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 1):
A dual-action check valve comprising:\n a body having a first blind bore in a first end of the body said first blind bore having a first end open to the first end of the body and a closed, opposing second end within the body and a second blind bore in a second, opposing end of the body said second blind bore having a first end open to the second end of the body and a closed, opposing second end within the body, the second blind bore being substantially parallel to said first blind bore; a first spring-loaded poppet valve in said first blind bore; a second spring loaded poppet valve in said second blind bore; a first cross bore interconnecting the first and second blind bores at a first location and open to a first side of the body thereby forming a first port; a second cross bore interconnecting the first and second blind bores at a second location remote from the first location and open to a second side of the body thereby forming a second port; a first plug sealing the open end of the first blind bore in the first end of the body and securing the first spring-loaded poppet valve in the first blind bore; and, a second plug sealing the open end of the second blind bore in the second end of the body and securing the second spring-loaded poppet valve in the second blind bore.
