Abstract:
A subsea hydraulic system comprises a dual (or dual action) check valve on a port for connection to a remotely operated vehicle (ROV). The check valve provides backpressure to flow in either direction. This keeps hydraulic fluid in the hydraulic system, and seawater out. If flow needs to return to the ROV, it may flow out the port, subject to a selected back pressure.

Claim (Index 3):
The dual-action check valve recited in  claim 2  wherein the first plug has a recess in an end thereof sized and spaced to retain one end of a spring of the first check valve in the first bore sealed by the first plug.
