With Direct Acting Solenoid Control
Series 16 valves are direct acting solenoid valves of small size and high reliability. They are suitable for use either with or without air
line lubrication. Valves are available for 1/8 and 1/4 port sizes in three valve types: 3/2 normally open or closed and 4/2. Models are
available for either inline mounting or manifold mounting.
