141S46 Magnatrol Solenoid Valve (G141S46SC-ACTS)

141S46 Magnatrol Solenoid Valve (G141S46SC-ACTS) 1 1/2″npt N/C 120V 180#STEAM

Overview

The Magnatrol 141S46 (G141S46SC-ACTS) is a Type S, full port bronze solenoid valve designed for process control applications. It is an internally pilot-operated valve with a Normally Closed (N/C) unactuated state, meaning it opens when the coil is energized and closes when power is de-energized. This valve is designed to operate from zero to its maximum differential pressure, and while it is part of Magnatrol’s high-quality line of valves, some sources indicate it may be discontinued by the manufacturer.

Features

• Operation: Normally Closed (N/C), opening upon coil energization. The valve mechanism is internal pilot-operated, where energizing the coil opens a pilot valve to relieve pressure above the piston, allowing it to lift and open the valve.
• Construction: Cast Bronze body with a Globe Pattern and NPT threaded ends. It features a full port, straight-thru design, and packless construction.
• Coil: Encapsulated Class H coil is standard, designed for continuous duty with AC and DC voltages.
• Pressure Operation: No differential pressure is required to open the valve, and it operates up to the maximum differential pressure.
• Installation: Must be mounted in a horizontal pipe with the solenoid enclosure vertical and on top.
• Standards: Meets standards including Explosion-Proof & NEMA 4; NEMA 12 (General Purpose); and NEMA 4X.

Applications

The 141S46 Solenoid Valve is primarily used to control the flow of steam, which must be free of sediment. It is a general-purpose process control valve also suitable for controlling the flow of water, oil, air, gas, solvents, brine, vacuum, and any other fluids that are non-reactive with the valve’s bronze and stainless steel construction materials and are free of sediment.
