Spartan Scientific 6200-040-AAB6C Solenoid Valve 1/4 Npt

Product Description

The SPARTAN SCIENTIFIC 6200-040-AAB6C is a direct-acting, 2-way, 2-position solenoid valve designed for fluid and gas control in HVAC, plumbing, and industrial process systems. It operates on 24 volts AC and features a normally closed configuration, meaning flow is blocked until the coil is energized. The body is constructed from glass-filled nylon for lightweight durability and chemical resistance. Viton seals provide compatibility with a wide range of media. The valve is FDA approved, making it suitable for applications where food-grade or potable-water compliance is required. Licensed HVAC technicians and plumbers are the primary installers of this valve type.

This valve is suited for residential and light commercial HVAC systems, water treatment equipment, pool and spa controls, and other fluid-handling applications requiring 24-volt AC switching. The 1/4 inch NPT port size fits standard small-bore piping and tubing connections common in zone control, chemical dosing, and process automation installations. The DIN spade coil connection simplifies field wiring and coil replacement without tools. Operating temperature range runs from 10 degrees F to 50 degrees F, which defines its rated service window.

Key Features

• Direct-acting operation with no minimum pressure differential required
• Normally closed configuration — flow blocked when coil is de-energized
• 24-volt AC coil with DIN spade connector for easy field wiring
• Glass-filled nylon body — lightweight, corrosion-resistant construction
• Viton seals for broad chemical and media compatibility
• FDA approved for use in food-grade and potable-water adjacent applications
• No manual override — automatic actuation only

Compatibility

Designed as an OEM-style replacement or new-installation direct-acting solenoid valve for systems using 1/4 inch NPT connections and 24-volt AC control circuits.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes and the IPC or IFGC as relevant to the system. Shut off fluid supply and de-energize the control circuit before removing or installing the valve. Verify flow direction markings on the valve body before threading into the line, and use appropriate thread sealant on NPT connections. Do not exceed the rated maximum working pressure or operating temperature range during service.
