14L43-ZCZ Magnatrol Solenoid Valve (G14L43SC-ACTZCZ)

Overview

The Magnatrol 14L43-ZCZ Solenoid Valve (G14L43SC-ACTZCZ) is a 3/4″ normally closed, full-port bronze solenoid valve engineered for dependable control of liquids and gases in HVAC and industrial applications. Part of Magnatrol’s trusted Type “L” series, this valve is designed to operate with zero differential pressure, making it ideal for systems with low or fluctuating pressure conditions.

Built with a rugged bronze body and a continuous-duty coil, the 14L43-ZCZ delivers long-lasting performance in demanding environments. Its packless construction minimizes leakage and reduces maintenance, while the full-port design ensures maximum flow capacity with minimal restriction.

This model is widely used across commercial and industrial systems where reliable on/off fluid control is critical.

How It Works

The 14L43-ZCZ utilizes a pilot-operated piston design to control flow:

• When the valve is energized, the pilot mechanism opens

• Pressure above the piston is released

• The piston lifts, allowing full flow through the valve

• When power is removed, the pilot closes and system pressure reseats the piston, stopping flow

This design allows the valve to function efficiently across a wide range of pressure conditions, including zero differential pressure.

Applications

The Magnatrol 14L43-ZCZ is commonly used in:

• HVAC systems and air handling units

• Boiler and hydronic heating systems

• Industrial process control systems

• Chemical and fluid handling applications

• Oil, gas, and compressed air systems

• Water and liquid transfer operations

Its durability and flexibility make it a preferred choice for both replacement and new installations.

Suffix Breakdown (ZCZ)

Magnatrol suffix codes identify specific configurations:

• ZCZ – Defines coil type, enclosure, and internal construction

• Variations of the 14L43 series may include options for steam, hot liquids, or general-purpose fluids

Always confirm suffix compatibility with your application before ordering.

Installation Notes

• Install in horizontal piping only

• Ensure the coil is positioned vertically (upright)

• Use a strainer upstream to prevent debris from entering the valve

• Verify compatibility with system pressure, temperature, and media
