36A47 Magnatrol SOLENOID Valve

The Magnatrol 36A47 SOLENOID Valve 2″ NC 0/100# 120VAC BRONZE

Overview

The Magnatrol 36A47 is an electromechanical, two-way, full port solenoid valve with a bronze body designed for automatically controlling the flow of fluids and gases. It is an internal pilot-operated or direct-acting valve. It features a Normally Closed (N/C) operation, meaning it is designed to open when the coil is energized (Energize to Open) and closes when power is de-energized. A key operational characteristic is that it requires zero differential pressure to open, allowing it to operate from zero to its maximum rated differential pressure.

Features

• Operation: Normally Closed (N/C), opening upon coil energization and closing when power is cut off.
• Construction: Bronze body, full port, 2-way straight-thru design, and packless construction.
• Pressure Operation: No differential pressure is required for the valve to open.
• Coils: Continuous duty, encapsulated coils (general service Class B standard) are available for all AC and DC voltages.
• Installation: Must be mounted in a horizontal pipe with the solenoid enclosure vertical and on top.

Specifications

• Part Number: 36A47
• Pipe Size: 2 inch NPT
• Maximum Differential Pressure (Max Diff PSI): 100 PSI
• Control Voltage (Common AC): 120 V-AC, 60 HZ (other voltages like 24 VDC are also available)
• Power Rating: 45 W
• Body Material: Bronze
• Weight: Approximately 27 to 32 lbs
• Max Fluid Temperature: Typically rated up to 400° F (for the bronze series)

Applications

The 36A47 solenoid valve is used for controlling the flow of general service fluids, including Water, Oil, Air, Gas, Solvents, Brine, and Vacuum, provided they are not corrosive or contain sediment. It is a general-purpose valve often employed in HVAC-R and process control systems for tasks such as:

• Regulating refrigerant flow in chiller units, air conditioning, and refrigeration systems.
• Managing water flow in water heater systems and water-source heat pumps.
• Conducting automatic pump down of refrigerant systems to prevent liquid refrigerant migration.
• Controlling fuel (gas/oil) flow to burners in heating systems and furnaces.
