The ASCO NF8327B102 Solenoid Valve is a robust and versatile component designed for a range of industrial applications. Its body material is constructed from stainless steel, ensuring durability and resistance to corrosion. With a Cv flow rating of 0.52 and a Kv flow rating of 0.45, it offers efficient flow control. This 3/2 universal function valve features NPTF 1/4 pipe/port type and size, making it adaptable to various systems. It operates via direct-acting solenoid actuation and can handle a diverse range of media, including light oil, air, inert gases, and water.

The valve accommodates operating pressures ranging from 0 to 10 bar for air, water, and light oil. Weighing 2.60 kg, it is equipped with an H-class coil and operates within an ambient temperature range of -20 to 60 °C, while also accommodating the same fluid temperature range. The orifice size of 5.7 mm ensures efficient flow control, and it operates on a 24 Volts DC voltage. Complying with ATEX Zone 1-21 and IEC 61508 standards and regulations, this solenoid valve is suitable for use in hazardous environments. Its robust construction and adherence to safety standards make it a reliable choice for fluid and gas control systems in demanding industrial settings.

The ASCO NF8327B102 Solenoid Valve offers versatile manual control options for user convenience and safety. It comes with two different manual operation modes: a push-type spring return, indicated by the suffix MO, and a screw-type manually return, marked as MS. With the push-type MO option, users can easily switch the valve to the "ON" position by pushing the button, and upon release, it returns to the "OFF" position. Conversely, the screw-type MS allows users to turn the knob clockwise to manually engage the valve in the "ON" position and counterclockwise to return it to the "OFF" position. Furthermore, the valve features a No Voltage Release (NVR) mechanism, ensuring that the valve remains inoperative when the solenoid is energised alone. To activate the valve in the "ON" position, one must energise the solenoid and briefly push the button, latching it in place. In the event of an electrical power interruption, the valve will unlatch, automatically returning to the "OFF" position for added safety.

For additional flexibility, an adapter compatible with under-pressure removable operators MO and MS, in accordance with TPL-26710, is available. This adapter allows for easy removal of the operator and reinstallation, keeping the system pressurised as needed while enabling operators MO and MS to function as described above.For Ex db Prefix "NF/WSNF/WSCR" enclosures, a 1/2" NPT threaded entry hole is provided, with M20 x 1.5 (prefix "ET") available as an option, although cable glands are not included. Additionally, all DC solenoids with metal enclosures come equipped with switch-off peak voltage suppression diodes. To meet the requirements of IEC 61508 (SIL), the valves must be fitted with a specific exhaust protector, as illustrated on page 6, or an equivalent alternative.
