AFC 142 Electric Solenoid Lockoff

The AFC-142 is a normally-closed electrically controlled lock-off valve with built-in filtration, designed for propane fuel systems. It helps to shut off fuel flow when power is removed, protect downstream components from dirt, and is suitable for automotive, engine conversion, or LP-gas installations requiring safety and reliability.

Key Features

• Normally-closed solenoid valve actuated by 12V DC (stocked also in 24V variants)

• Built-in 40-micron replaceable filter to handle dirty or unclean gas, helping protect downstream equipment

• Rated working pressure: ~312 PSI (LP gas service)

• Low power draw: around 1.0 Amp at 12V, minimizing impact on electrical systems

• Heavy-duty, die-cast aluminum body and filter bowl, corrosion-resistant design

• Large filter capacity and easy access for maintenance

• Wide ambient temperature rating: −40°F to +250°F (approx. −40°C to +121°C)

Specifications

Applications

• Engine conversion kits (vehicles, generators) using propane, where you need a shut-off valve that also filters gas

• Fuel systems exposed to contaminants (e.g. off-grid, industrial, or dusty environments)

• Safety shutdowns where power loss should automatically close gas flow

• Systems with high inlet pressure where protection of downstream components (regulators, vaporizers, injectors) is needed

Why Choose AFC-142

The AFC-142 offers safety, filtration, and electric control in one combo unit. It helps simplify installation by combining lock-off and filtering, reduces parts count, and offers reliable shut-off under power failure or during emergency. Its rugged build, high pressure rating, and tested reliability make it a good choice for conversions or any installation needing secure and clean gas supply.
