Remote Control Float Valve

1. Product Overview

The 100X Remote Control Float Valve is the first model of X-series hydraulic control valves, specially designed for automatic liquid level control of water tanks, water towers and reservoirs.

The valve body is manufactured from QT450 nodular cast iron with blue epoxy anti-corrosion coating, standard flanged connection, PN10 & PN16 pressure grades. It works automatically relying on pipeline water pressure and small float pilot, no electricity required. It opens to fill water when tank liquid level drops, and fully shuts off water supply once reaching preset high water level, widely used in municipal water plants, high-rise buildings, irrigation reservoirs and industrial water storage tanks.

2. Working Principle

This valve system consists of main valve body and external float ball pilot:

When the water level in tank falls, the float ball drops to open the pilot bypass. The pressure inside main valve upper cavity releases quickly, medium pressure pushes main valve disc open to supply water into tank.

As water rises to target height, float ball lifts up and closes pilot channel. Pipeline water refills the main valve control chamber, internal pressure closes main valve tightly to stop water inflow automatically.

The red manual needle valve on top adjusts opening & closing speed to avoid water hammer and pipeline noise during water filling cut-off.

3. Core Features

Fully Automatic Liquid Level Control

Real-time monitoring tank water level, auto water feeding & auto shut-off, no manual operation needed, effectively prevent tank overflow and water waste.

Self-Powered Hydraulic Drive

No power supply, sensor or electric actuator. Operate completely by water medium pressure, energy-saving and stable performance.

Adjustable Anti-Water Hammer Function

Built-in flow regulating needle valve to slow valve action, eliminate pressure surge and protect tank, pipeline and pipe fittings.

Durable & Zero Leakage Structure

QT450 ductile iron valve body, brass control pipelines, EPDM soft sealing ensures tight shut-off without dripping after closing.

Easy Installation & Maintenance

Separate float pilot can be mounted remotely inside tank; pilot and diaphragm spare parts can be replaced without removing main valve from pipeline.

4. Typical Application Scenarios

Water tower, domestic & fire water tank automatic water supply control

Municipal water storage reservoir liquid level management

Farm irrigation pool automatic filling valve

Factory industrial circulating water storage tank

Hotel, hospital, school centralized water storage system
