Claim 15:
16. A regulator to regulate hydraulic pressure of hydraulic fluid for an actuator of a gate valve of a subsea control module in a subsea environment, the regulator comprising:
a housing having a supply and an outlet, the housing defining an interior communicating with the supply and the outlet;
a container movably disposed in the interior in response to the hydraulic pressure in the interior;
a seal arrangement disposed on the container and being movable with the container relative to the supply and the outlet, the seal arrangement being configured to reduce the hydraulic pressure of the hydraulic fluid communicated from the supply to the outlet, the seal arrangement being configured to prevent communication of the hydraulic pressure on the outlet to the supply; and
a check valve disposed in communication between the supply and the outlet, the check valve being configured to permit at least a portion of the hydraulic pressure at the outlet to bypass the seal arrangement from the outlet to the supply.
