Screwed into exhaust controls of control valves or drives, this series restrict the air exhaust to control the piston speed of cylinders or rotary drives. This is controlled using the adjustment element. Designed with an integrated silencer, these valves reduce noise levels for user comfort. With nickel-plated brass screw and thread these connectors are able to reach a 10bar operating pressure. VFFK series feature connections of M5, M7, R1/8 and R1/4.

• Flow rate of up to 420 l/min
• Knurled screw adjusting element
• Lubricated operation possible
• Nickel-plated brass

This pneumatic silencer and exhaust restrictor function fitting from Festo lets you control flow, rotary drive and piston functions in your pneumatic network. Its in-line connection method lets you attach it directly to your system with minimal loss of air or pressure. An integrated silencer reduces noise levels when your pneumatic system expels air, so you can trust it won’t disturb people working nearby. As the exhaust valve supports flow rates anywhere between 0 and 270 litres per minute, it’s a versatile option for applications including critical quality control processes.

• Pneumatic connection thread size of R1/8 creates a robust, airtight connection to your system
• Knurled screw lets you fine-tune the fitting to the needs of your application
• Light weight of 13.5g, so it won’t add strain to your system
• Durable nickel-plated brass materials for corrosion-resistance

• Mechanised doors
• Industrial automation
• Air brakes

This control valve supports pressures between 0 and 10 bar, so you can trust it's a safe choice for low-pressure applications.
