Product Overview

The F745X Multi Functional Remote Control Float Valve is an advanced liquid level control device designed for water tanks, reservoirs, and other liquid storage systems. It combines remote float control with multiple functions including flow regulation, automatic shut-off, and manual override capabilities.

Key Features

• Remote Float Control– Allows installation flexibility with float positioned away from valve
• Multi-Stage Closing– Prevents water hammer with gradual shut-off
• Adjustable Flow Rate– Precise control of filling speed
• Manual Override– Emergency open/close capability
• Corrosion Resistance– Stainless steel and bronze construction
• Low Maintenance– Simple design with few moving parts
• Universal Installation– Suitable for horizontal or vertical mounting

Technical Specifications

Working Principle

The F745X operates through a pilot-controlled diaphragm mechanism. When the liquid level drops, the float descends, opening the pilot valve which releases pressure from the diaphragm chamber. This allows the main valve to open, filling the tank. As the liquid level rises, the float lifts, closing the pilot valve and building pressure in the diaphragm chamber to gradually close the main valve.

Structural Features

• Diaphragm Actuator– Provides positive sealing with low operating force
• Adjustable Float Arm– Precise level setting capability
• Stainless Steel Linkage– Corrosion-resistant mechanical components
• Flow Control Knob– Easy adjustment of fill rate
• Bypass Valve– Manual operation during maintenance

Applications

• Water storage tanks and reservoirs
• Cooling towers and condensate systems
• Industrial process tanks
• Fire protection water storage
• Agricultural irrigation systems
• Sewage and wastewater treatment

Installation & Maintenance

Installation Requirements

• Install in accessible location for maintenance
• Ensure proper support for float cable
• Maintain minimum 5×DN straight pipe upstream
• Protect float from turbulence or obstruction
• For vertical installation, orient valve according to markings

Maintenance

• Inspect float mechanism quarterly
• Check diaphragm annually for wear
• Lubricate moving parts as needed
• Test manual override function periodically
• Clean strainer (if equipped) every 6 months
