Non-Modulating Float Valve - Main Product Image

Simple on-off level control valve for automatic tank filling and overflow prevention

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.

Key Functions

  • Automatic tank filling
  • On-off operation based on water level
  • Prevents overflow and dry running
  • Simple and reliable control
  • Maintenance-friendly design
