Solenoid Valve / Flameproof

D25-F

Flameproof-type dual-flow control solenoid valve. The coil is housed inside a flameproof enclosure, controlled by a built-in stacked electromagnetic pilot valve.

Brass-forged body with zero leakage. Two-stage flow (large and small) keeps metering accuracy high across the whole delivery range — designed for computer-controlled fuel dispensers.

Main valve diaphragm uses imported special rubber — high corrosion resistance, low-temperature resistance down to -40 °C.
Magnetic circuit parts use special stainless steel magnetic material — never rusts, no remanent magnetism.
Coil wound with imported Class F enamelled wire — low temperature rise, excellent insulation.
