Product Description
The Festo L, R, and V series are mechanically actuated 3/2-way valves featuring G1/4 pneumatic connections and a durable disc seat design with mechanical spring return . Available with standard roller lever (R series), angled roller lever (L series), or stem plunger (V series) actuation, these valves operate within a pressure range of 3.5 to 8 bar with a nominal flow rate of 120 L/min .
Key Features & Advantages
3/2 Normally Closed with Mechanical Spring Return: Monostable valve with mechanical spring return ensures the valve remains closed when the actuator is not engaged, providing failsafe operation for pneumatic control circuits .
Multiple Actuation Options for Diverse Applications: Available as stem plunger (V series), standard roller lever (R series), or angled roller lever (L series) to suit different cam profiles, cylinder positions, and mechanical triggering requirements .
Tool-Free NC/NO Function Change: Simple rotation of the housing top allows conversion between normally closed and normally open function, providing installation flexibility without requiring different valve models .
Robust Anodised Aluminium Housing: Durable anodised aluminium construction with NBR seals provides corrosion resistance class CRC 2 (moderate corrosion stress) and long service life in industrial environments .
G1/4 Threaded Connections with 120 L/min Flow: Female G1/4 threads provide 120 L/min standard nominal flow rate with nominal width of 3.5 mm, suitable for industrial pneumatic control circuits .
