Regulate the flow of air and pressure in your pneumatic control system with this bistable pneumatic manual control valve from Festo. It lets you control the direction of flow through tubes to ensure the smooth functioning of equipment. You can also use it for pressure relief by diverting or releasing excess air pressure to prevent damage and downtimes that interrupt production. This unit has three ports and two positions and can be fitted with cylinders or pneumatic actuators.

• Non-reversible flow direction establishes one-directional flow and prevents potentially damaging backflow
• Piston slide reduces resistance to airflow and improves the efficiency of pneumatic systems
• Die-cast aluminium housing offers resistance to corrosion, so is durable and suitable for use in fluid-based systems

• Industrial equipment actuators
• Compressed-air pumps
• Pilots for other valves
• Food and beverage industry

No, a pneumatic control valve restricts flow in one direction while allowing free flow in the opposite direction. Needle valves restrict flow in both directions and effectively cut off air or fluid flows.
