- An complaint often heard in both semiconductor and chemical equipment industries, is that it’s almost impossible to eliminate bubble formation in the fluid circuit during the manufacturing process. Following extensive research and development, engineers from SMC, the worlds leading automation control experts, are pleased to announce that this is no longer the case with the introduction of their latest chemical needle valves – Series LVN.Developed especially to overcome bubble generation when using light liquids, LVN valves are manufactured from a new type of lightweight PFA material which is highly compatible with acids, bases and ultra pure water. Normally installed on top of the filter unit, these needle valves can regulate flow rates between 0 to 12 l/min and when used in conjunction with SMC’s LQ2 hyper PFA fittings, with their unique quadruple seal construction, outstanding performance is achieved providing minimal leakage, reduced residual fluid and high flexural strength.Series LVN valves are the perfect answer when working with fluids between 5 – 90º C, at operating pressures of 0 – 0 ,5 MPa and in ambient temperatures of 0 – 60º C - a champagne solution minus the bubbles.
