Product Overview

The FESTO R-3-1/4-B, manufacturer part number 8985, is a mechanically actuated pneumatic roller lever valve designed for pneumatic directional control and mechanical position-actuated switching. This model features a 3/2-way normally closed, monostable valve function with a roller lever actuator and direct-operated piston seat construction. The manufacturer specifies a standard nominal flow rate of 600 L/min, normalized according to DIN 1343, and an operating pressure range of -0.95 to 10 bar. All three pneumatic connections use G1/4 ports, with a 7 mm nominal size. Its manufacturer-specified actuating force is 26 N and the rated ambient temperature range is -10°C to +60°C. The housing is made from die-cast aluminium, with NBR seals and a manufacturer-specified product weight of 230 g. The valve is designed for through-hole mounting. FESTO lists explosion-protection zones 1, 2, 21 and 22 in its technical data; suitability for a particular hazardous-area installation must be checked against the applicable manufacturer documentation. No solenoid coil or electrical supply is required for the mechanical actuation function. Actual supplied photographs show the FESTO roller lever valve with its product nameplate marked R-3-1/4-B, part number 8985, and matching FESTO packaging labeled Made in Brazil. Please verify pneumatic connections, actuation conditions, mounting requirements and required operating pressure before ordering.
