A valve assembly includes an upper sleeve, a lower sleeve, and a poppet contained between the upper and lower sleeve and operable between a first and second position. The poppet includes a first end, a second end, a side, a central cavity, and a hydraulic port. The second end is spaced from the first end, the side is adjacent one of the first end and the second end. The central cavity extends from the first end of the poppet towards the second end of the poppet. The hydraulic port extends from the side of the poppet into the central cavity. The hydraulic port is configured to receive hydraulic fluid at a first flow rate from the supply port and to supply hydraulic fluid to the central cavity at a second flow rate less than the first flow rate.

Valve assembly

Systems, methods, and apparatuses for a regulator are provided. The regulator includes a reducing valve, an accumulator, an accumulator line, and a regulated line. The reducing valve is operable between a closed position and an open position. The reducing valve includes a first opening inlet configured to receive fluid to bias the reducing valve towards the open position, a first closing inlet configured to receive fluid to bias the reducing valve towards the closed position, and a first spring configured to transmit a first spring force to the reducing valve to bias the reducing valve towards the closed position. The accumulator is configured to store fluid at a first pressure. The accumulator line is configured to receive fluid from the accumulator and to provide the fluid to the first opening inlet at the first pressure. The regulated line is connected to the first closing inlet at a second pressure. The reducing valve transitions from the closed position to the open position when a first force created by the first pressure on the reducing valve is greater than a sum of the first spring force, a first tolerance, and a second force created by the second pressure on the reducing valve.
