Autoclave Engineers Medium Pressure Needle Valve with Piston Style Pneumatic Operated Actuator - 20SM

All Parker Autoclave Engineer’s valves are available with diaphragm or piston type actuators. Six sizes of air actuators (light, heavy light, medium, heavy duty or extra heavy, single and double stage) are offered to meet the service requirements of Parker Autoclave Engineer’s Low, Medium and High Pressure valves. Both air-to-open (normally closed) and air-to close (normally open) designs are included in the product line. Optional air to open and close are available upon request. For most Parker Autoclave Engineers valve series there is a choice of two or more actuator designs. This provides the most efficient and economical pneumatic valve operation for any combination of process requirements and available air pressure. Actuators are available for outdoor service. These operators provide corrosion resistant components and prevent the ingress of outside elements.
