VR8205M2948 / VR8205A2800 (Honeywell/Resideo)
Description: 24 Vac, Dual Safety Automatic Valve, Direct Spark Ignition (DSI / Hot Surface Ignition) Combination Gas Valve, designed for natural gas / LPG combustion equipment. I. Common Core Specifications (VR8205 Series)
Brand: Honeywell (now Resideo)
Voltage: 24 Vac / 50–60 Hz; Current: 0.5 A
Structure: Manual Valve + Dual Automatic Valves + Integrated Pressure Regulator
Safety: Dual-stage safety shutoff (automatic valve closure upon power failure, gas supply interruption, or flame failure)
Compatible Fuels: Natural Gas (NG) / Liquefied Petroleum Gas (LPG); field-convertible
Connections: 1/2” NPT inlet and outlet; installable at any angle (0–90°)
Adjustments: Top-accessible controls (pressure regulation, wiring connections, manual shutoff)
Certifications: UL/CSA/CE; Compliant with North American gas safety standards
II. Model Distinctions (A vs. M)
1) VR8205A2800 (Standard Model)
Full Model Name: VR8205A2800/B
Port Size: 1/2” × 1/2” NPT
Pressure Regulation: 3.5” WC (≈0.87 mbar); Fixed Outlet Pressure
Flow Rate: 20–200 cfh (Natural Gas), approx. 0.5–5.4 m³/h
Ignition: Standard Fast-Opening; Compatible with Direct Spark Ignition / Hot Surface Ignition systems
Typical Applications: Residential / Commercial wall-mounted boilers, water heaters, small boilers (≤150,000 BTU/h)
2) VR8205M2948 (Modureg Adjustable Model)
Full Model Name: VR8205M2948/B
Port Size: DN20 (3/4”); Higher flow capacity
Pressure Regulation: Modureg Adjustable; Wider adjustment range (adaptable to different gas types)
Flow Rate: 30–415 cfh (Natural Gas), approx. 0.8–11.2 m³/h; Higher power output capability
Ignition: Standard Fast-Opening; Compatible with industrial burners and medium-to-large boilers
Key Differences: M = Modureg Adjustable Pressure + Higher Flow/Larger Port Size; A = Fixed Pressure + Standard Flow Rate
III. Operating Principle
Thermostat Ignition Request → First Solenoid Valve (Fast-Opening) Opens.
Successful Ignition → Second Diaphragm Valve (Pressure-Regulating) Opens, maintaining stable outlet pressure.
Flame Failure / Power Loss / Overpressure → Both valves simultaneously execute a rapid shut-off to prevent gas leakage.
IV. Model Selection and Replacement
VR8205A2800: Low Power, Fixed Pressure, 1/2” Port → Preferred Choice for Residential Equipment
VR8205M2948: Medium-to-High Power, Adjustable Pressure, 3/4” Port → Industrial / Commercial Equipment
