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 5):
The dual-action check valve recited in  claim 1  wherein\n the first blind bore in the first end of the body has a first section having a first internal diameter (i.d.), a second section having a second i.d. that is less than the first i.d., and a first inclined shoulder between the first section and the second section, \n the first spring-loaded poppet valve in the first blind bore is sized and configured to seal against the first inclined shoulder, \n the second blind bore in the second end of the body has a first section having a first internal diameter (i.d.), a second section having a second i.d. that is less than the first i.d., and a second inclined shoulder between the first section and the second section, \n the second spring-loaded poppet valve in the second blind bore is sized and configured to seal against the second inclined shoulder, \n the first cross bore interconnects the second section of the first blind bore with the first section of the second blind bore and the first port, and \n the second cross bore interconnects the second section of the second blind bore with the first section of the first blind bore and the second port.
