NON MODULATING FLOAT VALVE
Model-AD-100 NMFV
Overview
A Non-Modulating Float Valve is a hydraulically operated, self-actuated control valve designed to automatically fill tanks, reservoirs, or sumps to a preset level and shut off completely when the level is reached.
Unlike modulating float valves, this valve operates in a simple on-off mode, providing reliable and maintenance-friendly level control for water storage systems.
Key Features
- ✓Simple on-off operation
- ✓Automatic tank filling
- ✓Fully automatic operation
- ✓No external power required
- ✓Reliable and low-maintenance
Working Principle
The valve works automatically using line pressure and a float mechanism, without external power:
- ✓As the water level drops, the float moves downward, causing the valve to open fully and allow water inflow.
- ✓As the water level rises to the preset level, the float moves upward, causing the valve to close completely, stopping the flow.
- ✓The valve provides simple and reliable level control, suitable for tanks where precise modulation is not required.
This ensures automatic filling and overflow prevention in an efficient, low-maintenance manner.
