted by the check dart and as differential pressure increases, a metal-to-metal contact acts as a secondary seal. The check valve is manufactured from premium material for corrosion resistance in wells with high concentrations of H2S and/or CO2.
