In the event of a power failure in your solenoid valve, this manual override from Festo is on standby to save the day. It lets you lock down your valve in its operating position to keep it working. You can set it with a simple screwdriver, so it's easy to use even without specialist tools. A built-in spring mechanism returns the plunger to its original position, taking the task of resetting it off your hands.

• PA6-reinforced material housing resists hard impacts and heat
• Can be mounted in any position for flexible assembly
• Spring return mechanism is made from high-alloy stainless steel that resists corrosion

• Laboratories
• Agricultural equipment
• HVAC systems

A solenoid valve controls the flow of air or liquid in your machinery by opening or shutting channels. It typically consists of a coil and a plunger. In an NC system, when electrical energy passes through the coil, it raises the plunger and allows the fluid to pass through. When the coil is de-energised, the plunger returns to its original position, stopping airflow.
