Description
The 4V310-08 series is a high-performance, direct-acting 5/2-way (5-port, 2-position) pneumatic solenoid valve designed for industrial automation and machinery. This compact valve features a universal G1/4″ port size and is capable of handling high flow rates (Cv up to 1.2) with low power consumption. The series includes multiple variants: 4V31008A (Standard AC/DC), 4V31008B (Low Power DC), 4V310-08-E (Explosion-proof), 4V310-08-F (High Frequency), 4V310-08-C (Low Temperature), and 4V310-08-XO (Manual Override). It operates on the principle of direct solenoid actuation without a pilot, making it suitable for applications requiring fast response times and no minimum pressure requirement.
