Available with Murali Pneumatics, your authorized Festo dealer in Coimbatore.
Product Description
The Festo VUVS-L25-B52-D-G14-F8 is a 5/2-way bistable solenoid valve from Festo's VUVS series — a compact yet robust platform designed for universal directional control in pneumatic systems. With a standard nominal flow rate of 1300 l/min and a piston spool construction rated for 1.5 to 10 bar operating pressure, this valve handles medium to heavy-duty cylinder actuation across a wide range of industrial applications. This is the base valve body supplied without solenoid coil or plug socket, giving you the flexibility to select the exact coil voltage and connector your system requires.
Key Features
- 5/2 bistable (double solenoid) — holds its last switched position without continuous power, reducing energy consumption
- 1300 l/min standard nominal flow rate — sufficient for medium to large bore pneumatic cylinders
- G1/4 threaded pneumatic ports (all 5 ports) — standard BSP connections for straightforward piping
- Piston spool design, 26.5 mm valve size — reliable high-cycle switching with consistent performance
- Die-cast aluminium housing (painted) with HNBR/NBR seals — corrosion-resistant and durable in harsh environments
- Manual override (detenting + non-detenting) — allows manual valve operation during commissioning, setup, or power failure
- Internal pilot air supply — no external pilot line needed for most applications
- 11 ms switching time (reversal) — fast response for high-speed automation sequences
- Flexible mounting: manifold rail or through-hole — adapts to panel mounting or valve terminal configurations
- ISO 14644-1 Class 6 cleanroom suitability — approved for controlled environments in electronics and pharmaceutical production
