LVA*A, High Purity Chemical Valve, Air Operated, Integral Fitting, Stacking Type

SMC high purity series LVA valve has three types of body materials (SUS/PPS/PFA) that can be selected based on the customers application. Special diaphragm construction insures gentle opening and closing that prevents the formation of micro-bubbles. A unique guide ring on the piston rod eliminates lateral motion of the poppet, greatly increasing seal life and reducing particle formation.
