CV Series Check Valves Offer
Low Pressure Drop and High Flow
Parker’s CV Series check valves are a rugged built and
versatile product designed to protect hydraulic systems from
fluid back pressure. The CV Series compliments the DT
Series by adding the feature of modular design. The larger
body results in less pressure drop and increased perform-
ance. The CV Series are in-line unidirectional valves, available
in sizes 1/4” to 1”, with a pressure rating of up to 3000 PSI,
and flow capacities to 100 GPM. Standard spring crack
pressures are 5 and 65 PSI. Other crack pressures available
upon request.

3. Valve seats resist damage from shocks,
surges and contamination.
4. Poppet has an oil retention groove
that lubricates the bore and eliminates galling.

minimizing turbulence.
6. Poppet is heat treated to help prevent damage
from shocks, surges and galling.
7. Close tolerance fit between poppet and poppet retainer
creates a cushion that protects valve from surge shock damage.
