The SMC VHK3-12F-12FL finger valve delivers manual on-off control of compressed air through a rotating knob that operates with light finger pressure. It uses 12 mm push-in fittings—one straight and one elbow—for direct connection to tubing and is rated for the 2.0 to 17.5 mm size range. This three-port configuration suits pneumatic circuits that require frequent, tool-free flow adjustment at individual stations or test points.
