Piper Valve Systems designs and manufactures compact high pressure valves and manifold system components for all environments of the oil & gas industry including onshore, offshore, and subsea applications. Piper's valve and manifold bores are designed to closely match the inside diameter of the required pipe schedule for the system working pressure. The result is elimination of piping transition areas that minimize erosion and system friction pressure loss, resulting in a more efficient flow path.
