Abstract
A relief valve having blow down values of 5% or lower is disclosed. The low blow down values are the result of reducing friction within the relief valve. The relief valve includes a movable plunger. Clearance is provided whereby the plunger does not experience significant friction as it moves into sealing contact with the seal assembly. An energized seal assembly forms a tight seal against the plunger while creating little friction, as the seal is elastomeric and the point of contact is minimized. The relief valve further includes an outlet port, which is adjustable 360° about the relief valve.
