Servo Pressure Regulators - Type 3511/3521 Digital
  The 3511 offers solenoid valve technology with forward flow equivalent to standard industrial electronic regulators or I/P transducers. Available with local keypad programming option or RS-485 Digital Communications for PLC or PC control. Dual solenoid valves with internal pressure sensor and advanced microprocessor control. A built-in air volume booster provides the 3511 with forward flow up to 19 SCFM. Proportional - Integral - Derivative (PID) control. Ranges from 0 to 150 psig. Reverse flow (exhaust) of up to 7 SCFM. The double loop (3521) option permits 0-10 VDC feedback from a remote sensor. The keypad is available with a four digit display of the output pressure.

Applications include; Gripper Control, Welding Operations, Actuator Control, Machinery Automation, Precision Robotics, Tire Production & Testing, Web Tension Semiconductor Equipment and Molding & Forming Operations.
