Proportion-Air QB1TFEE015 Pressure Control Valve w/ Attached Regulator

The QB1TFEE015 from Proportion-Air is a high-precision electronic pressure control valve designed to regulate air or inert gas pressure with electronic input signals. It is integrated with an RG78100-BR/TP mechanical pressure regulator, allowing fine pressure control and stability across a wide range of applications. Series: QB1 (closed-loop electronic pressure controller) Control Type: Electro-pneumatic, closed-loop Pressure Range: 0–15 psi (as indicated by suffix “015”) Accuracy: ±0.2% full scale (typical) Repeatability: ±0.02% Input Signal: – 0–10 VDC or 4–20 mA (field-selectable) Output Signal: – 0–10 VDC or 4–20 mA feedback (for actual pressure) Response Time: ~25 ms (to within 5% of setpoint) Supply Pressure: Typically 1.5× to 2× the maximum output pressure Media: Clean, dry air or inert gases Port Size: 1/8" or 1/4" NPT (check label or datasheet) Mounting: Panel or manifold mountable Temperature Range: 32 °F to 158 °F (0 °C to 70 °C) Electrical Connection: M12 connector or flying leads (varies) Enclosure: IP65 rated (with appropriate connectors) Attached Regulator Model: RG78100-BR/TP Type: Mechanical precision pressure regulator Function: Provides steady inlet pressure for QB1 operation Adjustment Range: 0–100 psi (based on model code "100") Port Size: Typically 1/4" NPT Material: Brass body (BR), TP = tapped ports for pressure monitoring Mounting: Inline or bracket-mounted Relief Feature: Internal relief to exhaust downstream overpressure Use Case: Acts as a pre-regulator to stabilize input supply pressure to QB1 unit
