A check valve assembly for use with a liquid jet cutting system can include a check valve body a high-pressure fluid inlet on one end and a high-pressure fluid outlet on the other end along a central axis of the check valve body. The check valve body can have a first metallic seal surface on an outer surface of the check valve shaped to engage an endcap of the liquid jet cutting system to form a first seal. The assembly can include an annular low-pressure fluid chamber surrounding a portion of the check valve body and defined at least in part by an annular gasket, the check valve body, the first seal, and the endcap. The check valve body can include a low-pressure fluid channel, and a check valve positioned between the low-pressure fluid channel and a high-pressure fluid chamber.
