High-pressure valves

PROVALVE forged steel high-pressure valves are the ideal solution for many critical applications (e.g. steam parameters of up to 625 °C and 365bar). Only optimised designs can withstand the fast start-up and shut-down processes required today and the resultant high loads.

For high-pressure chemicals and petrochemicals PROVALVE supplies forged steel high-pressure valves with bolted cover flanges made of multiple special materials.

PROVALVE develops, calculates, machines, assembles and inspects valves based on optimum compliance with the respective operating conditions or the conditions as per ASME.
