Collection:Pneumatic Stem Actuated Valves

View Tameson's range of pneumatic stem actuated valves. These valves are commonly used in machine automation systems to detect the position of components such as cylinders, doors, or other moving machine parts. A component's linear motion pushes directly against the valve’s plunger (or stem), mechanically activating the valve. Pneumatic stem valves are often used to confirm end-of-stroke positions or verify correct placement before a machine cycle begins.
