SMC developed the LVN series chemical needle valve to overcome bubble generation when using light liquids.  The LVN valve is manufactured from a lightweight PFA material which is highly compatible with acids, bases and ultra pure water.  Normally installed on top of a filter unit, the LVN needle valve can regulate flow rates between 0 to 12 l/min, and when used in conjunction with SMC's LQ2 hyper PFA fittings, outstanding performance is achieved providing minimal leakage, reduced residual fluid, and high flexural strength.
