Valve & Automation’s control valve, more than four metres tall, produced for Siemens Energy in Duisburg, has broken ARCA’s internal design height record.
In Septembernbsp2021, Valve & Automation ran a special type of acceptance test at one of its factories in Tönisvorst, Germany. With the production of this ‘control giant’ with a design height of 4,20nbspmetres, the company confirmed that it is a leader in control valve design and manufacture, and is a first contact partner in compressor construction.
This record was achieved by the pairing of a 60nbspcm valve with a special bonnet, which in addition to its conventional components, also included a bellows seal, which was specially designed to prevent any emission of the medium through the stuffing box. The enormous design height made it necessary to switch to alternative assembly steps in order to manufacture the valve according to customer requirements.
Together with this colossus, this project from Siemens Energy included a 50nbspcm valve and a 157nbspcm perforated disc. Siemens Energy required these valves for a plant owned by Formosa Petrochemical Group, which will be built in the eastern Chinese coastal city of Ningbo. The control valve was part of a delivery of a gear type turbo compressor train, which is to be used in a purified terephthalic acid plant (PTA) to manufacture plastic products. The compressor train consisted of a gear type compressor of the STC-GVnbsp(200-4) type and a cold gas expander STC-GTnbsp(160-2),driven by an electromotor.
