Automatic Stainless Steel Semi Auto Changeover Gas Panel

Gas Semi-Auto Changeover Panel

Mechanical, Power-Free Continuous Gas Supply Solution

Overview

The Mechanical Gas Semi-Auto Changeover Panel ensures an uninterrupted gas supply by automatically switching between two gas sources (Primary and Standby) based on pressure differences. This fully mechanical system operates without electrical power, making it perfect for environments with unreliable or no electricity.

Key Features :- 

• Fully Mechanical Operation – No electrical components; works solely on gas pressure.
• Automatic Switchover – Switches to standby source when primary pressure drops.
• Two-Side System – Primary source active while standby remains in reserve.
• Manual Override Option – Allows manual switching when needed.
• No External Power Required – Ideal for remote or hazardous areas.
• Durable & Low Maintenance – Simple design with minimal moving parts.
• Pressure Gauge Indicators – Monitors gas pressure on both sides.

How It Works 

• Primary Side Active: Gas flows from the primary source at normal pressure.
• Pressure Drop Detection: When primary pressure falls (low gas), the system triggers a switch.
• Automatic Changeover: The mechanical valve shifts gas flow to the standby source, maintaining supply.
• Vice Versa Operation: Once primary side is refilled and pressure stabilizes, switch back happens automatically or manually.

Applications

• LPG & CNG Gas Systems
• Commercial & Industrial Gas Supply
• Restaurants & Catering Facilities
• Rural & Off-Grid Locations
• Medical Gas Systems (Oxygen, Nitrogen, etc.)

Benefits

• No Electricity Needed – Operates independently of power supply.
• Fail-Safe Operation – Ensures continuous gas flow without interruption.
• Cost-Effective – Low maintenance with no electrical parts.
• Reliable in Harsh Environments – Suitable for outdoor and high-risk locations.
