The Honeywell V88A1618 is a 24V diaphragm gas valve designed to control the flow of natural gas in various HVAC equipment. It features a compact and durable aluminum construction, measuring 1 inch in size and weighing approximately 3.04 pounds. This valve operates with a maximum pressure rating of 1/2 psi and within a temperature range of 32°F to 125°F for safe and reliable operation. It utilizes a threaded NPT connection for secure installation into your HVAC system. The valve functions with a solenoid that opens a diaphragm when energized, allowing natural gas to flow through. Conversely, when de-energized, the diaphragm closes and stops the gas flow. This precise control of natural gas is essential for the safe and efficient operation of various HVAC equipment, including atmospheric boilers, commercial water heaters, and rooftop heaters.
How to install an expansion valve for refrigeration?
Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.
These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.
Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...
