Electronically Controlled Proportional Pressure Regulators Electronically controlled precision regulators for variable pressure control

Electronically Controlled Proportional Pressure Regulators - Series RESK 3478.3

Precise Pressure Control – Digital, Dynamic, Reliable
 

The ROSS Proportional Pressure Regulators Series RESK 3478.3 are designed for precise and dynamic pressure control in automated processes. By combining an electronic pressure sensor, two integrated solenoid valves, and a closed-loop control architecture, they ensure accurate and repeatable pressure regulation - even under changing loads.

Key Benefits:

• Compact and low-maintenance design
• Excellent repeatability and minimal hysteresis (±0.2%)
• Good linearity (±0.5%) and adjustable sensitivity (10 - 300 mbar)
• Fast response to pressure changes
• Integrated display and buttons for indication and programming
• Optional version available with IO-Link interface

Technical Details:

• Input pressure: 1-11 bar
• Control range: 0.05-10 bar
• Flow rate: up to 20,000 l/min
• Exhaust flow rate: up to 2,000 l/min
• Setpoint input: 0-10 V / 4-20 mA
• Feedback output: 0–10 V / 4-20 mA
• Power supply: 24 VDC
• Port sizes: G 1/8 to G 2
• Protection class: IP65

Typical Applications:

• Test benches and measurement systems
• Clamping, pressing and lifting devices
• Load-variable pneumatic control circuits
• Automation and mechanical engineering

Smart Control:

With integrated feedback and control (closed loop), the RESK 3478.3 ensures consistently accurate pressure regulation. The built-in pressure sensor continuously monitors the output pressure and actuates the internal valves to align the actual pressure with the desired setpoint.
