Sporlan Solenoid Valve Pilot Control 1/4″ 180

Sporlan Type 180 Solenoid Pilot Control Valve

The Sporlan Type 180 Solenoid Pilot Control Valve is a specialized component designed to enhance the functionality of thermostatic expansion valves (TEVs) in refrigeration and air conditioning systems. By providing positive shut-off of liquid lines, it ensures efficient and reliable system operation.

Key Features

• Cost-Effective Installation: With a universal size, the Type 180 reduces inventory requirements and simplifies installation processes.
• Positive Liquid Line Shut-Off: Acts on the TEV to ensure complete closure of the liquid line, preventing unwanted refrigerant flow during off cycles.
• Compact Design: The valve’s streamlined construction allows for integration into various system configurations without occupying excessive space.

Operational Overview

The Type 180 operates by influencing the pressures acting on the TEV diaphragm:

• When Energized: The solenoid coil activates, sealing the high-pressure port. This allows true suction pressure to act beneath the TEV diaphragm, enabling normal operation.
• When De-Energized: The low-pressure port closes, and the high-pressure port opens, applying liquid line pressure beneath the TEV diaphragm. This pressure overcomes the bulb and spring pressures, causing the TEV to close and halt refrigerant flow.

Applications

The Type 180 is versatile and can control multiple TEVs simultaneously, accommodating systems up to 180 tons for R-22 refrigerant. It is suitable for various applications, including:

• Thermostatic Control: Integration with thermostats for temperature-based regulation.
• Pressure Switch Activation: Utilization with pressure switches for system pressure management.
• Manual Control: Direct manual operation for specific system requirements.

Installation Guidelines

For optimal performance, adhere to the following installation practices:

• Connection Tubing: Utilize standard 1/4″ soft copper tubing for all connections.
• Contaminant Protection: Install a Sporlan Catch-All® Filter-Drier ahead of the TEV to safeguard against contaminants that could impede valve operation.
• Mounting Orientation: The valve can be mounted upright or on its side but should not be positioned with the coil housing below the valve body.

Electrical Specifications

The Type 180 is compatible with various electrical configurations:

• Standard Coil Ratings: Available in 24/50-60, 120/50-60, and 208-240/50-60 volts/cycles.
• Power Consumption: Operates at 15 watts for AC and 18 watts for DC applications.
• Maximum Operating Pressure Differential (MOPD): 300 psi for AC and 225 psi for DC.

Maintenance and Service

The Type 180 is designed for durability and requires minimal maintenance. However, if operational issues arise:

• Pressure Testing: Install a pressure gauge in the external equalizer connection to monitor pressure variations during operation.
• Troubleshooting: If the TEV fails to close properly, inspect the electrical circuit, ensure no restrictions exist before the control and filter-drier, and verify that the low-pressure port is sealing correctly.

By integrating the Sporlan Type 180 Solenoid Pilot Control Valve into your system, you can achieve precise control over refrigerant flow, enhancing overall system efficiency and reliability.
