Proportion-Air High Resolution Electronic Pressure Regulator. Part No: QPV1TBMISZN30IHGXAL. New in the Box. Thank you for your consideration and support of STEM education!
The Proportion-Air QPV-1 is an advanced electronic pressure regulator designed for precise air pressure control. It achieves exceptionally fine and stable pressure adjustments with virtually no deadband by utilizing a true proportional inlet valve and a standard ON/OFF exhaust valve, both driven by an electrical command signal. This complete closed-loop system integrates valves, a manifold, housing, and electronic controls, making it ideal for applications requiring accurate pressure management, such as leak testing, microfluidics, and automated laser welding.
Description:
The QPV-1 is an advanced proportional valve designed for highly accurate and continuous pressure regulation. Unlike traditional ON/OFF solenoid valves, the QPV-1 provides smooth, stepless control, making it ideal for applications requiring exceptional precision.
How it Works:
Input Command: An electrical signal (e.g., voltage) is sent to the QPV-1, setting the desired output pressure.
Internal Control: The valve's internal analog PID control circuit continuously compares this command signal with a feedback signal from its integrated pressure transducer.
Inlet Modulation: Based on this comparison, the true proportional inlet solenoid valve precisely modulates its opening, controlling the flow of air into the system. This variable orifice control ensures precise pressure delivery.
Exhaust Regulation: Simultaneously, an ON/OFF exhaust valve vents any excess pressure from the system, maintaining stability.
Closed-Loop Regulation: This continuous feedback and adjustment process ensures the output pressure precisely matches the input signal. This closed-loop system eliminates the digital stepping common in traditional valves, guaranteeing high accuracy and smooth operation.
Key Features & Benefits:
High Resolution & Accuracy: The QPV-1 offers exceptional resolution (up to ±0.005% of full scale) and accuracy (up to ±0.2% F.S. in some models), enabling precise control over even the smallest pressure changes.
Closed-Loop Control: The integrated pressure transducer and PID circuit provide continuous, automatic adjustments, ensuring stable and accurate pressure output.
Smooth, Continuous Control: By utilizing a true proportional inlet valve, the QPV-1 bypasses the discrete steps of traditional ON/OFF valves, delivering seamless and continuous pressure modulation.
Robust Design: Capable of withstanding shock and vibration up to 20 Gs, the QPV-1 can be mounted in any orientation, offering installation flexibility and durability.
Integrated & Compact: This single unit consolidates multiple components—valves, manifold, and electronic controls—into a compact design, simplifying system integration.
Customizable: Available in a wide range of pressure options (from inches of water column to 150 PSI), the QPV-1 can be customized to meet specific application requirements.
Common Applications:
Medical Device Manufacturing: Essential for precise control of pneumatic forces in sensitive medical equipment.
High-Pressure Leak Testing: Used for accurate control and monitoring of pressure during part testing.
Laser Welding: Regulates shield gas flow to ensure consistent and high-quality welds.
Microfluidics: Provides highly precise control over minute fluid volumes in advanced microfluidic systems.
Force Control: Ideal for applications such as testing the breaking point of electronic components using Air-Pel cylinders, where precise force regulation is critical.
