Collection:Pneumatic Stem Actuated Valves

View Tameson's range of pneumatic stem actuated valves. Machine automation systems use pneumatic stem valves to detect the position of parts mechanically. The linear motion of a moving part operates the valve by pushing against the plunger. Pneumatic stem valves are often used to sense end strokes of cylinders or doors. Pneumatic stem valves sense moving machine parts and can be used to detect the correct placement of components before machine operation.
