Float valve IMI TA type 333 by IMI TA, MPN 10028993

IMI TA float valve type 333 is a mechanical float-operated valve designed to provide automatic level control in tanks and closed systems. Manufactured by IMI TA, this float valve operates with a buoyant float mechanism that opens and closes the inlet flow in response to the liquid level, enabling reliable automatic filling and maintaining a set level without electrical control. The design suits water and other compatible liquids in HVAC, plumbing and industrial environments where simple and robust level regulation is required.

Advantages

The valve delivers straightforward mechanical control of liquid level without the need for power supply or electronic sensors, reducing complexity and failure points. Its float-actuated operation responds directly to level changes for immediate shut-off or fill control. The construction is intended for continuous service in typical HVAC and plumbing installations and provides consistent performance in routine filling and overflow protection tasks.

Suitable for

• Automatic filling of storage or buffer tanks in HVAC systems
• Plumbing installations requiring level regulation
• Industrial processes where simple mechanical level control is preferred
• Closed systems and condensate return tanks

Key specifications

• Operation: Mechanical float-actuated valve for automatic level control
• Media: Water and compatible liquids
• Control action: Opens and closes inlet flow according to liquid level
• Mounting: Tank-mounted connection suitable for standard inlet fittings
• Maintenance: Designed for periodic inspection and simple servicing

How to use

Install the float valve in the tank inlet following the system manufacturer’s mounting guidelines and ensure correct orientation so the float can move freely. Connect the inlet piping and verify sealing at the connection points. Adjust the float position or linkage, if provided, to set the desired fill level. After installation, test operation by filling the tank slowly and observing that the valve closes at the set level and reopens when the level drops. Perform periodic inspections to check for debris, seal condition and free movement of the float.

Usage recommendations

Use the valve with compatible liquids and within the pressure and temperature ranges recommended for mechanical float valves. Avoid environments with aggressive chemicals or solids that can impair float movement. Schedule routine inspections and cleaning to ensure reliable long-term operation.
