Technical specifications

Construction 3/3-way with rotating spoolClosed loop control circuit and metal to metal seal
Power supply 24 V DC +/- 10%, max absorption 1.5 A
Controlinput signal 0-10 V (on request 4...20 mA or +/- 10 V DC)
Command method If the command signal is lower than 50%, the valve establishes a linkbetween inlet 1 with outlet 2. If the setpoint value is higher than 50%, theport 2 is connected with the exhaust 3.
Hysteresis Linearity LRWD2 = 1% / 1% FSLRPD2 = 0,2% / 0,3% FS
Response time ~ 5 ms
Operating temperature 0 ÷ 50°C
Mounting position In any positionN.B.: The optimal distance of the servo valve from the controlledvolume should not exceed 2m. Longer distances will lower the controlperformance.
Fluid Filtered air 5 μm, non-aggressive gases
Relative air humidity Max 90%
Supply pressure -0.9 ÷ 10 bar
Leakage < 1% of max flow rate
