Ringo Válvulas has concluded the design, manufacturing and testing of large cage guided globe control valves for BidBoland Gas Treating Plant II, a new plant that gathers sweet and sour gas from existing fields to produce Ethane (C2), Propane (C3), Butane (C4), and Condensate (C5+) for export.
Valves need to regulate critical pressure drop for big flow rates of residue gas and therefore the process conditions calculated Cv value required large valve sizes of 24” and 20”:
1 off 24” 600# Globe control valve
2 off 20” 300# Globe control Valve
Additionally, valves have been designed and produced with attenuation plates to reduce the outlet velocity and the consequent noise level. Selected trim was designed to provide a good technical and cost effective solution:
a) Multicylinder trim in order to reduce the number of stages needed in the silencer to reduce the weight of the same.
b) Balance trim in order to reduce the valve thrust and, therefore to have a smaller size of actuator as well as a smother performance.
