18A44 Magnatrol Solenoid Valve

The Magnatrol 18A44 SOLENOID Valve 1″ N/C 120V SOLENOID

Overview

The Magnatrol 18A44 is a full port, two-way Normally Closed (N/C) solenoid valve, classified as Type “A” in the Magnatrol series. It is a bronze construction valve designed for general-purpose industrial and commercial fluid control. As an internal pilot-operated or direct-acting valve, it is designed to operate from zero to its maximum differential pressure, requiring no differential pressure to open. The valve opens when the coil is energized (Energize to Open) and closes when power is de-energized.

Features

• Operation: Normally Closed (N/C), opening upon coil energization.
• Construction: Cast Bronze body with Globe Pattern, NPT ends, and a full port design for straight-thru flow.
• Coil: Encapsulated Class B coil is standard (Class H available), designed for continuous duty with both AC and DC voltages.
• Pressure Operation: Operates from zero to maximum differential pressure; no differential pressure is required for the valve to open.
• Wetted Parts: Piston is Cast Bronze, Pilot Valve is 303 Stainless Steel, Spring is 302 Stainless Steel, and the standard Orifice Seal is Buna-N (Viton or Glass Filled PTFE available).

Specifications

Applications

The 18A44 solenoid valve is used to control the flow of general service fluids, including Water, Oil, Air, Gas, Solvents, Brine, and Vacuum. It is suitable for any fluids that are not reactive with the construction materials and are free of sediment. It is commonly used in various industrial and commercial applications. The valve must be mounted in a horizontal pipe with the solenoid enclosure vertical and on top.
