OBE (on board electronics) design - less susceptible to failure .integrated amplifiers are plug and play - no in-field adjustment required for gain, deadband compensation or dither - even on replacement valves easy to apply - just requires power and a voltage control signal .ISO valve sizes 3, 5, 7, 8, and 10 ,IP67 rated and CE marked,
The critical specifications engineers evaluate when selecting a high performance proportional flow control valve are linearity, frequency response and hysteresis. Other important features are repeatability, power consumption, leakage, life expectancy and cost. Engineers at IQ Valves have advanced the proportional valves by designing units that meet the high performance end of all the above mentioned specifications while keeping the valve simple enough to hold costs down. IQ Valves has achieved an unparalleled linearity, an exceptionally high frequency response of 250 Hz. and low hysteresis using a unique solenoid construction.

Directly controlled and pneumatically actuated pressure control valves provide continous, stepless pressure regulation. Adjustment time between pressure settings is less than one second. Regulated pressure remains constant regardless of system conditions. Pneumatically actuated pressure control valves are adjusted by either proportional control valve (requires 0 - 10 V control signal) or manually. Complete isolation of the control section from the media makes them insensitive to dirt.
