Product Description
The Festo LS, RS, and VS series are mechanically actuated 3/2-way valves featuring G1/8 pneumatic connections and a robust piston seat design with a durable aluminum housing . Available with roller lever (RS, LS) or stem (VS) actuation, these valves deliver a standard nominal flow rate of 120 L/min and operate within a pressure range of 3.5 to 8 bar . Designed for reliable mechanical switching in pneumatic control systems, they can also be converted to 2/2-way function by sealing the exhaust port .
Key Features & Advantages:
3/2 Normally Closed Function: 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: Available with roller lever (RS series), angled roller lever (LS series), or stem plunger (VS series) to suit different cam profiles and mechanical triggering requirements .
Tool-Free 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 Aluminum Housing: Durable anodized aluminum construction with NBR seals provides corrosion resistance (CRC 2) and long service life in industrial environments .
Low Actuation Force: Requires minimal operating force (as low as 1.8 N for roller lever variants), enabling reliable triggering with lightweight cams and reduced wear on mechanical components .
